I've owned/own handguns in .380, .38, 9mm, .38, .357, .40, and .45. I have to say that .40 is my favorite caliber to shoot. I find myself to be more accurate with a handgun that has more kick/snap in the recoil than tamer calibers. I don't know if I concentrate more because of the increase in recoil, but that's how it works out. While it seems that a lot of people are getting rid of their .40 cal firearms, and do not want to shoot .40 anymore, I embrace the caliber, and will probably work my way down to that caliber exclusively in the future. The wife is one who thinks that the .40 cal is too snappy. Yet, she has an SP101, so go figure. I enjoy more of a challenge when shooting handguns. I have never owned a .22 pistol. I know that they can help with trigger training for sure, but I never went that route. I save that caliber for rifles. Anybody else for .40 cal.???????????????
