For years I carried a S&W Model 60 Chief's Special 2" in either a pocket holster or ankle holster. Ankle holster wasn't secure enough for my liking and I know too many guys that it caused circulation issues in their leg. Later I carried a S&W 669 9mm in my pocket.
Stainless is the way to go for a BUG that will be in a pocket. I know a lot of guys that had rust problems with blued revolvers in their pocket.
The S&W "J" frame revolvers are well built and reliable.
