Flat mainspring housing machined from 6082-T6 aluminum helps achieve maximum weight reduction for shooters who want the advantages of a light, custom carry or competition gun. Weighs only 17 grams – over 2½ times lighter than similar flat housings made of steel. Checkered model is bead-blasted, then treated with a proprietary, black or silver hardcoat anodized finish that’s denser and more abrasion-resistant than traditional sulfuric anodizing; 20 lpi checkering improves grip and is less prone to snagging on clothing than extra-fine line patterns. Plain model is smooth without anodizing to allow custom checkering and finishing by the gunsmith.
SPECS: 6082-T6 aluminum, Checkered - hardcoat anodized, matte Black or Silver. Plain - in-the-white, unanodized. Govt - Fits Government and Commander models. Off - Fits Officers model.
