Precise Dimensions For A Match-Grade Fit That Gives Superb Accuracy
Fully machined single stack receiver is ready for the slide, barrel, and fire-control components of your choice to build a rugged, precision-shooting competition, combat, or carry pistol. Gives you the high quality of STI’s 2011 competition frames in a traditional, all-metal package with the popular enhancements you expect on high-performance custom 1911s. Machined to precise tolerances from high-quality 4140 carbon steel, then heat-treated to Rc 28-32 for exceptional wear resistance. Bead blasted to produce a smooth, non-reflective surface ready for the finish of your choice. Rails are cut slightly oversized, ready for honing to a tight, smooth, slop-free slide-to-frame fit to help ensure best accuracy. Holes for all pins and controls are precisely located, with a .250" tang radius to accommodate a beavertail grip safety. Available in two models, both with a standard dust cover. Standard model is machined from a high-grade investment casting and has a smooth, plain, front strap with a rounded, undercut triggerguard, and a Wilson/Nowlin-style feed ramp. Forged model is machined from a forged billet and has a straight, rounded triggerguard, and a standard ramp. Available with a plain, uncheckered front strap, or with 30 lpi checkering. Master model is investment cast and features a squared, undercut triggerguard, a cut to accept a barrel with Wilson/Nowlin feedramp, and a squared-off dustcover that extends the full length of a 5" slide for extra weight up front.
