WHICH pocket needs to be considered first. if it's a coat pocket on a parka you might get away with a Glock 19 or 1911 officer's model. On the other hand a Colt mustang or Ruger LC9 will print in a front jeans pocket, at least when you take the first step--and if you stuff a 642 in there, Mae West will be asking if you're happy to see her.
I wear blue jeans. dress pants or sweat pants. I've never been called out for carrying. It may be because of the type pocket holster dunno. I like the revolver. I have zero regrets. I have shot the LCP. It's way to small for my hands big hands. I have the larger grips on my dash 3. It fill's my hand nicely.
