Meet the MR918 Combat.  This is Shadow System’s no-nonsense answer to a fighting pistol but includes features normally found only on the finest custom guns.

The MR918 name comes from the idea of creating a true “multi-role” 9mm pistol.  The size and operating system are inspired by the Glock Gen4 G19 model, but many aspects have been completely redesigned.

The frame has been in development for two years and is 100% a Shadow System design, not a rebrand of another frame already in the market.  The frame makes use of new manufacturing techniques to wrap more texture around the curves of the frame and put grip texture in places not normally seen on production guns.

Multi-Role 9mm Frame

  • Compatible with existing Glock Gen4 G19 holsters, magazines, and accessories
  • Designed to dramatically reduce recoil and muzzle flip
  • Contoured frame sits low in the hand
  • Features double undercut trigger guard
  • 3 interchangeable backstraps supporting high, neutral, and low Natural Point of Aim
  • Gently extended beavertail prevents slide bite
  • Aggressive grip texture on key surfaces
  • Included magwell extension enables faster reload under stress

MR918 Slide

  • Designed for recoil control and manipulation under stress
  • Front/rear directional serrations for improved handling
  • Thinned slide profile at grasping locations
  • Machined from 17-4 stainless steel

MR918 Sights

  • Metal sights with solid black rear and a high-visibility green outline tritium front
  • Nearly as bright as a fiber optic in the daytime
  • Glowing tritium dot gives a nighttime index point for quick, accurate shots at close range
