I carry a revolver. A J-frame .38special. It has only 5 shots, but I trust it. Why? I've had 3 semi-auto pistols that regularly jammed. My first handgun, a Star Model B Super, was repaired by smith to work perfectly. My second handgun, was a EAA Witness polymer in .40 S&W. It jammed like a fiend. 300rds down the pipe and still jams. When I decided to get my CCW, I bought a keltec p-32. It had a problem with light strikes. I needed a pocket carry handgun for CCW. I ended up handling a S&W j-frame snub. It fit perfectly, and it was light weight. I've put nearly 400rds through it without a single problem or malfunction. I trust it. Its only got 5 shots, but it hasn't failed me once. Every semi-auto I've owned has either stovepiped or jammed at least once. Even my beloved Makarov. I know that its only 5rds, but I trust it. It will shoot those 5rds regardless if I hit or miss. Whether there are 10 attackers or just 1. If it fails me when I need it, I am dead regardless if it was a semi-auto or a revolver.
I am not opposed to semi-auto pistols. I carry them on occasion. I want to find some that I like and would carry more. I love all guns. I just think that they're all useful in their own way. I think a person armed with a revolver is not exactly something to sneeze at. Some folks will and do, and they do so at their peril. We all stand more of a chance of dying of a puny .22lr than we do any caliber bigger.
