How’s the recoil? Ever shot heavy loads? Pretty accurate?
Very accurate and recoil is very manageable. I shoot my G17 better, but I think it is because the bigger grip / frame and my hands. I run 15 round magazines which adds a little weight (5 more rounds). For a compact single stack, 15+1 is pretty awesome....damnnnnnnn our state for not allowing us to buy these mags now!!

I have shot:
Hornady American Gunner 124 grain.....Shot great and is cheap.
Hornady Critical Duty +P 124 grain......Shot great
Hornady Critical Duty 135gr.......Shot great
Sig Sauer V Crown 124 gr..........Shot great
Federal 147 grain self defense......Shot fine, didn't group as good as the 124 grain stuff. This could of been me as it had significantly more recoil.
I currenly use 124 grain bullets because they shoot the best. I also reload 124 grain plated bullets for the range, so keeping it all the same just makes sense.
