The Holosun HS507K-X2 is a compact reflex sight built for concealed carry pistols and defensive handguns. This open-frame red dot sits on the front of your slide—keeping your sight picture fast and your carry footprint as minimal as possible. If you're running a compact or subcompact pistol and want a modern aiming solution that doesn't add bulk, the HS507K-X2 delivers the speed of a red dot without the compromise.

Holosun's HS507K-X2 builds on the proven platform with two practical upgrades. Lock Mode locks the buttons to stop accidental brightness or reticle changes while the sight rides in your holster or travels in your bag. The buttons themselves are repositioned lower and out of the way—a small detail that makes a real difference when you're carrying regularly. The 2 MOA dot is sharp enough for precision on the range yet fast enough for close-quarters work, and unlimited eye relief means you can shoot it however feels natural to you.

Battery life rates at up to 50,000 hours on setting 6, so you're looking at years between changes. Shake Awake brings the sight to life when it detects motion, which means less hassle than hunting for a power button in a defensive moment. Combine that with Holosun's multi-reticle system and the Super LED, and you've got a sight that adapts to how you actually shoot—not the other way around. The matte black finish blends naturally with modern carry guns and stays quiet in the sun.
