will this fit my Glock 20 gen 5 MOS for a holosun 407c X3

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on July 24, 2026

This adapter plate would not be compatible with your Holosun 407C. The 407C uses the RMR footprint. The correct plate would be MPN: 74013, found linked below:
