Very interesting, thanks for the link. I was interested to see the Gold Dot and Critical Defense rounds' performance. The performance from their GD differs from what I have previously seen, having decent penetration and deformation. Maybe it's due to their test protocol. IMO bare gelatin tests are not worth the time it takes to conduct them. The link states their test protocol includes 2 layers of denim, if they would have used 4 layers I believe the results would have been much different, and more comparable to others I've seen. With time and money limited, the last few times we tested duty ammo we cut to the chase and only used the auto glass (windshield) and the 4 layer denim protocols.

Ball is about the only .380 I have seen have acceptable penetration in the denim testing. No hollowpoint, one that actually expands anyway, makes 12 inches in my experience. Like Erich and others have said the .380, while very popular, has poor terminal performance; it either expands and has insufficent penetration , or has sufficient penetration (unless it strikes significant structures in the body) and pokes a very small hole. It's best to carry a larger caliber if at all possible.
