Holosun has built a reputation for listening to shooters who actually burn ammo and run stages, not just those who admire optics from behind a counter.
The new 507-PROMAX feels like it came straight out of that feedback loop.
It’s a pistol optic aimed squarely at shooters who care about speed, transitions, and keeping the dot where it belongs when things get hectic.
The first thing you notice is the window. At 0.91 x 0.67 inches, it’s bigger than what many shooters are used to, and that extra glass pays off immediately on the draw and during wide transitions.
Losing the dot during recoil or when snapping between targets is one of the most common frustrations with slide-mounted optics, and the PROMAX does a solid job of minimizing that problem.

The forward-leaning sunshade isn’t just there for looks, either. It helps cut glare and keep the reticle crisp when lighting conditions get weird, whether you’re shooting outdoors, under range lights, or moving between the two.
At the center of the optic is Holosun’s Performance Reticle System (PRS). It gives shooters more flexibility than a simple dot without turning the sight picture into a mess.
You get a 2 MOA center dot, plus selectable 8, 20, or 32 MOA circles, available in red, green, or gold. The smaller circle helps snap the eye to the dot on the draw. While the larger options work as visual guides during fast strings or awkward shooting positions.
If you want a clean dot, you can run it that way. If you want more reference points for speed, they’re there when you need them.

The housing is built from 7075-T6 aluminum, so it’s not a fragile competition-only piece. At 1.55 ounces, it doesn’t feel like it’s dragging the slide down, and it uses the RMR footprint, which keeps mounting simple on most modern pistols. No plates or proprietary cuts required.
Power comes from a CR1632 battery rated for up to 50,000 hours. Backed by Shake Awake and reticle memory so the optic turns on when you need it and stays out of your way when you don’t.
The forward-facing light sensor reads ambient light from the target’s direction. Not behind the gun, which helps keep brightness consistent as conditions change.
Holosun isn’t pretending the 507-PROMAX is magic. It won’t fix bad fundamentals or sloppy stage plans.
But for shooters pushing pace, chasing cleaner runs, or just wanting a more forgiving sight picture under pressure, it checks a lot of boxes. We’ll be getting hands-on time with it soon at SHOT Show 2026 to see how it holds up when the timer starts.
