If you want pocket carry, just be sure you actually try drawing the gun you choose from the pocket before buying it. That's why I like the S&W 642.

I have a Kahr PM9 9mm that I cannot draw from the pocket. The butt of the slide hangs up on the front pockets. When I want to carry it, I use a SmartCarry holster which I have no complaints about. I just prefer the pocket carry instead.

Since you very specifically asked about the S&W 638, I didn't vote.
But I do carry a S&W model 642 .38 spec. in an Uncle Mikes pocket holster.
