Shadow Systems® focused the design of their highly-innovative MR918 Combat to provide you with a modular, semi-auto pistol that delivers well-placed shots instinctively, and to always operate flawlessly. The polymer frame comes with 3 interchangeable backstraps (high, neutral, and low), which adjust the pistol's natural point of aim, by raising or lowering the muzzle so the pistol points naturally like your finger. The contoured frame utilizes a double, under-cut trigger guard and a high, extended beavertail to place the shooter's hand as close to the bore axis as possible, dramatically reducing recoil and muzzle flip. Aggressive grip texturing extends around the curves of the frame to provide a solid, non-slip hold. A removeable magwell extension speeds reloading, if so desired. The slide is machined from 17-4 stainless steel, and features front and rear directional serrations to provide optimal grip surface for loading or clearing the weapon while the shooter is under stress. Serrations are cut specifically to interfere minimally when drawing the pistol from a holster. The spiral-fluted, 416R stainless steel barrel is mated to the slide for maximum accuracy potential. The spiral barrel fluting clears debris in extreme shooting conditions, reduces barrel weight, and helps dissipate heat. The MR918 Combat semi-automatic pistol utilizes a flat-faced trigger with a proprietary trigger bar that work in unison with a TTI connector to provide a consistently clean break, with reduced take-up. A trigger safety prevents the weapon from firing unless the trigger is intentional pressed in the center, and several internal safeties prevent the weapon from firing if accidently dropped. A solid black rear sight and a green tritium front sight allow precise shot placement, as well as an index point for rapid shooting in low-light conditions. An enhanced LCI extractor with proprietary geometry reliably extracts a wide range of ammunition. The Shadow Systems MR918 Combat Semi-Auto Pistol is compatible with GLOCK® Gen4 G19 holsters and accessories. Ships with 2 high-capacity magazines.
