The particular .380 ACP rounds I carry are Hornady American Gunner XTPs, which seem to be pretty much the gold standard for .380 JHPs because they meet minimum FBI Specs in Ballistics Gel Tests.

I wouldn't carry FMJ because those things penetrate a lot more than anyone would expect. My mother once had an ND in which she accidentally shot through the living room floor with her Taurus TCP, the bullet punched straight through the hardwood floor, penetrated through galvanized aluminum furnace ducts, and was found in a considerably deep divot in the concrete floor. I'm not sure what she had loaded, but I've seen the bullet and it appeared to have been an FMJ, hard to tell for sure though because it did mushroom out.
