This is a photograph of the fabled Colt 1991A1L1. The Colt 1991A1L1 is a reworking of the original Colt M1911A1, but with a modern twist. The Colt 1991A1L1 is highly prized by collectors of the Colt 1991A1L1 guns. This particular example does not have the Colt medallions in the grip panels.
This version does not use mil-spec sights, but it does resemble the M1911 pistol in many ways. The finish is a dark blue, almost black, specialty bluing from Colt.
