After I initially got my CCW permit, the first gun I carried was a S&W Model 642. I carried it in a pocket holster in my right rear pocket. Four years later when I renewed my permit, I had become more tolerant of heavier, bigger guns and carried a S&W 3913, OWB. I carried that for 5 more years. Years later, now, I routinely carry a Sig 220, 45 ACP or a full sized 1911, 45 ACP, OWB. In my old age I've only become more tolerant of one thing: larger, heavier handguns on my belt.
I'm not much of a fan of the J-Frame, but do occasionally tote one when I can't contrive to carry something larger, or on the infrequent occasions a back-up seems expedient.
This mid-1980s Smith & Wesson Model 649 .38 Special suits me best. I prefer the weight of all-steel construction and the no-snag configuration of the old Bodyguard design gives the best of both worlds, single-action and double-action trigger capabilities.
just got back from the range to try a Sig p229 40 cal that I acquired and have never shot. OK shooting gun , very controllable. While there I decided I better try my 60, that I haven't shot since it came back from S&W some time ago. What a BEAST! shooting my carry rounds Remington 125 semi-jacketed hollow points, the old original full power loads. PUNISHING!
S&W stainless/lightweight 642 in a Stoner Leather Pocket holster carried in strong side front pocket. The holster isn't necessary to facilitate a quick draw, but it does keep the butt positioned for a quick draw. The primary reason I use a pocket holster is as an added safety since the trigger is covered by the holster. Carry 125 grain hollowpoint +P+ loads.
