I've had several and the one I like the best is the K Rat by Palehorse holsters. It is somewhat stiff suede and stays in the pocket upon the draw, has a thumb push on top to add in the draw, it is thin and conforms to my thigh, holds the gun, but has an easy draw and conceals well. Have one for my P3AT and another for my .32 Keltec, so I can carry one on either left or right now. I've also used the belt clips, but it makes me nervous to carry a gun, with the trigger exposed.
