Our Assessment: Built on a Colt Series ’70 Government frame and with Colt’s slide, this pistol went to Clark’s Custom and has a number of upgrades over the standard Government model including adjustable target sights, Kart National Match barrel, and frontstrap stippling. The pistol is typical of Clark Custom’s quality with tight slide-frame fit, crisp trigger and a grip that won’t shift due to the stippling. This is a beautiful target gun that would make a great pistol for bowling-pin matches, Steel Challenge or just recreational target shooting. Please see our photos and good luck!
