Shadow Systems - Manufacturers - Top Gun Supply

The Shadow Systems Match Barrel for MR918 has a straight fluted pattern that reduces the weight of the barrel while adding somewhere for dirt and debris to exit when cycling. It is precision machined to drop-in more easily and fits tights in critical lock up areas. This highly improves accuracy!

All of our barrels are 100% Made in the USA and are custom designed from U.S. sourced materials.

416R Stainless Steel, 1/10″ Broach Cut Rifling – Safe with lead bullets.
TiCN (Titanium CarboNitride) Bronze Finish

Compatible Gun Models Include: Shadow Systems MR918 Elite, Shadow Systems MR918 Combat, Glock 19 (Gen3, Gen4, and Gen5 G19)

The MR918 set a new benchmark for low recoil and controllability in rapid-fire. The dust cover now includes a recoil control ledge for the support hand thumb. This control point further reduces muzzle flip in rapid-fire. The frame of the MR920 continues to feature the NPOA backstrap system which adjusts the ANGLE of the backstrap to match the shooter’s natural point of aim. The pistol system includes three backstraps, a removable magazine well, and a backstrap removal tool for your convenience.

Our pistols are built for reliability and performance first. We added the universal optic mount feature to the MR920 to make your life easier. 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.

This pistol also has a spiral threaded DLC (Diamond-Like Carbon) barrel.

This pistol also has an unthreaded spiral black barrel and a long slide.

This optic ready stripped slide includes a weight-reducing window cutout & pocket cuts. It features front and rear serrations angled to minimize friction on the draw while also providing an aggressive gripping surface so you can accurately manipulate the weapon at high speed.

This custom slide is made to fit the Glock G19 in either Gen3 or Gen4 models and is the perfect way to upgrade your Glock 19 or complete your P80 build. Made in the USA.

Optic cut is compatible with the Trijicon RMR and Holosun 507C. The slides feature heavy duty posts that increase the strength of the system and allow full thread engagement for the mounting screws. We believe this makes our slide one of the strongest, lowest profile designs in the industry. Using the RMR to rack the slide is no problem.

NOTE: your slide will come with a 3/8 in. 4-40 and two 5/16 in. 4-40 screws. For mounting a Trijicon RMR, place the 3/8 screw on the NON-EJECTION PORT SIDE. For mounting a Holosun, use 5/16 in. screws on both sides.

Choose Glock Generation Compatibility for Gen3 or Gen4
Fits all variants of the Trijicon RMR and Holosun 507C
17-4 Stainless Steel Slide
Optic mounting screws included
