I've Got a Few
Like the other fellow, I put an Lcp in a hunter "wallet" type holster in my back pocket in the morning and take it out when I hit the sack.
I often have a S&W 642 in my front pocket... Nobody has mentioned the snub's, but they make good pocket guns. I've got an LCR too, but I carry the Smith.
I've got an NAA 22 mag mini revolver in my front pocket right now.
My newest toy is a Sig P238. I bought it more because it's so darned cool than anything, it's almost too pretty to mess up carrying all of the time, but it fits the front pocket nicely... If it passes the reliability test I might make it my "Sunday go to meeting" pistol.
