Forged construction sets this pistol apart. Both the frame and slide are machined from forged carbon steel, providing superior durability compared with cast alternatives. The Black Cerakote finish adds corrosion resistance while maintaining a low-glare appearance.
The 5-inch cold-hammer-forged stainless barrel enhances longevity and accuracy. Series 70 internals avoid the added levers of Series 80 systems, giving a crisp single-action trigger that breaks cleanly thanks to its lightweight, skeletonized design.
Forward and rear cocking serrations offer confident slide manipulation. An undercut trigger guard, extended beavertail with memory bump, and beveled magazine well improve control and reload speed without altering the classic 1911 profile.
Novak-cut three-dot sights come dovetailed front and rear, allowing straightforward upgrades if desired. Manual thumb and grip safeties, plus a skeletonized commander-style hammer, stay faithful to proven 1911 ergonomics while catering to modern shooters.
