Not true if you carry FMJ in a 380.
I agree with the FMJ in .380 ACP. When I had a .380 as a BUG that's what I put in it, but I sold it and went back to a .40 BUG.
Some say it has too much penetration!
Drugs are bad, mkay?
First of all, even a .380 FMJ isn't going to penetrate too far. But second of all, there is no such thing as too much penetration, with the possible exception of being on an airplane. The more penetration, the better. People who say they want to bullet to stop inside a person so that it dumps every bit of KE in the body are just wrong. I want it to go through the body as fast and as far as possible, and if it exits, so much the better. Two holes are better than one! That's twice as many places to leak from and more damage done to the body. The only reason you wouldn't want that is collateral damage behind the target, and the chances of that in almost any SD situation is very minimal (think about it, think about where you are going to be where you are likely to be involved in a SD encounter).

That's supposed to be pretty good stuff I think, but I've never tried it.
