Holosun HS507K-X2 2 MOA Dot and 32 MOA Circle Red Dot Sight

A: Hi Gary and welcome. You would need an optics plate. The Springfield Armory XD Model 3 utilizes the "OSP" (Optical Sight Pistol) footprint, which means it is designed to accept a wide range of red dot optics, primarily compatible with the Trijicon RMR, Leupold DeltaPoint Pro, and Docter sight footprints, allowing for customization with different mounting plates to fit various optics from brands like Vortex, Holosun, and Burris. The M&P SCS would be a direct Slide fit: https://www.budsgunshop.com/product_info.php/products_id/150646/holosun+scs-mp2+reflex+sight ----------- Cheers, stay safe and enjoy!

A: The XD® Mod.3 OSP™ features a factory-milled slide designed to accept a variety of popular red dot optics, ensuring quick target acquisition and improved accuracy. OSP™ plates, available for purchase in our store, allow for easy customization to fit RMR®, DeltaPoint Pro and Docter footprints.

A: Hi Timothy and welcome. Yes, the Holosun HS507K-X2 1x Red Dot will be a direct fit. Cheers, stay safe and enjoy!

A: Yes but depends on what optic cut is on your frame. If rmsc I recommend the Viridian RFX11.

A: Hi Duke and welcome. Yes, the Holosun HS507K-X2 fits the Glock 43X MOS, but how it mounts depends on which factory slide cut your pistol has. Standard / Original Slimline MOS Cut (4-Post Lugs): If your Glock 43X MOS has the traditional factory slide cut with four protruding recoil lugs (common on models manufactured prior to late 2025), you cannot mount the 507K directly. The slide's rear posts will block the housing, so you must use an adapter plate (such as those from DPP Titanium via Freedom Gorilla or C&H Precision). Revised MOS-K Cut (2-Post Lugs): On newer Glock 43X MOS variants featuring the updated MOS-K slide cut (which omits the rear recoil lugs), the Holosun K-footprint optic drops straight on with no adapter plate required.

A: Hi Joseph and welcome. Yes, the Holosun HS507K-X2 will mount directly to the Sig 365X without an adapter. Cheers and stay safe!

A: Yes, no adapter needed

A: Yes, the Holosun HS507K-X2 (UPC: 810047071211) mounts directly to the SIG Sauer P365X slide without an adapter plate. The SIG Sauer P365X features a factory optics-ready cut designed for the Shield RMSc footprint. Holosun's K footprint is a modified variant of this layout that matches the P365X slide perfectly, allowing you to bolt the optic straight to the pistol with no additional modifications. Installation Details • Holosun HS507K-X2: Included Hardware: You should use the mounting hardware provided in the Holosun HS507K-X2 box rather than any stock factory screws to ensure proper thread engagement and length. • Torque Spec: When securing the optic, it is generally recommended to apply a small drop of blue threadlocker (such as Loctite) and torque the screws to 15 inch-pounds to prevent them from backing out under recoil.

A: For the most part, yes!

A: Hi David and welcome. Yes but depends on when your Glock 48 was made. • Original Slimline MOS Cut (Launch through most of 2025): The slide features four recoil posts (front and rear pairs). Because the Holosun 507K uses a K-footprint that only fits the front two lugs, you will need an adapter plate—such as those from C&H Precision, AltitudeCraft, or Monstrum—or you must carefully file/modify the rear two posts. • Revised MOS-K Cut (Late 2025 onward): Newer Glock 48 MOS slides feature an updated two-post cut where the HS507K-X2 will mount directly to the slide with no adapter plate required. Cheers and stay safe!
