I usually go with my P-32 when I pocket carry, though I'm considering using my Taurus 445 for warmer weather and clothes that more roomy than jeans.
I have a Ruger LCR that works well in the pocket.
I have a Ruger SP101 that I use for this purpose exactly and I love it. I stick it between the console and the seat belt for quick access while I'm in the car. I almost always have a glock in an Uncle Mikes inside the waistband for when I go into the store, but I have slipped the SP101 into a front pocket plenty of times.
The S&W 442 and 642 would be my first pick. The new Ruger is pretty slick too. I have a S&W 638 that I picked up a few years ago for $250. That replaced a S&W 637. I carry that in a Galco COP rig and two reloads in strips when I go out unarmed. I still would love a S&W 340.
I have carried both and only reason my current CCW gun is a Sig P228 (Colt Mustang clone) is because of the small grandkids in our home every day. Normally I would pocket carry a revolver because of their shape and grip angle they are easier to draw out of pocket ready to fire.
When kids are around and could get hold of you gun, an automatic with manual safety may be a life saver. If the auto is left w/o one in the pipe on my Sig the grandson can't rack the slide to load the gun, and even with teaching kids gun safety and not to play with your gun they are kids and if they could get away with playing or looking your gun over they most likely will.
