Ever since I got back from revolver round up this year I've been carrying a 640 Pro AIWB with two 6 rnd speed strips in my back left pants pocket (I'm left handed) since I guess I am a optimist.... I like to toss the 642 in a simply rugged pocket holster as well, I like the "tactic" of standing around talking to people non threateningly with my left hand nonchalantly in my pants pocket... Working a gun counter for my buddy part time since I retired from active duty makes this useful every so often.
