The frame is the heart of the pistol and the key to controllability when shooting. Their design works to get the frame ultra-low in the hand, with an extended, upswept beavertail and a dramatic trigger guard undercut. The frame features wrap-around texture which is aggressive enough to give a positive grip in all weather without being uncomfortable for daily carry. Shadow Systems frames incorporate a textured recoil control ledge for the support-hand thumb to engage, which vastly reduces muzzle rise between shots and allows for faster follow-up shots. The frames feature the groundbreaking Shadow Systems NPOA backstrap system, which fundamentally changing the grip angle of the gun to meet the shooter's natural point of aim. It's not about comfort. It's not about small, medium, or large. It's about getting fight stopping hits at close range, under stress, whether you see the sights or not. Shadow Systems frames have a generous internal magwell and also come with a removable magazine well, mounting, hardware, and tool, for those who want even faster reloads. Other frame features include a high-traction magazine release button, an enhanced slide-lever curtain, and compatibility with existing holsters.
