Key performance updates include a long, lightened 3-hole trigger with an overtravel screw, a Commander/rowel-style hammer, and a full-length guide rod with a hex-head plug. Control surfaces are thoughtfully finished, with a checkered magazine release and single-side thumb safety paired with a grip safety for classic 1911 operation.
The slide is cut with rear vertical serrations and port windows that complement the Magna-ported, ported barrel. Sights are fixed and practical: a dovetailed front blade with a white insert and a square-notch rear retained by a set screw, both set into dovetails.
The two-tone refinish presents a matte black slide with brushed flats over a matte silver/gray steel frame, accented by polished stainless steel hardware. Grips are checkered walnut with gold Colt medallions, maintaining a traditional Colt look with enhanced detail.
This is a single-action, short-recoil, full-size 1911 with a 5 in barrel and single-stack 7+1 capacity. It retains classic Series '70 and Government Model rollmarks with the Hartford address, and the included magazines have floorplates marked "COLT .45 AUTO."
Built in the USA and configured in Pre-Series 80 form without a firing-pin safety, this Government Model offers the smooth, traditional Series '70 pattern many enthusiasts prefer, matched to tasteful custom work and a clean overall presentation.
