Holosun 507 PROMAX PRS

• Performance Reticle System: The PRS setup gives this sight a precise 2 MOA dot plus selectable 8 MOA, 20 MOA, and 32 MOA circle options, so it can be tuned for careful shot placement or faster visual pickup in dynamic pistol shooting.
• Expanded competition window: The 22x28 mm window provides a larger sight picture that helps the shooter reacquire the dot sooner during recoil and move between targets with less searching.
• Forward-leaning sunshade: The integrated hood reduces glare and reticle washout in bright light, helping the aiming point stay easier to read on outdoor ranges and in harsh daylight.
• Solar Failsafe and Shake Awake: Solar backup and motion activation keep the optic ready while reducing unnecessary battery drain, which supports dependable use over long training and match schedules.
• RMR footprint compatibility: The Trijicon RMR standard footprint makes the sight easier to fit on many optics-ready pistol slides and mounting plates already built around this common interface.

About the Holosun Reflex Series

Holosun Reflex covers the company’s open reflex sight family, including compact pistol optics and larger open sights for long guns. Within that lineup, the 507 series is the pistol-focused branch, developed around a micro open-emitter format that keeps weight low while preserving a clear, fast sight picture. The series is aimed at shooters who want a practical red dot or green dot sight for handgun use, whether for range work, competition, defensive setups, or general shooting.

A defining trait of this family is its emphasis on adaptable reticle systems and user-friendly electronics. In the 507 line, Holosun pairs compact dimensions with features such as selectable reticle options, Shake Awake, and Solar Failsafe, giving the sights a broader operating envelope than a basic fixed-dot design. The overall design philosophy is straightforward: keep the optic small enough for slide mounting, but add the features that help shooters pick up the reticle faster, manage battery life more efficiently, and tailor the sight picture to different shooting styles. That makes the Reflex series, and especially the 507 family, a strong fit for modern pistol optics use.

About the Holosun 507 PROMAX PRS

The Holosun 507 PROMAX PRS is a 1x open pistol sight built around speed, visibility, and reticle flexibility. Its most obvious advantage is the enlarged viewing window, which gives the shooter more visual space around the aiming point. In practice, that helps with dot acquisition on the draw, faster tracking during recoil, and smoother transitions between multiple targets. The forward-leaning sunshade adds a practical benefit in bright conditions by reducing glare that can otherwise make an open-emitter sight harder to read.

This model uses Holosun’s Performance Reticle System with a green reticle, combining a fine 2 MOA dot with selectable 8 MOA, 20 MOA, and 32 MOA circle options. That gives the sight a wider operating range than a simple single-dot optic. The small dot supports more precise aiming, while the larger circle options are easier to catch quickly when speed matters most. Manual brightness control, daytime-visible illumination, and 8 daylight plus 4 night-vision settings help the reticle stay usable across very different lighting conditions.

Mechanically, the sight is designed for hard use on a pistol slide. The 7075-T6 aluminum housing keeps the body strong without adding unnecessary bulk, while the side-loading CR1632 battery allows battery changes without removing the optic from the firearm. With 1 MOA click adjustment, ±30 MOA windage and elevation travel, an RMR footprint, and Holosun features such as Solar Failsafe and Shake Awake, the 507 PROMAX PRS is configured for shooters who want a competition-oriented handgun red dot sight that remains practical for regular training and demanding field use.
