Shadow Systems MR920L Elite Longslide 9mm Semi-automatic Pistol The MR920L 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 existing G19 mags and accessories-but it's loaded with custom components, front to back. This Longslide model takes the accuracy and performance to a whole new level with a 0.5 inch longer sight radius compared to the standard MR920 Elite. The extra slide length also helps eliminate some of the upward snap of its smaller cousin, helping to keep you on-target for faster follow-up shots. The MR920L 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 Shadow Systems's awesome new optics mounting technology (more on that below). A specially engineered window cut reduces weight and reciprocating mass for optimal recoil impulse, while front, rear, and top 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 MR920L 9mm ultra-lightweight. Muzzle threading allows for the use of a suppressor or brake, too. 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 MR920L is the ultimate lightweight multi-role Pistol.
