Gun Mounting Details
The Holosun 509T is a “mini” red dot intended to be mounted to full-size slide handguns like the Glock 19, Walther PDP, and Sig Sauer P320.
This red dot has a unique mounting footprint with a rail and an opposing clamp. It is similar to but different from the Aimpoint ACRO footprint. It also comes with an adapter plate for the common RMR footprint. This is one of the most common footprints for full size handguns, however, some do require an adapter plate for proper mounting. We recommend using only one adapter plate when possible.
This red dot will fit:
- Glock MOS (not 43X or 48, gun comes with RMR plate)
- Walther PDP 1.0 requires this adapter plate
- H&K VP9 requires this adapter plate
- Sig P320 requires this adapter plate
- FN 509 requires this adapter plate
- CZ P-10 V4 requires this adapter plate
- S&W M2.0 requires this adapter plate
