Per the Front Sight philosophy "Any gun will do if you will do". You can make it work, but I prefer my P220ST in .45.So, I keep going back and forth. I like carrying my Sig Ultra in 45. Sometimes, it's a little awkward depending on clothing and even places I frequent. I like the ease of the pocket carry .380 but is it really sufficient to stop a threat? Thoughts please.
Handguns chambered in .380 ACP are small, compact, and generally easy to carry. Unfortunately, testing has shown that they offer inadequate performance for self-defense and for law enforcement use whether on duty as a back-up weapon or for off duty carry. The terminal performance of .380 ACP JHP's is often erratic, with inadequate penetration and inconsistent expansion being common problems, while .380 ACP FMJ's offer adequate penetration, but no expansion. All of the .380 ACP JHP loads we have tested, including CorBon, Hornady, Federal, Remington, Speer, and Winchester exhibited inconsistent, unacceptable terminal performance for law enforcement back-up and off duty self-defense use due to inadequate penetration or inadequate expansion. Stick with FMJ for .380 ACP or better yet, don't use it at all. The use of .380 ACP and smaller caliber weapons is really not recommended for LE use and many savvy agencies prohibit them.
