Questions & Answers
What footprint is this? Expert Answer

The Holosun 507 Comp (Competition) utilizes the Trijicon RMR optic footprint and will be compatible with any RMR cut slide or RMR mount.

Will this fix my Glock model 45? Will it require a gunsmith or does it attach to the rear site mount? Expert Answer

If you have the Glock 45 MOS (optic ready), you will use the #2 adapter plate included with your Glock to mount this optic. If you do not have an MOS model Glock 45, you must use a dovetail adapter plate or have your slide milled for an RMR pattern optic. The adapter plate that will allow you to install this optic can be found by using the link below:

Masterpiece on a 2k11 by Jon, Verified Owner, June 1, 2026
Mounted this 507comp on my new 2k11 Pro Comp. Wide window and follow up shots is fast due to target window. My buddy who has an SRO is now eying one to replace what’s mounted on his Atlas

Holosun 507 Comp by ER, Verified Owner, July 31, 2026
I’ve tried over a dozen different red dot optics and came back to the 507 Comp. My favorite dot/circle displays are the 2moa dot with the 8 moa circle or 20 moa circle. Love that it doesn’t has the clutter of the dash lines most other brands put at t...

Best Value by Butch, Verified Owner, August 7, 2026
Great optic, dot or circle or dot/circle's. No annoying dash lines at the 12-3-6-9 o’clock position that clutter up the sight window with no purpose.

great sight! by Elmers44, Verified Owner, January 7, 2026
New to red dots. Chose this one because of reviews, warranty, and mostly due to largest window and most options on reticule and brightness. Extremely pleased at every level.

Perfect for my Shotgun! by Kevin Bisson, Verified Owner, May 12, 2025
I know many mount these on their "competition" pistols, however, I chose to mount this on my Mossberg 590A1 SBS. I love the large window size. It has held up to buckshot and slugs, and the accuracy with the green dot has been awesome. If it can handl...

Product Info for Holosun HS507COMP 1x1.1x0.87in Reflex Red Dot Sight

507Comp-RD/507Comp-GR handgun sight features a large 1.1” x 0.87” objective lens for enhanced shooting performance and Holosun’s new Competition Reticle System (CRS) with Holosun’s 650nm Red/540nm Green Super LED and up to 50k hour battery life with a 1632 cell.image

CRS is an enhanced multi-reticle system with four components including a precision 2MOA dot, an 8MOA circle, 20MOA circle, and 32MOA circle with multiple combination settings to suit individual shooter preference.  507Comp-RD/507Comp-GR is made from 7075 aluminum with an industry standard footprint, and includes Shake Awake technology

Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optic’s LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed.
