I have its twin, but mine has a birthmark. My slide has a "Colt Dome" with the poney on top, and the lettering says Colt Custom 45. It has a SS barrel and SS bushing. Needs a bushing wrench to remove. Has the solid trigger and the serial number is CCS####. They are custom shop jobs. The rear sight is a HEINIE with the lock-down screw. Trigger is very light after small amount of takeup. Shoots 2" @ 25yds if I do my part with factory Fed 230g ball. Buy it, you will like it.
