Frequently Asked Questions

What are the key differences between the Shadow Systems MR920 Elite and Combat models?

The MR920 Elite features window cuts on the slide for faster cooling and to offset optic weight. The Combat configuration omits these cuts, prioritizing protection against debris in defensive situations.

What makes the Shadow Systems MR920's optics cut unique?

The MR920 features a nearly universal optics cut that doesn't require mounting plates. It uses a re-engineered internal retaining bar to accommodate longer screws and multiple screw patterns for brands like Trijicon, Holosun, Vortex, and Leupold.

Is the Shadow Systems MR920 compatible with standard Glock holsters?

Yes, the MR920's trigger guard geometry was modified to ensure universal fit in standard Glock holsters, specifically G17, G19, and G34 models. Testing confirmed compatibility with Safariland ALS and various Kydex holsters.
