Trying to get something out of a pocket quickly is a hit-or-miss proposition.
My preferred pocket carry is my S&W Model 60 in an Uncle Mike’s holster, with the holster holding the grip outside of the pocket. Covered with a shirt, it is very hard to see & very easy to get to. If feeling uncomfortable, I can rest my hands on my pockets, which also allows me to take hold of my gun while looking like I’m just a little tense.
