Shadow Systems MR918 Elite 9mm Semi-automatic Pistol The MR918 is custom-built from the ground up to be the ultimate multi-role lightweight Pistol. It uses the Gen4 Glock 19 as the template, and is compatible with all existing G19 holsters, mags and accessories-but it's loaded with custom components, front to back. The MR918 is built around Shadow Systems' own Multi-Role Frame, designed to provide dramatically reduced recoil and muzzle flip. The frame makes use of new manufacturing techniques to wrap more texture around the curves of the grip-so it sticks to your hand for enhanced control. The slide is machined from premium 17/4 stainless steel, and features an optics slide cut that accommodates Trijicon RMR/Holosun-pattern red dots. A specially engineered window cut reduces weight and reciprocating mass for optimal recoil impule, while front and rear slide serrations give you effortless control. The barrel is machined from 416R stainless steel, and features conventional rifling-so it's compatible with lead bullets. The spiral fluting pattern improves evacuation of debris and reduces barrel weight, making the MR918 9mm ultra-lightweight. The Pistol comes outfitted with a flat-faced polymer trigger that breaks clean after a 4-4.5 lb. trigger pull. Finished off with a solid black metal rear sight and hi-viz green outline tritium front sight, the MR918 is the ultimate lightweight multi-role Pistol.
