Key Features
- Optic-Ready Slide – The slide is pre-cut for popular red dot footprints (RMR, Holosun, etc.). You don’t need to send it off for milling; mount your optic and zero it in minutes.
- 4.5″ Barrel – Gives you a longer sight radius and better velocity than a standard compact barrel, which translates to tighter groups at distance.
- Aggressive Grip Texture – The polymer frame features deep, sharp texturing that locks the gun in your hand, even with wet or gloved hands. No slipping under recoil.
- Two Magazines Included – Comes with two 15-round magazines (standard capacity). That’s a spare right out of the box, so you can run a loadout or hit the range immediately.
- Glock 19 Holster Fit – Drops into most holsters designed for the Glock 19. That means you can use your existing gear without buying new holsters or mag pouches.
Who It’s For
This pistol is built for the shooter who carries every day and trains regularly. Whether you’re a law enforcement officer, a security professional, or a civilian who takes self-defense seriously, the MR920 LE gives you a combat-ready platform without the custom wait times. It’s also ideal for new shooters moving up from a subcompact to a full-size grip—the ergonomics are forgiving, and the optic cut lets you learn with a red dot from day one.
Pros & Cons
- Pro: Out-of-the-box optic cut saves you $100+ and weeks of waiting on gunsmithing.
- Pro: Fits Glock 19 holsters, so you can use your existing carry gear.
- Pro: Aggressive grip texture gives a secure hold under stress.
- Con: The grip texture can be too aggressive for concealed carry against bare skin—you’ll want a cover garment or an undershirt.

Frequently Asked Questions
Does the MR920 LE come with suppressor-height sights?
No, it comes with standard-height fixed steel sights. The rear sight is dovetailed and can be swapped for suppressor-height sights if you plan to co-witness with a red dot.

Yes. The MR920 LE accepts standard Glock 19 magazines (Gen1-5). It ships with two 15-round magazines, but any Glock 19 mag will function.
What optics fit the slide cut?
The slide is cut for the RMR footprint, which includes Trijicon RMR, Holosun 407C/507C, and similar. You may need a mounting plate for other footprints (check Shadow Systems’ website for compatibility).
