The Shield Sights Low Profile Slide Mount for Glock 17/19 is a precision mounting solution designed to install red dot sights directly onto your pistol's slide, replacing the factory rear sight. This low-profile mount works with Shield's popular RMS, RMSw, SMS, and SMS2 optics, as well as the Jpoint system, giving you a clean, co-witnessed setup that doesn't require gunsmithing. Whether you're building a duty gun, a competition rig, or upgrading a carry pistol, this mount integrates your optic seamlessly while maintaining the Glock's slim profile.

Shield Sights engineered this mount specifically around Glock's slide architecture, so installation is straightforward on the 17 and 19—the two most popular models in the lineup. The compact design accommodates RMS, SMS, and Jpoint optics, which sit narrower than the mounting plate itself, creating a solid, shake-proof connection. If you're running RMSc or SMSc footprint optics, those will also fit, expanding your optic options down the road.

Low-profile mounts like this one keep your sight line as close to the slide as possible, which matters for ergonomics, holster fit, and overall gun handling. The mount replaces your rear sight completely, so you'll lose the iron backup—but if you're mounting a quality red dot with a proven track record, most shooters find that trade-off worth it. This is the no-fuss way to get a modern optic on a Glock without permanent modifications.

Frequently Asked Questions

Will this mount fit my Glock model?

This mount is designed specifically for the Glock 17 and Glock 19. It replaces the rear sight and mounts directly to the slide, so compatibility is limited to these two platforms.

What red dot optics work with this Shield Sights mount?

The mount is optimized for Shield's RMS, RMSw, SMS, SMS2, and Jpoint optics. The RMSc and SMSc will also fit, though they're narrower and sit within the mounting plate footprint.

Do I lose my iron sights with this mount?

Yes—this mount replaces your factory rear sight. Once installed, you're running the red dot as your primary aiming system. Some shooters add a front sight post or co-witnessed irons separately, but the mount itself is sight-replacement only.

Is gunsmithing required to install this mount?

No gunsmithing is needed. This is a direct replacement for the rear sight, designed to fit Glock's dovetail cut without modification to the slide.
