I have 2 pocket holsters from Ryan Grizzle leather love them they are awesome!!

PJ Holsters. He adds a small thumb tab on the holster to insure you can eject the holster from the gun, if need be.
Great guy to do business with, too!

Got a Barsony off of Amazon for a J-frame. Nylon construction. I've had it over a year; carried almost daily and it still stays put.

Vedder's Pocket Locker wors perfectly for my Smith 2.0 bodyguard. Kydex, if that matters to you, stays put in my pocket when I draw.

I used to buy most of my holsters from Vedder, never had any problem, but for some reason I got away from the brand. Starting to use them a lot again.

Vedder Pocket Locker w/ the thumb notch and the tail bent in. Stay put in the pocket, during your draw and the bent in tail helps conceal the gun in your pocket better.
