Shadow Systems MR920 9x19mm, Elite, FDE, Spiral Threaded Black Barrel

The MR920 is a feature-packed, compact-sized pistol that is designed to work with existing G19 holsters, magazines, and gear.

The MR920’s frame features configurable ergonomics. Interchangeable backstraps allow shooters to adjust the grip angle to fit their natural point of aim. An extended beavertail and aggressive trigger guard undercut work to dramatically reduce recoil and increase controllability. The frame’s wrap-around grip texture is aggressive enough to keep the gun firmly in the shooter’s grip without being uncomfortable for daily wear.

The MR920 slide has a thinned profile at grasping locations and directional serrations in the front and rear (as well as topside on some models) for easy manipulation under stress.

The match-grade barrel is conventionally rifled and spiral-fluted to improve evacuation of debris. MR920s are also available with threaded barrels, for those departments that allow the use of muzzle devices.

The drop-safe, flat-faced aluminum trigger has a 4.5-5.0 lbs trigger pull and a crisp, tactile reset. Optic cut models allow shooters to mount the mini red dot optic of their choosing. The optic cut on the MR920 can accommodate most major brands of RDS optics directly mounted to the slide, without intervening plates or adapters.*

THE SHADOW SYSTEMS FRAME

The frame is the heart of the pistol and the key to controllability when shooting. Our 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.

Our frames feature the groundbreaking Shadow Systems NPOA backstrap system, which fundamentally changes 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.

MULTI-FOOTPRINT OPTIC CUT

Shadow System pistols have the option of the patent-pending multi-footprint optic cut. This optic cut is the only one in the industry to allow for the mounting of most brands of red dot optics directly to the slide without the need for intervening plates or adapters. The optic cut mounts the optic low in the slide, with the longest and strongest screws available on the market. Tested optic brands include: Trijicon, Vortex, Leupold, Holosun, SIG, Swampfox, TruGlo, Shield. We are continuing to test optics in our mounting system; for an updated list of approved optics for our pistols, see the chart here.

The optic can be mounted low enough to allow for a lower 1/3 co-witness with the factory sights. Factory sights on Shadow Systems pistols feature a bright green tritium night sight front with a blacked out rear sight to allow faster sight picture under stress.

SLIDES

Shadow Systems slides are designed to minimize recoil and maximize control and comfort. Machined from 17-4 stainless steel, Shadow slides feature directional serrations. The directional nature of the serrations provides an aggressive grasping surface when manipulating the slide, but vastly reduces friction when coming out of the holster. These serrations are seated in shallow pockets on the slide making the slide feel thinner and easier to grasp. Shadow slides are profiled to be more comfortable for IWB carry, eliminating the feeling of the slide digging into the shooter’s side when holstered.

The difference between Combat and Elite pistol models is solely in the slide features. Combat pistol models feature directional serrations in the front and rear. Combat models can be configured with or without the optic cut. Elite slides are machined with directional serrations in the front, rear, and top, alongside a weight-optimizing window cut. The window cut reduces reciprocating slide mass and minimizes sight movement during recoil. Elite models feature the optic cut standard.

BARRELS

Shadow Systems match-grade barrels are precision machined to improve accuracy and conventionally rifled 1-10 inches. The lug geometry and barrel hood fit is slightly tighter than a conventional barrel, but not enough to compromise reliability. The spiral fluting pattern improves the evacuation of dirt and debris and reduces barrel weight.

SMALL PARTS

Shadow Systems pistols use a modified single spring recoil system which allows the user to adjust and tune the gun with different spring weights. The included recoil spring is a conventional weight flat wire spring manufactured from high-quality chrome silicon material.

All internal slide parts are machined from billet stainless steel. The extractor is our own high-reliability enhanced LCI extractor. The LCI features a serration that increases the sensation of the LCI protruding from the slide when checking by feel in darkness. The extractor features Shadow Systems proprietary geometry and material selection to enhance longevity and extraction of a wide range of ammunition.

Shadow Systems pistols include two magpul 15 round magazines. We are partial to these magazines for several reasons. Aside from their performance in multi-thousand round testing, we appreciate the oversized, serrated basepad which aids in emergency magazine removal particularly with the add-on magazine well installed. These magazines are also substantially easier to disassemble and clean when compared to other designs on the market compatible with our pistol. We view magazine maintenance as a critical aspect of maintaining system reliability. Shadow Systems pistol owners will also benefit from broad magazine interchangeability with Glock-compatible systems.
