I carry a Para Ordnance P14-45. It's a 14 shot version of the 1911. I dearly love that weapon. The larger grip frame fits my hand perfectly. That being said, while I am a firm believer in the gospel of John Moses Browning, I also understand that to carry his finest design, one must train to the point where the weapon is a natural part of your body and mind. A single action weapon requires that you be intimate with it. You must train until the "manual of arms" is better than second nature. You should be able to draw and cock the weapon in an instant, while keeping your finger OFF the trigger, as a cocked 1911 is begging to be fired. The 1911 is NOT designed to hold anyone at gunpoint, it is designed to kill people, as quickly and efficiently as possible.
I recently requalified with mine (we have to fire 50 shots) all but two were 9 ring or better, and all but 6 were 10 ring.
I strongly suggest you consider a Sig P220 if you like 45ACP (and I certainly do, I'm NOT a fan of 9MM or 40 Short & Weak). The Sig P220 has a feel that 90% of 1911 people find acceptable, if not downright lovely. It can be had in many variations, many of which are EXCELLENT carry weapons. They are available with a double action first shot, a very good idea for a carry weapon.
