Kimber makes small 1911 style .45's also you could look into the XD's they make a nice compact I personally would buy a XD over a Glock but thats just me. I have a friend that carries the Karr Arms .45 and loves it.
Check out the Glock 36. Compact, light, accurate and goes Bang every time I pull the trigger. It's not a 1911, but for CC it is great. Kahr makes a .45 that is slim and easy to carry too. If you can find a 1911 with a Commander slide on an Officer's frame, they make great carry pistols too. The Para LTC is a close clone of this size. If you have the cash, the new Bill Wilson carry pistol will do very well.
