I have a GLOCK 23. As the other fellow posted, it is about state of the art for a concealable handgun that shoots a major caliber round. It is accurate enough for shots under fifty yards on human silouettes. I carry it while working, because I sweat a lot, and I don't want to mess up my model 19 Smith And Wesson, 4" barrel. I bought it for my concealed carry classes, figuring most people who know nothing about handguns all have someone they know who is an"expert". The "experts" all seem to be reccomending GLOCKS nowadays. I am a little lazy, and if I have to teach them to feild strip and auto, I'd as soon teach on a GLOCK. I also figure my wife could carry it. She can't pull the slide back, although she did like the huge sights. Maybe I'll get her a GLOCK 19?
When I am at church, I carry either a 4" model 19 Smith And Wesson, or a 6.5 inch 629. I am built like a barrel, so for me, when I wear a coat and tie, either of these is actually easier to conceal inside the waistband. All that really sticks above the belt is the grip, and revolver grips are slimmer that GLOCK grips. Be carefull, however, if you are a praying man. I once got under strong conviction, and went to the alter to pray. When I got up, my coat tail was clinging to the soft rubber Houge grips on my 629. Doesn't happen with the GLOCK, or the model 19's pachmeyer grips. I don't think anyone saw the gun, but I did look a little funny.
