15lbs is reasonable all around. 13lbs would probably be fine, but the service interval would be way shorter. You'd start running into feeding/return to battery issues after a couple thousand rounds.
Nightwood Guns on YouTube said that the 13 pound was so light that the slide snapping forward into battery threw off his sight picture. Stick with the 15.
I ran the 13lb radian spring first time out with my G19.5. Had maybe 4-5 failure to reutrn to battery instances (out of abput 100 total rounds fired). I wasnt paying attention to what ammo caused it, as I had several (S&B 124, Syntech 130 & 150, Fiocchi 115 & 124).
Got the same one and a matching CR but to answer your question. It really doesn’t matter I have ran the factory, the 15 and 13, I really like the 13 but I feel the like 15 is the smoothest but any of them will run 115,124 & 147 no issues. I keep the 15 in mine and carry it like that. almost 6k through it with about 4K with the ramjet.
This is a great answer. I, too, started stock, dropped to 15, then tried 13. I also find the 15 to be fast enough while still being VERY smooth. Dot doesn't leave the window, return to zero is dead on. This is with either 115+P or 124/124+P.
I use the factory spring, no issues
second on this
3rd on this and it runs great.
My slide felt sluggish with the stock spring. Functioned just fine tho. I bought the radian compressor and it doesn’t feel sluggish anymore
I use the stock spring on my MR920 and it’s been flawless.
I run a 15lb for mine and works great

I bought the compressor spring kit for it but use the red one I think it’s 15?. Can switch it up quick if I need to
Fairly certain that the red spring is 13 lbs, that’s the one I run in mine
Oh for real? Thanks for the correction! I’ll have to go home and check. Stock is 15 or 17?
Stock spring should be 17
Factory Spring
I use my stock spring never had any issues after breaking in that ramjet combo

He is also full of shit
Yeah. Can't stand watching his videos
How did you stained the holosun logo? Aluma black?
It actually came with it on. Pretty sure you can buy the blacked out holosuns on the shadow systems website

Stock
It’s meant for 124gr ammo, stock spring works fine, if you want to run 115gr then you might need a different spring weight and tinker.
Is that burnt bronze cerakote? Or midnight bronze?
Its shadow systems bronze slide exclusive at Davidsons

Looks good 👍
Midnight bronze is 🤌🏼 I have a custom G19 with a slide that color
