Shadow Systems

The MR918 name comes from the idea of creating a true “multi-role” pistol. The size and operating system of the multiple role pistol is inspired by the Glock Gen4 G19 model, but many aspects have been redesigned. Designed to dramatically decrease recoil and muzzle flip it features a double undercut trigger guard. Comes with a slightly extended beavertail to prevent slide bites and ships with 3 interchangeable backstraps that provide backup for high, neutral and low natural point of aim. The trigger is a polymer flat face design with a 4-4.5 lbs trigger pull. The 4" threaded barrel is machined from 416R stainless steel and is fluted to improve evacuation of debris and reduce weight. Equipped with metal solid black rear and a high visibility outlined green tritium front sight. The slide is Optic Ready cut for Trijicon RMR or Holosun and features a lower 1/3 co-witness. Ships with 2 magazines and a soft pistol case.

The Elite model MR918's have a specifically engineered window cut to reduce weight slightly for optimal recoil impulse and fast sight recovery. The top of the slide also has extra serrations.

This custom slide is made to fit the Glock G19 Gen4 models and is the perfect way to upgrade your Glock 19 or complete your P80 build. The slide is made of 17-4 Stainless Steel with a Diamond-like Carbon (DLC) finish making them scratch and wear resistant. Precision cut front and rear cocking serrations provide the shooter with a positive grip for any slide manipulation. Made in the USA!

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.

Optics Ready Slide Includes:

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
Slide is completely stripped and does not include Channel Liner

Shadow Systems realized it was time for an improvement over the stock Glock extractor, without the relatively high price of a billet. MIM technology has improved dramatically in recent years, in particular, the possibility of using new materials. Since so many customers loved their machined billet 17-4 stainless steel extractor, they decided their MIM extractor should use this same material.

What you get with the Enhanced LCI High-Reliability Extractor is:

• Improved materials and part density over stock MIM extractor
• Improved claw geometry for consistent 3 o’clock ejection and no brass to the face
• Higher dimensional consistency
• Enhanced LCI area for a greater tactile response when choosing enhanced LCI variants
