I thought about a caliber kit for my Glock.
I think it's really important to have an accurate conversion kit. If I get a conversion kit for my Glock and I'm doing everything right but the kit is putting holes all over the paper than I'm not getting good feedback for proper technique.
I've heard different things about the Advantage Arms kit as far as accuracy.
I guess there is some training that I could do with a mediocre kit, and save a little money but it seems like I'd either be better off doing it with a quality .22 pistol or just practicing in 9mm.
