If you are looking for a more "modern" 1911, look at an XSE version. They are "enhanced" with undercut trigger guard, upswept beaver tail grip safety, skeleton hammer, three-hole alumnium trigger , Novak sights and front slide serrations.
BTW, Colt just dropped XSE's from their line up (literally last week), so there will not be new ones produced any longer. You can still pick up a brand new one online or probably at the Indy 1500 this weekend. Check out ZX Guns, they probably still have them.
