Shadow Systems MR920L Elite Slide Optic Unthreaded Black Barrel, 9mm, 4.5″ BBL, 15rd

The MR920L Elite is long slide version of the MR920 Elite. With the MR920L, you get the concealability of a compact frame with the long sight radius of a full size slide. The MR920L was conceived as the true answer to the question of “How do I get more capability out of my pistol and still conceal it daily?” More Capability: The MR920L and its shorter barrel length cousin, the MR920 Elite, both offer an incredibly high degree of mechanical accuracy. The MR920L however makes it easier to use that mechanical accuracy with an increase in sight radius of ½”. That may not seem like a lot, but it is more than enough to notice by an experienced shooter. The MR920L also features significantly less upward snap than the MR920 Elite. There was noticeably less felt recoil under test conditions using the same ammunition and the same shooter, fired consecutively. Both of those benefits can be had in a pistol that is just as easily hidden as the MR920 Elite.

The MR920L is built on the MR920 compact frame, designed for optimal recoil control and improved ergonomic fit. The frame features interchangeable backstraps to fit your natural point of aim, a recoil control ledge, and a tapered, elongated beavertail. The MR920 frame is textured in a way that is aggressive without being uncomfortable for daily carry. The optional magwell can be added to the frame for faster reloads, making the MR920L an excellent choice for competition pistols; the MR920L is approved for use in USPSA Production, USPSA Carry Optics, IDPA Stock Service Pistol, and IDPA Carry Optic divisions.

The full length slide features directional serrations in the front, rear, and topside of the slide alongside recoil-reducing, weight-optimized window cut. The patent-pending optic cut on the MR920L allows a low, direct mount for multiple footprints to accommodate most major optic brands. The optic cut features:

The strongest, deepest screw placement in the industry
Direct optic mounting of multiple brands without intervening adapter plates
Extremely low optic placement permitting most optics to co-witness with typical iron sights
No past optic cut designs have combined all three of these game-changing attributes. The MR920 optic cut accommodates Trijicon RMR and SRO, Holosun 507c and 508t, Leupold Deltapoint Pro, Vortex Viper, and TruGlo Tru-Tec. Because the MR920 is a Universal Optic Mount Pistol, it will likely accommodate additional brands and optics; testing for optic compatibility is still ongoing. The new system provides versatility without compromise and even exceeds the strength of past Shadow Systems mounts that had a dedicated Trijicon RMR footprint machined into the slide.

The slide and barrel are machined right here in Plano, Texas. Barrels are 1-10″ conventionally rifled 416R stainless steel. Our barrels are coated in super hard Bronze Titanium Carbo-nitride or Black Nitride. Slides are machined from 17-4 PH stainless steel and coated in Nitride. The MR920L can be configured with a 4.5″ unthreaded barrel or a 5″ threaded barrel.

The MR920L unthreaded features a 4.5” barrel and corresponding length slide. A MR920L with a threaded barrel features an additional ½” of barrel but the same slide length. So when looking for holsters look for ones compatible with G17-length guns and don’t forget to check for compatibility with your threaded barrel.

Our triggers are improved over a stock trigger, but leave internal safeties fully intact and use stock weight springs. You can expect smooth take-up and a super crisp break at 4.0-4.5 lbs.
