Holosun HS507-PROMAX-RD-PRS Pistol Red Dot Sight

New for 2026, the 507-PROMAX-RD is Holosun’s biggest-window open pistol sight in the 507 line. A 1.18″ x 0.98″ window gives you a wider view for faster target transitions and easier dot tracking under recoil. A forward-leaning sunshade cuts glare so the reticle stays crisp in bright light. It runs Holosun’s 650nm Red Super LED on a CR1632 battery rated up to 50,000 hours.

The Performance Reticle System (PRS) gives you a precision 2 MOA dot with selectable 8, 20 and 32 MOA circles, so you can set it up for speed, precision or both. The housing is hard-anodized 7075-T6 aluminum on the industry-standard RMR footprint, so it mounts directly to a wide range of optics-ready slides.

Shake Awake™

Shake Awake extends battery life by shutting off the LED when the optic isn’t moving. A motion sensor keeps the dot on while you’re using it, and once the firearm is stored and still, the optic powers down after a set period. The slightest movement brings the dot back on instantly, so it’s ready when you pick it up.

Solar Failsafe

A built-in solar panel provides backup power and supports brightness in changing light, so the optic keeps working even as the battery runs down.

Side-Loading Battery

The CR1632 battery loads from a side tray, so you can swap it without pulling the optic off the slide and losing zero.

Lockout Mode

Manual brightness controls include memory and a lockout function, so your settings don’t get bumped mid-stage.
