I went through a 1911 phase and have owned and shot the snot out of guns from several top name smiths - Tibbetts, Christiansen, Tussey, C&S, Novak, etc. Calibers ranged from 9mm to .45ACP, with a 10mm and a 9x23 thrown in for good measure. None of them were more accurate or reliable than my Mk23, which was good to go right out of the box, and cheaper than any of the custom 1911s I bought.
1911 gives you a light, consistemt trigger pull that resets quickly - which is why most folks shoot them for games - IPSC, bullseye, etc. Mk23 trigger pull isn't quite as good, but very, very, good for an out of the box gun.
If you need a CCW pistol then I would get a Mk23 and a USP Compact or HK45C rather than get a custom 1911 - this way you have a CCW .45 with the HK45C as well as a tack driver, range gun, cool suppressor platform with the Mk23.
1911 customs are great weapons - but way overpriced and way overhyped IMHO.
