Gun Mounting Details
The Holosun C series (407c, 507c, 508t) are “mini” red dots intended to be mounted to full-size slide handguns like the Glock 19, Walther PDP, and Sig Sauer P320.
These red dots have the standard RMR footprint. This footprint has two posts on the front of the optic and two screws near the rear. This is one of the most common footprints for full size handguns, however, some do require an adapter plate for proper mounting.
This red dot will fit:
- Glock MOS (not 43X or 48, gun comes with RMR plate)
- Walther PDP (with Walther provided RMR adapter plate)
- H&K VP9 requires this adapter plate
- Sig P320 RX/Pro/AXG requires this adapter plate
- Sig P320 X-Five/M17/M18 requires this adapter plate
- CZ P-10 V4 requires this adapter plate
- S&W M2.0 requires this adapter plate
