The accompanying factory letter states that this "pistol was an experimental pistol kept by the Colt factory without caliber markings on the barrel breech." The letter confirms the 5 inch barrel in 10 mm, lack of caliber marking on the barrel, stainless steel finish, and black rubber pebble grain wraparound grips with Delta medallions. It was released from the factory in 2008. The "X" suffix serial number appears on the right side of the frame.

Very fine, showing a number of minor scratches and discoloration around the grip. The grips are excellent with pebble grain remaining crisp. Mechanically excellent.
