My present carry is a S&W M&P 9mm. I also use a larger .40 at times. Wear Western clothes and usually have a vest on. In winter I use my down jacket or ranch coat. I finally got a DeSantis leather holster (about $75. shipped) which fits like a glove! Can't underestimate the use of a quality holster for CC.
Whenever I modify my attire, I always double-check in mirror. The bottom of my holster is always at least 1-2" below the "tail" of my vest, or jacket. I'm very comfortable with CC. I know which movements to make or not make. I don't reach high on a shelf for things. In a restaurant, I sit in a booth with gun side opposite the outside of the booth (and, position the gun side to a side wall if at a table.) Rather than bend over, I'll squat down to pick something up. I always use the crapper before I go somewhere.
More than once I have been carrying and have passed one our local deputies or Sheriff in a store. No problem. No panic. I just always speak, and assume an innocent, "poker face" affect and assume I am within my rights to CC.
I have developed some very incidental ways to check my printing and/or wallet for that matter. Doesn't hurt anything to start "scratching an itch" if needed...lol. My gun side pockets don't have anything in them I must get; thus, no fear of accidental printing of revealing if I need something: that's what other pockets are for.
Of course, I'd never carry in any place where a handgun is prohibited...
Oh, yeah...I've been member of NRA for many years...
