Product Overview

The Radian Guardian is a machined aluminium optic guard for Glock MOS pistols, mounting to the MOS optic cut around a Trijicon RMR, Holosun EPS or Holosun 507C Comp footprint red dot.

A machined aluminium shroud that wraps and protects your pistol red dot — turning a fragile optic into a duty-ready one.

The Radian Guardian is a hardcoat-anodised aluminium optic guard for Glock MOS pistols. It surrounds the red-dot sight on three sides, taking impacts, drops and holster wear that would otherwise crack an exposed emitter or knock zero. It also serves as a rugged rear cocking surface — rack the slide one-handed off a belt or barricade. Machined to the specific optic footprint so the fit is exact and the sight window stays clear.

Why shooters choose the Guardian

  • Protects the optic on three sides — impact, drop and holster wear
  • Rugged rack surface — one-handed slide manipulations
  • Footprint-specific fit — exact, with a clear sight window
  • Hardcoat-anodised aluminium — duty-grade durability

What the Guardian fits

Fits Glock MOS-cut slides and mounts using the MOS optic screws. Each version is machined for a specific optic footprint — Trijicon RMR, Holosun EPS or Holosun 507C Comp — so select the one matching your sight and confirm your optic's footprint before ordering. It is not a universal shroud, and a mismatched footprint will not mount. With backup iron sights built into the same shroud it becomes the Guardian+Six.

Product Questions

Will the Guardian fit my pistol and my optic?
It fits Glock MOS-cut slides and mounts using the MOS optic screws, so the pistol side is straightforward. The optic side is not universal — each version is machined for one footprint, and this listing covers the Trijicon RMR, Holosun EPS and Holosun 507C Comp. Confirm which footprint your red dot uses before ordering, because a mismatched version will not mount.
What does the Guardian actually protect against?
It wraps the red dot on three sides, so impacts, drops and holster wear land on machined aluminium rather than on the sight housing or the glass. That is what turns an exposed pistol optic into something that keeps its zero through hard use. The rear face doubles as a rugged racking surface, so you can cycle the slide one-handed off a belt, a heel or a barricade.
How does it compare with the Guardian+Six?
The Guardian+Six is the same idea with backup iron sights built into the shroud, so you keep a usable sight picture if the dot ever fails. This version is the guard alone, which keeps the unit simpler and the sight window clear if you already have irons on the slide or do not want them. The two listings cover different optic footprints, so check yours against the one you are buying — both sit under Radian Weapons.
Is fitting straightforward?
It mounts on the Glock MOS optic screws with the hardware supplied, which means the optic has to come off and go back on as part of the job. Because you are removing the sight, re-check and confirm your zero afterwards rather than assuming it has held. Torque the optic screws to the figure your optic maker specifies.
How will it arrive?
Optic guards are sent from the United Kingdom with free tracked UK delivery in 7–10 days, and you’ll get tracking by email when it ships. If a part turns out to be the wrong fit, see our returns policy or contact us and we’ll help sort it.
