I have nothing against .40, .45, .357, etc. But I know two instructors that carry smaller calibers. One carries a ,22 Mag Ruger LCR, and the other a Bersa Thunder .380. I also meet quite a few people at the range that use .22 mag, .32 acp, 380 acp, 9mm and .38 for carry. Now seeing this I really have to wonder if their are really as many people carrying larger calibers as some seem to think? Since most gun fights happen at 10 feet or less with maybe 15 feet being the distance sometimes. How big of a caliber do you really need? It is all about shot placement no matter what caliber you use. And a .22 mag, .32 acp, or .380 acp in center mass can do plenty damage. Plus the fact that you can get follow up shots off faster. I'm beginning to believe the larger calibers have a place for wild hogs, bear, etc. With smaller calibers dominating CC in society.
