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.

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.

Holosun 507k Compact Red Dot by JAMES VAIL JR, Verified Owner, September 6, 2025
First of all Opticsplanet is fabulous to do business with. I'm an old school 1911 shooter and am somewhat new to the use of Red Dot Sights. I ordered a 507C to put on a S&W CSX-E Micro Compact Pistol when a 507K Compact Sight was the better fit. Opti...

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 ...

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...

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...

Product Info for Holosun HS507K X2 Compact Pistol 2x 0.58 x 0.77 in Reflex Red Dot Sight

The HS507K X2 is an open reflex optical sight designed for subcompact pistol applications. The Holosun HS507K X2 improves on the previous version by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.image

Additional features of these Red Dot Sights include Holosun’s Red Super LED with up to 50k hour battery life, Multi-Reticle System, and Shake Awake. The durable housing is made from 7075 Aluminum, uses Holosun’s K footprint, and houses the 1632 battery in a side-mounted tray for easy replacement when needed. The HS507K X2 is a direct for P365X/XL, and requires an adapter plate for slides with a four-boss interface.
