Works great - Lone Wolf Arms Glock 22/31 9mm Luger Conversion Barrel

I used this barrel in a Glock 31 which is .357 Sig. Seeing the .357 Sig is a “hot” round, the 115gr 9mm target loads would stove pipe fairly consistent. I’m confident that changing the recoil spring would fix this if you’re dead set on shooting the light 9mm rounds. I had absolutely flawless performance shooting 124gr and 147gr. I’m very pleased. So if you plan to shoot the light stuff, buy a 9mm recoil spring, if you want to run the stock G31 spring, shoot 124gr and 147gr.
