Shield Sights SMS/RMS Mount for Glock 17&19

• Low-profile mounting position: This rear-sight replacement mount keeps a Shield RMS or SMS optic as close to the slide as possible, helping preserve a natural presentation and making the transition from iron sights to a red dot more intuitive.
• No slide machining required: The mount lets a Glock 17 or 19 accept a Shield-footprint sight without cutting the slide or starting with an MOS-ready pistol, which is a practical option for upgrading a standard handgun.
• Shield RMS/SMS interface: Built around the Shield RMS/SMS mounting standard, it gives a direct fit for compatible Shield mini red dot sights and keeps the installation focused on the optic footprint these sights were designed around.
• Secure wedge-based installation: The design uses a custom brass fixing wedge to lock the polymer plate into the rear sight dovetail, creating a stable mounting solution while avoiding permanent modification to the pistol.
• Compact, purpose-built construction: With a matte black finish and aluminium structure, this mount is made to blend cleanly with the pistol and optic while standing up to regular carry and range use.

About the Shield SMS/RMS Series

The Shield SMS/RMS series covers a broad family of mounting solutions built around Shield’s compact red dot footprint. Within the range, Shield Sights includes mounts and adapters intended for SMS and RMS optics, giving users multiple ways to fit these sights to pistols, rifles, shotguns, and rail-equipped platforms. That makes the series relevant both to shooters setting up a carry pistol and to those adapting a mini reflex sight for sporting or practical use.

A defining trait of the series is its focus on firearm-specific mounting options. Rather than relying on one universal plate, the line includes slide plates, dedicated adapters, and rail mounts shaped around particular applications. Picatinny and Weaver adapters are part of the family, and scope-tube mounts for 30 mm and 34 mm tubes extend the same footprint into carbine and shotgun setups. Across the series, the design philosophy is straightforward: keep Shield mini sights easy to integrate, keep the mounting interface consistent, and offer solutions that suit different firearms without changing the optic itself.

About the Shield Sights SMS/RMS Mount for Glock 17&19

The Shield Sights SMS/RMS Mount for Glock 17&19 is designed for shooters who want to fit a compact red dot to a standard Glock slide without committing to machining work. By replacing the rear sight and using a dedicated insert system, it provides a practical route to mounting a Shield RMS/SMS footprint optic on a Glock 17 or 19 while keeping the sight line notably low. In use, that lower position helps the pistol feel less top-heavy and can make dot acquisition faster because the optic sits closer to the bore and closer to the presentation angle many shooters already know from iron sights.

This mount is especially useful for carry, defensive training, and general range work where a simple, non-permanent installation matters. The rear-sight replacement format avoids the need for an MOS slide or custom milling, so it suits pistols that were not originally cut for optics. Shield’s design also uses a custom brass fixing wedge to secure the mount in place, which supports a stable fit while keeping the installation reversible. Finished in matte black and built from aluminium, the mount is made to integrate neatly with the pistol and with Shield mini reflex sights such as the RMS, SMS, and JPoint-compatible setups noted for this platform. The result is a compact handgun red dot mount that prioritises low mounting height, straightforward fitting, and compatibility with Shield’s established mini sight standard.

About Shield Sights

Shield International was formed in Great Britain in 1983, and the company has long focused on firearm sighting systems for military, law enforcement, and civilian users. Shield’s work in compact reflex optics goes back decades: its original mini red dot sight design dates to 1996, and related Shield mini sights have also appeared under names including Firepoint, Tasco Optima, Trijicon RedDot, and JPoint. That history is especially relevant in the mini red dot category, where footprint consistency and long-term platform support matter.

Shield also developed the Close Quarter Battlesight for the UK military and later introduced the civilian-oriented Close Quarter Sportsight in 2011. Its product range includes mini red dot sights and rifle sights, with a design approach centred on compact dimensions and practical mounting solutions. For products such as the SMS/RMS Glock mount, that background shows in the emphasis on low-profile installation and compatibility with Shield’s established optic interface.
