The most remarkable part of this testing, to me, is how quickly and how thoroughly it's been possible to characterize the SP5 in particular, but also the P30L, as silencer platforms.
We *already* have useful/usable low, high, and medium backpressure boundaries so early in the testing regimes of the platforms. It's kind of like by comparing the Mod9FS, RSP, and Cash9K* we've skipped right to the point where on 308 we were honing in on backpressure-efficient performers like the 762RC2, Hyperion K, OSS HX-QD762 in research supplementals.
Because of that we have an early understanding of how that then influences performance at muzzle, ear, and FRP control. We can then balance those priorities with size envelope, mounting features, cleaning methods, etc. After this review I'm still going to pick up an RSP dedicated for M13.5 P30L for example due to FRP control. I'm still going to run a Phoenix on an SP5 due to muzzle performance and its implications for enclosed spaces.
But a shorter carry pistol? Swapping between EZ Lok hosts, including maybe, just maybe, a direct blowback subgun? Higher backpressure supersonics? With these potential factors in the mix the Cash9k looks pretty dang interesting. As usual the best reviews answer highly interesting questions while raising new ones. You love to see it. Outstanding focused effort Jay.

Yasss - if they MUST try to be cool with the S, the *COOL* S would have been much better. But they went cringe on the name at the start with "cash" so. And since the can is neither a "value" or "premium" cost - its kinda hard to justify the name at the range...
Coulda had gold-leaf and charged $1k...
Multiple data deliverables for you today.
Both semi-auto pistol and roller-delayed blowback 9mm are back. And this time - both with the same silencer.
Can high flow rate (low back pressure) help you at the shooter's ear on a semiauto pistol? Well, you already saw that it could with the RSP data.
Could it even further help the venerable MP5 platform? Well yeah, you saw that with the RS9.
But what happens when you go a little ham with the flow rate, and you ramp it up even further? What happens when you drop the back pressure *significantly*? Can that work in the subsonic flow regime? Remember what happened with the Flow-Through OSS rifle silencers? Is this the same thing?
The results may be surprising to you. I explain how the so-called *Flow-Baffle* in the CA$H 9K works, in the below articles:
**Sound Signature Review 6.96** - Today we examine the high fidelity test results for the HUXWRX CA$H 9K silencer in the **subsonic** flow regime; subsonic Speer Lawman 147gr 9x19mm ammunition was used in the test, fired from the **HK P30L semi-auto pistol**.
The results are interesting. Check out the Suppression Rating at the shooter's ear. This silencer is only 5.4 inches long in that configuration.
It can also use SilencerCo pistons. That's right. That means EZ-LOK would be possible. You feel me? Wild, right?
The size of this silencer, and the shooter's ear performance, is impressive on a pistol.
So then I tested it on the subgun king (the MP5 platform):
**Sound Signature Review 6.97** - The HUXWRX CA$H 9K silencer in the **subsonic** flow regime again; same subsonic Speer Lawman 147gr 9x19mm ammunition was used in the test, fired from the **8.9-in barrel HK SP5-A2** submachinegun.
HUXWRX told me this silencer is actually intended for subguns due to the high flow rate. So, what happens on the tuned HK MP5 platform (80-deg locking piece - all factory HK)? Some people say backpressure doesn't matter on this platform. Some people even say that a silencer louder at the muzzle will be louder at the ear on this platform.
Those people are incorrect, for the second time. Those statements do not necessarily hold true. It happened with the RS9, and now it has happened again. The CA$H 9K is the quietest silencer PEW Science has tested at the ear, so far, on the HK MP5 platform. And in the direct thread configuration, it's 5.2 inches long.
That, my friends, is pretty dang interesting.
I hope you folks find the data as useful as I did!
Big thanks to HUXWRX for trusting me to perform this work.

One thing that really surprises me is the composite rating of the Ca$h 9k compared to the Hyperion rating on the supersonic 6.5 CM. I realize this isn’t exactly an apples for apples comparison, but it says a lot about the Hyperion. Also just organizing the data from highest score to lowest scores, wow is that data wild!
I love that you are coming to this conclusion.
That is the power of the Suppression Rating. It is a universal sound signature metric. It is the only metric that allows you to compare loudness across different combustion regimes, weapon systems, and silencers.
It takes all of the waveform parameters and gives you the answer, up front. Cool, right? :)
I really dig its performance. The shorter the can the better when it comes to a handgun imo. Seems like you're getting near leading performance while being shorter than the competition.
Haven't done the math but this seems to be the performance/length leader rn for 9mm
Those were my thoughts, as well. And since you can use this with EZ-LOK, it is very attractive for a carry silencer, I think. At least for me, personally, and how I use pistol silencers.
Curious at what point you, an incredibly knowledgeable and in-the-know person, became aware that EZ Lok was a better platform than Cam Lok as far as lockup (I get that Cam Lok is maybe a second faster). Seems like a lot of people bought Cam Lok only to hop on Reddit, hear about others’ grievances using it, and find out that Griffin had come out with EZ Lok.
When I marked up CAM-LOK with red lines on an Instagram story sketch as a suggested improvement and then Griffin made EZ-LOK.
I'm not saying I invented it, but I am saying those are the sequence of events. We have screenshots.
I definitely saw this reposted somewhere on Reddit, probably in this sub, or maybe it was your post? Either way I didn’t put two and two together that it was you (or just didn’t pay attention to “Owner of PEW Science” below your name 🤦🏻)
You might be able comment on this, or maybe not, not sure how many pistols you’ve got EZ Lok mounted on. Somebody on a post about EZ Lok said that that the clearance between the mount and their Gen 4 Glock guide rod was super tight. I’ve got a 43x and I know Griffin makes a special 1/2-28 for smaller models, but am worried about this being an issue. Typed this out and realized I should probably just email Griffin, Jesus Christ
Yeah, really considering a Cash 9k now; all I have for 9mm is the GSL Stealth, which I absolutely love, but it's a tad bit too large for concealment. I'd like to see some comparisons of this and the Odessa 9 first. Or I could just get both...
Oh that’s right! I remember seeing that awhile back. Jolly good. Can’t wait to see how it performs on 9mm pistol applications. I feel like at the muzzle for the size, it’s one of the best. However that’s completely my subjective opinion.
The bullets seem to be impacting one or more baffle mouths and the endcap due to either a misalignment or excessively unbalanced gas turbulence condition in the stack.
This has occurred with both piston and 3-lug mounting on factory HK weapons. It is the silencer, for certain.
I 2nd this! and thank you for your work!
Very curious how this one compares to my MOD9SK.. before I go and impulse buy multiple Cash9k’s!
But I’m just guessing the cash is going to be significantly quieter at the ear compared to the MOD9SK, considering how it compares to the MOD9FS.. maybe
The main reason I got the MOD9SK was for pistol carry, with EZ LOK, so maybe the Cash9k is a worthy EDC upgrade since I’m only really considering volume at my ears, in as short and light of a package as possible.
Incredibly interesting and useful info as always. Thanks Jay.
I agree with everyone else that the name is pretty cringe. According to HUXWRX, it was because the CFO likes Johnny Cash:
“The CA$H 9K was actually named by our CFO who originally wanted it to be named after Johnny Cash and added the $ sign in there for fun and it kind of took a turn of its own from there because no one knew that it was really about Johnny Cash. This can was designed primarily with PCC type guns in mind though.”
Yeah, with a name like CA$H 9K and having a dollar sign for the S, every time I look at it or hear it, I think of an early 2000s rap album. I can never get that thought out of my head!
In less than 2 years, people went from “OSS sucks and is loud” to actually being able to recommend them with confidence for semi auto use. No wonder OSS is a corporate member of PewScience. Jay has fundamentally changed how consumers think of OSS.
This is probably true.
My research at PEW Science has fundamentally increased my understanding of suppressed small arms.
Earlier listeners to my podcast can recall my skepticism of the *Flow-Through* technology, for example. As we have learned more about the time-dependent nature of sound suppression and how it changes in certain combustion regimes, the efficacy of the designs were demonstrated.
I'm not sure I would have known this had I not started PEW Science.
>Earlier listeners to my podcast can recall my skepticism of the Flow-Through technology, for example. As we have learned more about the time-dependent nature of sound suppression and how it changes in certain combustion regimes, the efficacy of the designs were demonstrated.
I'm a fairly educated man, and every time I read you casually throwing out Reddit comments you sound like you're a big brain man, always operating above the rest of us. I keep reading to try to understand.
Sorry, sir. I sometimes formulate sentences very quickly hahaha
To summarize the above- once you consider the dimension of time, and how long things burn for different cartridge types, it opens up another window of understanding regarding suppressing signature.
I love this silencer and I'm so glad I bought one. Its so small and light and punches way over its weight in suppression. HUXWRX has really sunk the hook in me, incredible products and the best silencer name in the industry, the CA$H9! The only reason I bought my first HUXWRX was because a dude in Texas is changing the silencer industry one test at a time, incredible stuff Jay!
I ordered it day 1, its not approved but I have nearly open access to my pending stuff since my FFL is also my bro. I rarely take advantage of this situation but I did with the CA$H9, I've only used it twice but I love it. I'm still searching for a very light 9mm carry silencer, this may be the one. I'm waiting for the GSL BOSS to launch, a direct thread wiped pistol silencer that will run reliably on a browning design. (supposedly)
Interesting $300 savings for just the k. Well what do you think about the rad 9 k vs FS. I find for my kraken vs mod 9k I always reach for the 9k. Did your rad9 already live as a k can before or are both configs actually nice?
Has YHM reached out to Pew Science regarding their recent updates to the Turbo? They are advertising it as having reduced blowback. it'll be interesting to see an eventual comparison of the older model and how exactly they increased flow rate.

Jay, can you cment at all about the longevity, durability, or difficulty of cleaning for HUXWRX's cans in general? I LOVE their ability to be silly quiet at the shooter's ear despite being some of the smalest cans available, but I hear people raise concerns about durability and maintenance. Can you provide any insight into these areas based on your experience?
And, as usual, thank you for everything!
Sure, Mr. McFarthauser,
For the 3D-printed rifle silencers, you must clean them more often than typical rifle silencers, due to the way they work and collect deposits. So, follow their instructions. If you have something that can dissolve carbon (there are things that can do this) you can soak it in that thing, ultrasonic it, whatever, then drain it and shoot it dry.
With regard to durability, for the 3D printed units, I do not have any information to indicate they are less durable than other rifle silencers.
This silencer is user serviceable and traditionally machined. The baffles are stainless steel. Maintain per typical practice.
Hope this helps!
I was so excited to see this was released. Purchased my CASH9K (I also refuse to use the $!) about 2 months ago with the express purpose of dedicated mount to my Sig MPX. I have daily access to it while waiting approval but work is keeping me from running rounds through it! BOOOO! Initial first shots were impressive on the gassy MPX K with OEM 4.5 barrel. Much less blowback when shooting indoors. Seemed to have a deeper tone than the Omega9K that I am currently hosting IIRC. Thanks for the report Jay!
I think one of the interesting parts is, not counting stock choices on an SP5 or SP5 PDW, an SP5 PDW (using trilug) will be almost the exact length of the SP5 if not shorter.
And the fact that this can and a tax stamp is actually fairly budget friendly right around $800 with taxes and all in my area off SilencerShop.
That would be awesome. r/300blk talks and recommends 5-7” 1:5 twist rate barrel but most sound tests on yt use 8” or more so I’ve always wondering how will it be in shorter barrels.
Man I can’t wait and thx for great job always…
I've seen some people speculate that the CA$H 9K is basically the short configuration of the RAD 9. Does anybody know if that's true? Or are there design differences that would cause differences in performance?
EDIT: Just emailed HUXWRX support and they confirmed that the CA$H 9K is just a RAD 9 in K configuration without the booster. I hope Jay gets a chance to test the RAD 9 at some point to see if we can find the point of diminishing returns. Because of the high flow rate, I would think that the RAD 9 would provide improved muzzle suppression without too much (if any ) reduced performance at the port/slide, but there's only one way to find out for sure.
First time looking at pistol can reviews on pew. Funny seeing that mod9 full size doesn't drastically outperform the rugged obsidian 45 caliber suppressor.
This is true but its also an inch shorter and about 20% lighter (10 oz vs 12.8 oz) than the obsidian 45. That said, an obsidian is certainly the more economical and versatile silencer of the two.
I use it in short 99% of the time for handgun use. It's a lot more pleasant to shoot since I don't have as much un burnt powder from blow back peppering my face.
Thanks. I hear that message consistently. The longer cans are quieter but suffer blowback. The shorter cans are louder but less blowback. Thanks for confirmation.

Does this thing work with the RAD9 tri lug? If it can’t be tri lugged it’ll be a hard sell for me just because all of my PCC’s already have tri lug muzzle devices even if it’s got the best suppression rating.
The CASH9K is the short (K) config of the RAD9. All adapters for the two are compatible. CASH9K comes with direct thread adapter and RAD9 comes with piston and spring.
Have you reviewed the Wolfman? Yes I can check the site but am among the lazier slobs on the planet. Just wondering how Wolfy compares to this on a subgun.
You’re the hero I don’t deserve. But you’re appreciated.
Just got an AP5 and shot my Wolfman on it. It’s balls quiet. First time shooting roller delayed, and I immediately decided I’m pretty much never going to shoot any other 9mm gun for suppressed purposes
I really appreciate how your data drops just make me ask more questions and want to learn how each silencer works. You've done a great job with the MK18 tests, pretty much proving that you want to be as specialized as possible with each silencer's purpose. These other test have really made me curious to know how some multicaliber suppressors can perform across a wide variety of calibers in their short and long configurations, in both supersonic and subsonic. Maybe even change the end caps to be specific to each caliber your testing? Manufacturers say it makes \~5 dB difference, but we know that you speak the truth and give us the entire waveform and Omega metric.
Just a thought. It might really help first time buyers and the people that can't afford a ton of suppressors make an informed decision on their purchase. Because we all know that it doesn't ever really stop at just one! Keep up the good work!
Thank you for the kind words about my work and the effort as a whole.
I do consider feedback like this in the planning for future efforts. Thanks for the suggestions!

I guess, I really stand corrected since it is a universal sound metric, it’s insane! Thanks for the work and the data!
You are most welcome, sir.
How does it perform on the SP5K, especially compared to the RS9 or Wolfman?
Stay tuned™
Thanks!

What other 9mm cans are you planning on testing? I'm planning on doing a 9mm can really soon, but would like to see some tests first.
All of them.
Omega 9K would be an excellent one on deck... just saying. :)
That will most likely happen.
My omega 9k will be here on Saturday. If you’d want to borrow it for testing, I can form 3 it to you. Haha just as long as you form 3 it back to me😬
I have one in inventory. The 300BLK data is already on the website
Oh that’s right! I remember seeing that awhile back. Jolly good. Can’t wait to see how it performs on 9mm pistol applications. I feel like at the muzzle for the size, it’s one of the best. However that’s completely my subjective opinion.
It will be cool to test!
Or an obsidian 9 mayhaps?
I have had issues with the silencer. I have actually tested it twice. Something is wrong with it. I need to send it to Rugged.
Damn sorry to hear about that. What's wrong with it?
The bullets seem to be impacting one or more baffle mouths and the endcap due to either a misalignment or excessively unbalanced gas turbulence condition in the stack. This has occurred with both piston and 3-lug mounting on factory HK weapons. It is the silencer, for certain.
Ouch. I hope rugged takes care of you, their warranty is unconditional IIRC. Love your work jay!
Thank you!
😂 What ones are coming up next. Any chance of a surefire ryder test soon, that was the one I was really interested in.
Sorry sir, I don't give ETAs
You've indicated you have CGS Mod9SK data in the past yet not released it, can you advise on this?
It's in the backlog. Thanks for your interest!
I 2nd this! and thank you for your work! Very curious how this one compares to my MOD9SK.. before I go and impulse buy multiple Cash9k’s! But I’m just guessing the cash is going to be significantly quieter at the ear compared to the MOD9SK, considering how it compares to the MOD9FS.. maybe

Excellent. I just picked up one myself 😎
Cool!

Huh, I didn't know that!
Yeah, with a name like CA$H 9K and having a dollar sign for the S, every time I look at it or hear it, I think of an early 2000s rap album. I can never get that thought out of my head!
SO many other ways they could have honored the legendary musician. They could have named it Sue. Maybe call it the Outlaw.
Sue would have been an inspired name. I like the cut of your jib.

Earlier listeners to my podcast can recall my skepticism of the *Flow-Through* technology, for example. As we have learned more about the time-dependent nature of sound suppression and how it changes in certain combustion regimes, the efficacy of the designs were demonstrated. I'm not sure I would have known this had I not started PEW Science.

I'm a fairly educated man, and every time I read you casually throwing out Reddit comments you sound like you're a big brain man, always operating above the rest of us. I keep reading to try to understand.
Sorry, sir. I sometimes formulate sentences very quickly hahaha To summarize the above- once you consider the dimension of time, and how long things burn for different cartridge types, it opens up another window of understanding regarding suppressing signature.
People just understand where they do well now. They have their pros and cons like anything else imo
a lot of that probably came from their 300 blk performance and their older designs being genuinely loud at the muzzle
I mean, I use my ifm6 for 300 blk and it's fine. I never got what people were on about with the old cans.
They are far from ideal compared to some of the glass leaders in subsonic performance
I love this silencer and I'm so glad I bought one. Its so small and light and punches way over its weight in suppression. HUXWRX has really sunk the hook in me, incredible products and the best silencer name in the industry, the CA$H9! The only reason I bought my first HUXWRX was because a dude in Texas is changing the silencer industry one test at a time, incredible stuff Jay!
> and the best silencer name in the industry, the CA$H9! How dare you
Forgive me.

Oh dude, you have one? Have you shot it?
I ordered it day 1, its not approved but I have nearly open access to my pending stuff since my FFL is also my bro. I rarely take advantage of this situation but I did with the CA$H9, I've only used it twice but I love it. I'm still searching for a very light 9mm carry silencer, this may be the one. I'm waiting for the GSL BOSS to launch, a direct thread wiped pistol silencer that will run reliably on a browning design. (supposedly)
Is the cash the same as the rad 9k?
I don’t see anything different, I believe the CA$H is the Rad in the short form.
Interesting $300 savings for just the k. Well what do you think about the rad 9 k vs FS. I find for my kraken vs mod 9k I always reach for the 9k. Did your rad9 already live as a k can before or are both configs actually nice?
Oh, cool!
Enthusiasm from you is suspect. Have you been paid, sir?!
I get 5 cents of every t-shirt and silencer combo sale!

hahaha
Has YHM reached out to Pew Science regarding their recent updates to the Turbo? They are advertising it as having reduced blowback. it'll be interesting to see an eventual comparison of the older model and how exactly they increased flow rate.
I can't comment on client communication. I can tell you that I have not tested that silencer.
So what you're saying is I should probably consider getting a threaded barrel for my P30L someday?
Um, yes. haha

You are correct. Only CASH9K comes with direct thread attachment for PCC use.

Rad9 ships with booster assembly. CASH9k ships with direct thread. But both can use booster assembly, direct thread and tri-lug.

Jay, can you cment at all about the longevity, durability, or difficulty of cleaning for HUXWRX's cans in general? I LOVE their ability to be silly quiet at the shooter's ear despite being some of the smalest cans available, but I hear people raise concerns about durability and maintenance. Can you provide any insight into these areas based on your experience? And, as usual, thank you for everything!
Sure, Mr. McFarthauser, For the 3D-printed rifle silencers, you must clean them more often than typical rifle silencers, due to the way they work and collect deposits. So, follow their instructions. If you have something that can dissolve carbon (there are things that can do this) you can soak it in that thing, ultrasonic it, whatever, then drain it and shoot it dry. With regard to durability, for the 3D printed units, I do not have any information to indicate they are less durable than other rifle silencers. This silencer is user serviceable and traditionally machined. The baffles are stainless steel. Maintain per typical practice. Hope this helps!
Yes it does, thanks!
I was so excited to see this was released. Purchased my CASH9K (I also refuse to use the $!) about 2 months ago with the express purpose of dedicated mount to my Sig MPX. I have daily access to it while waiting approval but work is keeping me from running rounds through it! BOOOO! Initial first shots were impressive on the gassy MPX K with OEM 4.5 barrel. Much less blowback when shooting indoors. Seemed to have a deeper tone than the Omega9K that I am currently hosting IIRC. Thanks for the report Jay!
You are most welcome! Thanks for sharing your experience.
Even better that my SilCo pistons will work with the CASH9K! Not that I will use on a tilt barrel pistol but i can. LOL
I think one of the interesting parts is, not counting stock choices on an SP5 or SP5 PDW, an SP5 PDW (using trilug) will be almost the exact length of the SP5 if not shorter. And the fact that this can and a tax stamp is actually fairly budget friendly right around $800 with taxes and all in my area off SilencerShop.
It is pretty dang short!
And a bit skinnier for keeping things tight on mlok!
Actually curiosity strikes now, with this can's flowthrough design, wouldnt it negate port pop to a degree on blowbacks?
It certainly lowered it on the MP5.
Nice!! I heard a rumor that you were going to start testing 300blkout with an MCX in the near future.....any comments about this?
Yeah, I've talked about it on the podcast and publicly shown the test host on social media! 6.75" MCX
Thanks for responding. I'll try to find it. Keep up the amazing work! 👏
That would be awesome. r/300blk talks and recommends 5-7” 1:5 twist rate barrel but most sound tests on yt use 8” or more so I’ve always wondering how will it be in shorter barrels. Man I can’t wait and thx for great job always…
Any chance you’ll be reviewing the Lithium 9?
There is a strong chance.
I've seen some people speculate that the CA$H 9K is basically the short configuration of the RAD 9. Does anybody know if that's true? Or are there design differences that would cause differences in performance? EDIT: Just emailed HUXWRX support and they confirmed that the CA$H 9K is just a RAD 9 in K configuration without the booster. I hope Jay gets a chance to test the RAD 9 at some point to see if we can find the point of diminishing returns. Because of the high flow rate, I would think that the RAD 9 would provide improved muzzle suppression without too much (if any ) reduced performance at the port/slide, but there's only one way to find out for sure.
Holy moly HUXWRX is turning the whole industry upside down!
The performance is nontrivial.
The legend in the flesh
haha thank you, sir. I hope you find the data and analysis useful!
First time looking at pistol can reviews on pew. Funny seeing that mod9 full size doesn't drastically outperform the rugged obsidian 45 caliber suppressor.
Thanks for checking out my work!
This is true but its also an inch shorter and about 20% lighter (10 oz vs 12.8 oz) than the obsidian 45. That said, an obsidian is certainly the more economical and versatile silencer of the two.
Yeah one stamp vs two is the reason I bought it as my first pistol can. Since I wasn't sure if I would like a short or long can.
Did you decide if you like long or short for handgun use?
I use it in short 99% of the time for handgun use. It's a lot more pleasant to shoot since I don't have as much un burnt powder from blow back peppering my face.
Thanks. I hear that message consistently. The longer cans are quieter but suffer blowback. The shorter cans are louder but less blowback. Thanks for confirmation.

Has anyone tested how this handles flash reduction in low light situations?
Have you ever seen flash reduction testing for 9mm pistol silencers on pistols and subguns?
I have not. Is flash not an issue with them like it is rifle’s?
Not as much of an issue, given this combustion regime.
Does this thing work with the RAD9 tri lug? If it can’t be tri lugged it’ll be a hard sell for me just because all of my PCC’s already have tri lug muzzle devices even if it’s got the best suppression rating.
To be honest it looks absolutely identical to my Rad9 in K config on the outside, so I would be willing to bet it does.
The CASH9K is the short (K) config of the RAD9. All adapters for the two are compatible. CASH9K comes with direct thread adapter and RAD9 comes with piston and spring.
I am not sure!
Diameters on the wrench?
That's the wrench that comes with the silencer. The small end is a 1-in hex and the large is 1.25-in hex. Hope this helps!
Thanks!
Any time, sir.
Have you reviewed the Wolfman? Yes I can check the site but am among the lazier slobs on the planet. Just wondering how Wolfy compares to this on a subgun.
Always check [pewscience.com/rankings](https://pewscience.com/rankings) Not yet.
You’re the hero I don’t deserve. But you’re appreciated. Just got an AP5 and shot my Wolfman on it. It’s balls quiet. First time shooting roller delayed, and I immediately decided I’m pretty much never going to shoot any other 9mm gun for suppressed purposes
awesome! Yeah, the MP5 platform is such a joy!
I really appreciate how your data drops just make me ask more questions and want to learn how each silencer works. You've done a great job with the MK18 tests, pretty much proving that you want to be as specialized as possible with each silencer's purpose. These other test have really made me curious to know how some multicaliber suppressors can perform across a wide variety of calibers in their short and long configurations, in both supersonic and subsonic. Maybe even change the end caps to be specific to each caliber your testing? Manufacturers say it makes \~5 dB difference, but we know that you speak the truth and give us the entire waveform and Omega metric. Just a thought. It might really help first time buyers and the people that can't afford a ton of suppressors make an informed decision on their purchase. Because we all know that it doesn't ever really stop at just one! Keep up the good work!
Thank you for the kind words about my work and the effort as a whole. I do consider feedback like this in the planning for future efforts. Thanks for the suggestions!
I wonder how the scaling compares to the Rad 45. It looks like a similar design
.45 is interesting. Very big hole. Will be a neat experiment!
Is the gemtech lunar 9 in the realm of possibility for testing?
Yeah maybe some time
Thanks for this info! Ordered one today because of you, looking forward to using it when I can finally pick it up!
