GBick1969, guest, from NC, United States, asked on May 08, 2024

Will this hold up on a shotgun?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 08, 2024

Yes, the Holosun OPMOD HS507C-X2 Reflex Red Dot Sight will function as intended paired with a shotgun. All Holosun sights are bench tested to 1000G recoil during design and a statistical sampling is tested during production. Holosun optics are able to take the recoil for larger caliber firearms including .308 and 12GA shotguns.

The fit depends on the optic cutout on the slide. This is made specifically for a RMR slide cutout.

Will solar light recharge optic

A
Answered by JM12, guest, from CT, United States, on March 04, 2026

No it adjusts the brightness automatically. That being said I don’t use that function as it take into account where you are not where the target is and your red dot is on. I thought it recharged it when I bought it but was wrong. Outside of all this I love this optic.

Will this fit a gen 5 Glock 17

A
Answered by Sheridan Lowery, member, from OK, United States, on October 19, 2025

If you have a Glock 17 MOS gun, you need an adaptor plate for MOS to RMR footprint. If you have a gun that is cut for direct mounting of the RMR footprint, you’re good to go.

Will this fit a Sig P322?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on August 14, 2024

The Holosun OPMOD HS507C-X2 Reflex Red Dot Sight will not fit the P322. This optic uses the Trijicon RMR footprint, while the P322 only accepts optics with the RMSc or K footprint. Direct fit options for your P322 include the Holosun 407K/507K, Holosun EPS Carry, Sig Romeo Zero, Shield RMSc, Vortex Defender CCW and more.

Will this work for a Sig M18

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on July 18, 2024

The Holosun OPMOD HS507C-X2 Reflex Red Dot Sight uses the Trijicon RMR footprint and would not be directly compatible with the P320 M18 which uses a Deltapoint Pro optic cut. To mount this optic, you would need to use an Deltapoint Pro to RMR adapter plate such as the C&H Precision Weapons adapter, which can be found linked below. If you do not want to use an adapter to mount an optic, I would recommend using a direct fit option such as the Eotech EFLX, Sig Romeo 1 Pro, Leupold Deltapoint Pro, Holosun SCS-320 and more.

Q
Alonso Quiceno Ortiz, member, from NJ, United States, asked on May 13, 2024

l have a Glock 43X, can you please talk me, this optic fitting?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 13, 2024

The Holosun OPMOD HS507C-X2 Reflex Red Dot Sight is not compatible with a Glock 43X. Optic ready (MOS) models of the Glock 43X are designed to accept optics with the RMSc footprint. The Holosun 507C uses the Trijicon RMR footprint and would not be compatible. If you do not have an MOS model Glock 43X, you can use the Evolution Gun Works Trijicon RMR Sight Mount which will replace your rear sight with an optic plate. The plate itself is wider than your slide but will still function as intended. The adapter plate can be found linked below. If you have any further questions, please email us at Techsales@opticsplanet.com for assistance.

randy, guest, from NM, United States, asked on May 06, 2024

WILL MY SIG P320 X5 ACCEPT THIS OPTIC

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 06, 2024

The P320 X5 Legion is optic cut for optics that use the Deltapoint Pro footprint. The Holosun 507C uses the Trijicon RMR footprint and would not be compatible. If you have the P320 X5 DH3, you will be able to use this optic because that model comes dual-cut for optics with the Deltapoint Pro and Trijicon RMR.
