Jim Garthwaite built me this gun over a decade ago. At the time, and now its pretty much state of the art. I purchased 2 brand new Colts-an "enhanced" Officers ACP and an enhanced Lightweight Commander and swapped the tops. I sold the bastard child for an exorbitant amount and sent Jim the parts and pieces. We settled on a ramped barrel made by my friend Fred Kart, whose shop I had previously visited. A Melange of Wilson and McCormick parts finished her up. I recently had the tritium front sight replaced with a Gold bead and had Jim install the solid trigger which I prefer. The only problem ever with this gun? A cracked firing pin stop that Jim replaced with a Caspian. Colt Series 80 parts have been (wisely) removed. NP3 makes her pretty and slick.
