"I pocket carry my 642 without a holster. I tried ever way from Sunday to get it to fire (empty of course). Just don't see it. Not with a 642 anyway."
I carry an SP101 everyday that way everyday, but revolvers are a different animal and are not something carried "cocked" whereas most semi's will be carried cocked, because no one wants to draw and then rack the slide while your threat waits for you to get prepared.
I ride four wheelers/ATV's like that all the time! I don't worry about an accidental discharge, but with my Glock I ALWAYS have a holster and a secure one at that.
