Yet another vote for Colt. Colt has indeed had QC issues in the past, but presently, things seem to be going well. My 5" Colt pistols have been reliable. I tried three Kimbers, and all took minor to major work to be made reliable. Kimber will never get another dime from me.
Presently, I must use a DA .40 duty pistol, so my 1911 days are largely in the past, though retirement may change that. I kept my Les Baer Thunder Ranch Special, and let the other 1911s go. Of course, Les Baer is above the price range being discussed in this thread, but the way Baer pistols' frames are sculpted, where the trigger guard meets the front strap, makes all other 1911s feel clumsy to me now. I am spoiled.
