Pocket guns... Had a few before my unfortunate boating accident:
Taurus PT22 - had 2 when they first came out. Both broke. Taurus did me right. I'd like to check out one of the new poly ones as they are much better, by all accounts, then the older models. They were fun to shoot and I still have several magazines and holsters. Would by a new poly if there was ever going to be 22LR ammo available...
S&W 2214 - great little gun. Works with Model 41/46 mags too. Love the ambi mag release in the center of the grip. Very hard to find. Large grin factor shooting this one.
Beretta 21A - even better than the PT22 as it is SA/DA. Seems less picky on ammo as well. Very fun.
P64 - beefy for pocket but still small. Nasty trigger pull. Some people claim it has the nastiest recoil they've ever felt. I don't think so. Not so much fun to shoot.
AMT Backup 38 Super - yes, it is pocketable. Trigger pull makes the P64 seem like nothing - nearly impossible. Best used as brass knuckles. Or hurl it as a projectile itself. Not fun to shoot.
Taurus 738 - lightweight, easy trigger pull, manageable recoil. As much as I'd like to bash this one, zero FTF, FTE makes it a top choice for EDC. Fun to shoot too.
Taurus 856 HyLite - magnesium 6 shot 38 Special. Probably in my pocket more than anything else. 20% more firepower than a 5 shot snubbie. Did I mention light? Fun to shoot.
Taurus 94ULSS - 9 shots of 22LR in a snub revolver package, great for certain situations. Not much lighter than the non-UltraLite model so go with the steel one if cost is an issue. And a blast to shoot after getting the trigger "broken in".
