Colt pin gun in .45 ACP build by Mr. Paul Liebenberg circa 1990. This beautiful gun, with a single port compensator, abundant hand checkering, low mount Bomar, and hard fit Barsto, is cloaked in hard chrome and shod in custom Spegels. It is (to me) a virtual masterpiece— ie one of the best guns I own. Paul is a trained industrial designer who has been a professional gun builder for over 30 years. He was a member of the World Champion South African Practical Pistol Shooting Team, NRA High Master, certified four-gun firearms instructor and professional pistol shooter who competed successfully in many disciplines in the shooting sports. Before starting Pistol Dynamics he was a pistolsmith at Pachmayr (building Combat Specials) and after that the head smith of the famed S&W Performance Center. He had a significant role in the technical development of the 40-caliber pistol cartridge that eventually became the 40 S&W we know today.
