I don't get the concealed carry gun idea. If I am going to carry a gun I want everyone to see it. That way they know I have a gun and if I am displaying it then I probably know how to use it. Seems to be a mutual destruction theory thing isn't it?
You carry concealed because if I'm a bad guy and I rob a joint and I see you wearing a gun, guess who the first person I shoot is gonna be....YOU, and then any guy wearing a fanny pack.
I'm another fan of glocks, but right now my favorite is the S&W M&P9. They also make the .40 and .45. For me, I like the point of aim of the 1911's, and the M&P is very much like the 1911 point of aim. They also have the inter-changeable backstraps so you can adjust it to fit you hand. I've had my M&P for about two months now, about 2000 rnds down the tube (including 1300 rnds in a two day class) and no malfunctions.
