I have a few 45s (Remington R1 1911, Para Expert Stainless 1911, Auto Ordinance WWII 1911, and a Kahr CW45), Now I'm looking for a carry-able 40 S&W barrel under 4", holds over 10 rounds, with some kind of external safety ei thumb safety and under $600 I've been looking around and there are a lot of choices M&P 40C, Taurus G2 24/7C, Springfield XD 40C, Glock..... the list goes on. What do you guys think? What have you carried?
