I realize that a .380 is a marginal round for SD and does not always have the necessary penetration. Would a .380 FMJ be better for SD than a .380 hollowpoint..... so that it can penetrate deeper? I also read somewhere where it was said that in a .380 go with the FMJ...because hollowpoints in that caliber will not expand reliably.... What do you guys think? I am looking for the most effective self-defense round in a .380. (And yes... I do realize that there are more powerful calibers out there.) Thanks in advance for your words of wisdom.
