Holosun 507-PROMAX Performance Pistol Optic

Maximum Window. Maximum Speed.

The Holosun 507-PROMAX is a performance-focused open-emitter pistol optic designed for shooters who prioritize a large viewing window, rapid reticle acquisition, and fast target transitions.

Building on the popular 507COMP platform, the 507-PROMAX features an even larger 1.18" × 0.98" viewing window paired with a distinctive forward-leaning sunshade designed to reduce glare and maintain reticle visibility in bright shooting conditions.

At the center of the 507-PROMAX is Holosun's upgraded Performance Reticle System (PRS). The selectable system combines a precise 2 MOA dot with 8 MOA, 20 MOA, and 32 MOA circle options, allowing the shooter to configure the sight picture around speed, precision, or personal preference.

The 507-PROMAX is available with your choice of a Red, Green, or Gold reticle and uses the popular RMR footprint for broad mounting compatibility.

Available Configurations

Red

The 507-PROMAX Red features Holosun's red Performance Reticle System for a crisp, familiar sight picture.

The selectable PRS allows the shooter to configure the optic around the 2 MOA dot and 8, 20, or 32 MOA circles, making it easy to tailor the reticle for competition, defensive use, or general range shooting.

Holosun Model: HS507-PROMAX-RD-PRS

Green

The 507-PROMAX Green combines the large competition-oriented window with Holosun's high-visibility green Performance Reticle System.

For shooters who prefer green over a traditional red aiming point, this version provides the same selectable PRS and performance-focused housing.

Holosun Model: HE507-PROMAX-GR-PRS

Gold

The 507-PROMAX Gold offers Holosun's distinctive gold Performance Reticle System as an alternative to traditional red and green reticles.

The gold reticle maintains the same selectable 2 MOA dot and multiple circle configurations while providing a different visual presentation for shooters who prefer the contrast of a gold aiming point.

Performance Reticle System

The Performance Reticle System (PRS) is one of the defining features of the 507-PROMAX.

Rather than limiting the shooter to a single dot or circle-dot configuration, the PRS provides multiple selectable aiming references:

• 2 MOA Dot

• 8 MOA Circle

• 20 MOA Circle

• 32 MOA Circle

These elements can be used individually or in selectable combinations, allowing the optic to be configured around the shooter's preference.

Run the 2 MOA dot for a clean and precise sight picture, select one of the larger circles for rapid visual acquisition, or combine the dot and circle for a more prominent aiming reference.

For competition shooters in particular, the ability to change reticle configuration provides considerable flexibility between different stages and shooting styles.

Enlarged Competition Window

The 507-PROMAX features a massive 1.18" × 0.98" viewing window, providing an even larger sight picture than the previous 507COMP.

The expanded window gives the shooter more usable glass for finding and tracking the reticle during:

• Rapid presentations

• Recoil

• Target transitions

• Unconventional shooting positions

• Movement

• Competition stages

For shooters who prioritize speed, the larger window makes it easier to maintain visual contact with the reticle without requiring a perfectly centered presentation every time.

Forward-Leaning Sunshade

One of the most recognizable changes to the 507-PROMAX is its integrated forward-leaning sunshade.

The extended front portion of the housing helps reduce glare and reticle washout in harsh or direct lighting conditions.

This is particularly useful for outdoor competition and range environments where changing sunlight can make maintaining a consistent sight picture more difficult.

Solar Failsafe™

The 507-PROMAX incorporates Holosun's Solar Failsafe™ technology.

The integrated solar system supplements the optic's battery-powered operation and provides an additional layer of redundancy.

Combined with the optic's other power-management features, Solar Failsafe helps keep the 507-PROMAX ready for extended use.

Shake Awake™

Holosun's Shake Awake™ technology helps conserve battery life by allowing the optic to enter a dormant state during periods of inactivity.

When movement is detected, the optic automatically wakes and returns to operation.

This provides the convenience of keeping the optic ready without requiring the shooter to manually power it on each time the pistol is used.

Side-Loading Battery

The 507-PROMAX uses a CR1632 battery housed in a convenient side-loading battery tray.

The battery can be replaced without removing the optic from the pistol, helping preserve mounting position and eliminating unnecessary optic removal and reinstallation.

RMR Footprint

The Holosun 507-PROMAX uses the widely supported RMR mounting footprint.

This provides compatibility with a large selection of:

• Factory optics-ready pistols

• Direct-milled slides

• Optic plates

• Aftermarket mounting systems

• Custom OSA optic-cut slides

Always verify the specific firearm, slide, and mounting system for compatibility before installation.
