The 40 S&W is not my favorite handgun cartridge, that distinction goes to the 45acp and the 38 special. It's not my favorite compact pistol round, that is the 380 for me. It does, however, want me to like it, and to be honest, I do want to like it. It is the preferred round of my brother and nephew. It was available in the past drought when nothing else was. It is also a very good performing round. My issue with it is first, is its snappy recoil. To be fair, I have never shot it out of a full size handgun, just compacts. But a few hundred rounds through it and my wrist would hurt for days. My second issue is I just really could not quit worrying about KB's. It's a cartridge loaded on the edge. It's intended configuration with a 180 grain bullet just takes up too much cartridge space. Maybe a little bullet set back from contact with the feed ramp, and a safe cartridge becomes an overload. While I have seen the after effects of several KB's, I have only actually been present when a KB happened once. It was a 40 (not a Glock). I'm thinking about getting another 40S&W. If for no other reason than just to have one. A full size. Taurus PT840, Bersa Thunder 40 HC (all metal) or the HI Point JCP. One of these might not torque so much. I am also thinking about lighter bullets, 155 or 165 grain. I know, they recoil more than the 180's, but this is due to factory 180's being downloaded a bit due to safety concerns (my opinion). But the bullet does take up less room in the case and thus will give a little better margin of error. I'm not sure yet if I will get one, and if I do it will still not be my favorite cartridge. Two of the three handguns I mentioned are also chambered in 45 (the Bersa Thunder only chambers the 45 in the UC model) and nobody can have too many 45's! But it would be nice to have another option just in case.
