Questions & Answers
Will this fit on the M&P 5.7 ? Expert Answer

The Holosun HS507K Compact Pistol Red Dot Sight will mount directly to the optic ready slide of the M&P 5.7 without the need for an adapter plate.

by Ethan, Gear Expert, March 6, 2023
Is it suitable for a Glock 40 MOS 10mm Auto? Thanks Expert Answer

To mount the Holosun HS507K Compact Pistol Red Dot Sight to your Glock 40 MOS, you will need to use the C&H Precision Weapons V4 MIL/LEO Adapter Plate (linked below). Keep in mind that this optic was designed for micro pistols, while your Glock 40 can accept optics with full sized footprints such as the RMR, Deltapoint Pro, Docter, and C-More footprints.

Helpful Positive Review Nice sight but not RMS-C footprint by Bonbonjon, Verified Owner, August 2, 2023
NOT RMS-C FOOTPRINT. After receiving it and finding it to not fit, a quick web search shows Holosun is calling this a "modified RMS-C" footprint. Bought for my 43x MOS. Assume it will not fit any Glock MOS without adapter plate or modification. I ...

Helpful Positive Review What can I say, it's a Holosun, after all! by edquichan, November 25, 2023
It's a great carry option. Due to the RMS shield footprint, the installation on my P365X was a breeze. It comes zeroed at 25 yds. from the factory, however, I did adjust mine. The ACSS reticle assist in rapid site acquisition.   Good brightness s...

Helpful Positive Review Highly recommend by Cree, Verified Owner, January 11, 2024
First off, i have an astigmatism and I prefer RED optics vs green. Ive owned both and red always looks better to me. If you're on the fence about it then just get it. You won't be disappointed. I've owned several holosun optics with different reticle...

Helpful Positive Review Best red dot for handguns by GHaines, March 30, 2024
The ACSS Vulcan reticle is a superior option for anyone needing a little help finding the red dot quickly upon presentation with handgun. I have this Holosun for both my Glock 19 and 43x MOS.

Product Info for Holosun HS507K Compact Pistol 2x 0.58 x 0.77 in Reflex Red Dot Sight

Made as a collaboration between Holosun Optics and Primary Arms Optics, the illuminated HE507K with ACSS Vulcan Dot Reticle brings the revolutionary Vulcan aiming system to a micro reflex footprint.image

Designed for concealed carry, the HE507K is lightweight, durable, and dependable, with up to a 40,000-hour runtime on medium settings. This sight retains all the core features and technologies of the standard Holosun model, including the Multi-Reticle System, Shake Awake technology, and a built-in Lock Mode. With 12 illuminated brightness settings and intuitive push-button controls, the HE507K works in any lighting condition and is even compatible with night vision devices.

This co-branded optic features the ACSS Vulcan Dot reticle system, which improves acquisition and recovery speed through its patented outer reference circle. When aimed on-target, the ACSS Vulcan Dot reticle appears as a simple, unobtrusive 3 MOA dot. When your aim is off-target, the edge of the 230 MOA outer circle guides you back to center. ACSS Vulcan Dot alleviates one of the main weaknesses of micro reflex optics, ensuring you can always find your reticle aiming point, despite the smaller optical aperture.

The HE507K with ACSS Vulcan Dot Reticle features an RMSc footprint and is natively compatible with many of the most popular concealed carry pistols.
