Holosun’s New 507-PROMAX

Holosun has always approached pistol optics from a shooter’s point of view: start with the problems that show up on the clock and build hardware that quietly takes them off the table. The new 507-PROMAX is a direct expression of that mindset. It is built for high-tempo shooting where split times shrink, transitions get wider, and sight tracking becomes the deciding factor. With an enlarged window, a forward-leaning sunshade, and a purpose-built Performance Reticle System, the 507-PROMAX provides competitive and performance-driven shooters with more usable information in every presentation, without adding clutter or gimmicks.
Where most pistol optics require shooters to adapt their stage plan to a fixed reticle, the 507-PROMAX allows the reticle to adjust to the shooter. At the heart of the system is Holosun’s Performance Reticle System (PRS): a precise 2 MOA center dot anchored by selectable 8, 20, and 32 MOA circles in Red, Green, or Gold. That geometry isn’t decorative; each ring becomes a visual reference that serves a specific role. A 2 MOA circle helps the eye catch sight faster on the draw and stay locked through recoil. Intermediate 8- and 20-MOA circles give the shooter indexing tools for partials, awkward positions, or fast transitions across steel arrays. On demand, the optic can be set up as a clean dot, a coarse circle, or a layered reticle that matches the stage and the shooter’s style.
The housing and window work quietly in the background to support that reticle. Built from 7075-T6 aluminum, the 507-PROMAX maintains the durability shooters expect while carving out a noticeably broader sight picture than the previous 507COMP. The 0.91 × 0.67-inch window is framed by a forward-leaning sunshade that helps cut glare and preserve contrast on the reticle in inconsistent lighting, whether that’s bright outdoor bays, artificial indoor light, or mixed environments where the shooter moves from dark to light in a single run. Weighing in at just 1.55 ounces, the optic maintains a balanced feel on the slide. It sits on the familiar RMR footprint, maintaining compatibility with pistols already cut to that pattern.
Power and controls are built for people who’d rather spend their time shooting than babysitting an optic. Read more
