Long-lived thread.
When it comes right down to it ... (just my own thoughts) ...
The .380 ACP is never going to be a .38 S&W Special.
The .38 Spl does offer some newer bullet designs, and some of the current +P loads have been tweaked by the makers to offer some potential for "performance" when fired from the 2" snubs.
The .380 is never going equal the .38 Spl when it comes to bullet weight, though. That may well matter to some folks. It does to me, but I'll still pocket one of my LCP's over the thicker J's, depending on my desires and clothing at the moment.
If you feel the absolute "need" to try and bootstrap the .380 into something "more potent", by using some hot-rodded load made by one of the custom ammo makers? Not my problem. Does the maker of your .380 recommend and approve of using it? Since there isn't a SAAMI rating for a "+P" load in .380, you may be on your own if you damage your little .380 by running hot loads in it that aren't approved by the maker of the actual gun.
Some folks look for their diminutive .380's to reach the current "performance criteria" used for LE duty handgun ammunition in various ballistic testing. Well, if the little .380 could run that gauntlet and produce the same "ballistic performance", don't you suppose the major LE/Gov agencies would've accepted the .380 ACP as a viable alternative to the common duty/service handgun calibers?
I tend to look at the .380 as being no more than it is, meaning -
for me - a really diminutive pocketable retirement CCW option for those situations when I decide I (hopefully) won't require the potential penetration offered by my assorted 9's, .40's, .45's, .357's or even my .38's.
Other .380 owners seem to prefer the non-expanding ball loads for their carry .380's. I prefer to carry one or another of the more modern JHP's that may offer some potential for a little expansion (or which might become "ball" loads if they don't expand).
I'd carry ball loads if that was all I had available for my LCP's, but I carry JHP's because I can.
I've seen a couple instances where .380 ball loads really perforated some building materials. In one of them a ball bullet passed through something hanging on an inside wall, then passed through the wall (adjacent to an exterior door frame), and then hit someone outside in a parking lot, in the spine, which resulted in making that person a paraplegic.
I think I'll pocket a LCP in a little while when I have to go into town ... because the very deep pockets of the cargo shorts I'm going to wear typically positions one of my J-frame snubs
exactly over a spot on my thigh which creates a hot spot very quickly, and which starts to throb down to my knee. Using the cargo pocket lets the snub & its holster tip over, which can let the gun slip from the holster, and it also constantly bangs against the side of my knee, creating annoying pain of another sort. (No, I prefer not to carry IWB/AIWB, as that still rubs, when seated, against a spot in the inguinal area which can become tender.)
I get the context and meaning of the "comforting versus comfortable" discussion, but there's no reason for me to intentionally expose myself to avoidable discomfort if I'm running around in less risk environments. If I actually expected I'd find myself in a higher risk environment, I'd either not go there (first choice), or I'd belt on one of my larger pistols.
Everybody's gotta suit themselves, right? (And for the carefully considered reasons which make sense to them, presumably.

)
Best regards, everyone.
