Mounting a Holosun HE508T-RD-X2 to a Glock 17 Gen 4 can be done in multiple ways. If you have an MOS (optic ready) model Glock 17, you can use the #2 optic adapter plate included with your Glock. If you do not have an MOS model Glock 17, you can have your slide milled for the RMR footprint by a gunsmith or use a dovetail adapter plate. The correct dovetail adapter plate needed to mount this optic can be found linked below:

Will this fit a p365xl Romeo edition?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 27, 2024

No, the Holosun HE508T-RD-X2 uses the much larger Trijicon RMR footprint. Your P365XL will only fit optics that use the RMSc or K footprint such as the Shield RMSc, Vortex Defender, Holosun EPS Carry, Holosun 407K/507K, Holosun SCS Carry and more.

Will this fit the sig p365 xl

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on January 06, 2023

The Holosun HE508T-RD-X2 Red Dot Sight is not compatible with the Sig P365XL. It uses the larger RMR footprint while the P365XL is cut for optics with the smaller RMSc or K footprint. You can fit optics like the Shield RMSc, Sig Romeo Zero, Holosun EPS Carry, and Holosun 407K/507K.
