Depends on situation. Sometimes a CZ p-01 IWB. Almost always a S&W 042 right front pocket.
FWIW, it's been my experience that, except for pocket guns, barrel length has little to do with ability to CC. Thickness is the big deal. You know, brick versus pencil.
One thing I really like about pocket carry is the ability it affords to clandestinely keep my hand on the gun or even partially draw it w/o brandishing or assuming an awkward pose. I consider this an important, though seldom mentioned, advantage of pocket guns, revolver or pistol. When I see a suspicious character approaching or I'm in a parking garage, etc., the 042 is in my hand, and no one else knows it.
Also the .38 sp. is not as anemic as it once was thanks to two new rounds: Speer's 135 gr GDHP and Corbon's 110 DPX. Each fired by a snubby gives adequate penetration and 1.5 X expansion under FBI testing protocols. The Speer was developed at the request of NYPD seeking an adequate round for BUGs.
