Exactly Bigfoot. Annihilator I have not done ballistic tests on .380's. But I have been around some tests and Ballistic Gel is a mess and it STINKS. Lucky Gunner is nice enough to provide a lot of info. If you look at the .380, basically the hollow points that open up start to show lessor degrees of penetration some tragically shallow, but with expanded bullets the marketing department love to photograph. Add a leather jacket and a flannel shirt and long johns in the winter, and it would only be worse. Gel is interesting, and it allows one to compare ammo performance against each other in a controlled fashion, but it is not anything like shooting humans. I stand by my original stance. In lessor calibers, sub .38 Special, penetration is key to stopping the threat. And with that in mind, I want to add an extra hole with the .32 acp over the .380 acp. And I also think that unless there a physical reason for only carrying a small handgun, one should start with a .38 Special in a Smith and Wesson J frame or the much lamented and long discontinued Colt Detective Special/Cobra/Agent/Police Positive. The front sight is MUCH thicker than the J Frames, so I prefer the Colts. You noticed the Police Positive I snuck in there. Worthy of a whole new thread, I will get to that!
