Kahr in 9mm hard to beat and very easy to carry
Didn't you say you had a S&W .38 in the other thread? Seriously, that's a much better carry gun than a small pocket gun. With the right holster, you could conceal your revolver very easily, and it would be more reliable.
The money you spend on a pocket pistol would be better spent on ammo and training.
When I pocket carry (only in places like the mall where I can't OC), I have a Ruger LCP. It doesn't make an imprint (I'm also not a little ****** who wears skinny jeans though) and it's lightweight.
That said, it's a ***** to shoot.
Yep go with the J frame and some practice.
