pocket .45's don't exist and if they did, they'd be so slow for repeat hits as to be pointless, lkke 357 airweights. The lighter variants of the pocket 9 and .38 snub are very slow for repeat hits, except in strong expert hands, with special loads. you want sub .20 second repeats, not over .40 second repeats. Most shots in combat miss the enemy entirely, and most hits are poor hits, and often there are multiple attackers, so repeat hit speed is essential.
I have a love/hate relationship w my Ruger LCP. Very, very easy to carry but not fun to shoot and I advise a laser to counter speed bump sights. Amazing accuracy for the platform. I paid $269 for gun. Laser is extra.
Sig has a nice 380 w good sights as well but it is considerably more expensive and you must carry cocked n locked. Have heard its easier on recoil as well. Also very accurate.
Colt Mustang - ditto Sig
Kahr PM9 - great gun if you can afford it. CM9 - they cut some corners.
yeah, and if you had a shooting timer, you'd know that you can't get repeat hits on the chest, at a mere 10 ft, with that thing in less than 1/2 second per try. anyone can easily take a sidestep in 1/2 second, making you miss, or dive/tackle at you in 1/2 second. Also, the .45 aint all that much, with standard loads in a 5" barrel. in a 2" barrel, it's 230 grs at 650 fps, for a lousy 250 ft lbs, whoopee. might as well be a hot 380, in al locked breech like the Keltec, which is MUCH thinner and 9 ozs, and $200 in good used condition, and can get repeat hits in less than .20 second. See, the locked breech lets you use (pulled from WW ammo) 85 gr silvertips at 1200 fps, for real expansion in flesh and 270 ft lbs. the Diamondback 9mm pocket auto is 11 ozs, guys, $400 brand new.
The LCP and P3AT are too hard to shoot. I had both and went to a Sig P238 with a 7 round mag 380. It is actually a pleasure to shoot. The P938 is a 9mm and is not much bigger and would pocket carry. I use a DeSantis Super Fly. Also have a Remora for iwb. I carry a J frame revolver in 38spl +P in my pocket when I am hiking.
As in an above post I went to a 637 Smith and load it with +P Small, accurate and not hard to get a second shot off. I have one of those cheap Blackhawk pocket holsters and it's so light that you can almost forget it's there after a few minutes. And a 38 or 38+p are pretty good in my opinion anyway.
I don't think I's want to try a pocket 45 on for size. The 3" is about as small as I wan to see them and I don't see that as a pocket pistol.
