Primary Arms GLx RS15 Mini Reflex Sight 26X20MM 3 MOA Center Dot with 250 MOA Outer Circle ACSS Vulcan Reticle Direct Mount to SIG P320 Includes Adapter Plate for GLOCK MOS Anodized Finish Black

The Primary Arms GLx RS15 Mini Reflex Sight 26X20MM 3 MOA Center Dot with 250 MOA Outer Circle ACSS Vulcan Reticle is purpose-built for duty-grade handgun applications where rapid target acquisition and low-profile mounting are mission-critical. Designed for direct attachment to SIG P320 platforms with included adapter plate compatibility for GLOCK MOS slide cuts, this mini reflex sight addresses a persistent operational need: reliable, fast-transitioning optics for defensive and tactical pistol work. Law enforcement and military personnel demand sights that maintain zero under recoil, function across temperature extremes, and integrate seamlessly with existing duty holster ecosystems—requirements that drive the GLx RS15's engineering.

The 26X20MM optical window and 3 MOA center dot deliver excellent speed for close-to-medium range engagements typical of defensive pistol scenarios, while the 250 MOA outer circle provides peripheral reference for rapid target location without cluttering the sight picture. The ACSS Vulcan reticle combines proven mil-dot geometry with Primary Arms' legacy of ballistic optimization, enabling users to engage targets at distance if needed without sacrificing the crisp, unobstructed dot required for self-defense work. Hard-anodized black finish resists corrosion and glare, and the compact profile—at 3.25 inches width—clears most holster designs and doesn't impede slide manipulation or charging operations. This robust construction ensures the optic performs as a force multiplier, not a liability.

Users transitioning from iron sights to reflex optics will appreciate the minimal learning curve and intuitive reticle design; agencies standardizing on P320 platforms benefit from the direct-mount interface that eliminates adapter bulk and potential zero shift. The included SIG P320 direct mount and GLOCK MOS adapter plate maximize platform flexibility, allowing shooters to maintain consistency across multiple duty weapons. Installation requires no gunsmithing, and the sight's compact footprint preserves holster compatibility for operators running level-2 or level-3 security devices. Whether deployed in duty, competition, or civilian defensive carry, the Primary Arms GLx RS15 combines proven optical technology with practical ergonomics demanded by professionals.
