Oddly enough, I found my J-frame is less identifiable in my pants pocket than an auto of the same size. It seems the cylinder breaks up the outline enough that it doesn't shout "gun." It looks more like I've just got some junk in my pocket. (This, with both guns naked, no "pocket holster.")
For coat pocket carry in cold weather, I carry the J-frame in my right pocket, but I had the same problem with it turning upside down that someone else mentioned.
So I made a prototype sleeve for it out of cardboard, as shown, and that worked like a charm. I was going to cut the same thing out of leather, but stupid as it looks, after the first one wore out, I just made another one out of cardboard. The second one is still going strong, and if I should have to fire from my pocket (G-d forbid), I won't be ruining a carefully hand-crafted leather sleeve, just the coat itself.
So guess I'll just keep making "prototypes" out of cardboard. Hell, they last at least a season's worth of cold weather before needing replacement, and it takes all of 15 minutes and a foot of duct tape, so....
