Winter time > HP's or FMJ's in your carry piece.?

[WarPig1976]

Now that colder weather is on the way here in Pennsylvania I change over to FMJ ammo. I carry a S&W bodyguard in .380 because its easy to conceal at work. I figure the FMJ will penetrate several layers of clothing and still have enough energy to do its work. I have a concern HP'S will clog up and not expand/penetrate. I do this in all my carry guns .45,.40,.9mm.
Anybody else make changes with the different seasons.?

Never thought that about that scenario. I use a Body Guard also that has a laser and shoots 38Special HPs!
Round of choice is the Pow'R Ball that has Polymer Ball capped cartridge. States that it will not clog up with clothing and will penetrate a winshield and thin metal. Never tested it though.

I carry the semiauto version, mine has built in laser too but it tends to drift off after one mag.
The thing with these mouse guns is the short barrel, HP's need velocity to expand as designed, throw a leather jacket,hoody,shirt,long johns, And a rib in there with a .380 and I start having doubts. I would go bigger but carrying at work is....frowned upon.
Pow'R ball and Hornaday's critical defense are definitely an improvement in HP bullet design.

when I carry it is a PTa3 Keltec in .380. FMJ. If I use it, the range will be 12" to the gut of the aggressor. Three rounds expended, three rounds left for who ever. I keep it simple and reliable. I won't miss.

I would be VERY concerned with over penetration with a FMJ. Remember you are responsible and liable for every round. If you are worried about Carhart jackets and such a +P round may be what you need if your pistol can handle them. Just my .02, I would never carry FMJ
