I agree that buying guns as investments is pretty iffy. Buy something you can shoot and enjoy but take care of it. Long term, Colts have an appeal that most manufacturers don't have. That doesn't mean its the best 1911 out there for that price but Colt is making good guns right now. I would stay away from the highly stylized commemorative models as a lot of collectors don't care for them. Some of the "plainer" commemorative models like the the centennial models seem to keep their appeal.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
