❓ Frequently Asked Questions (FAQ)

Will this adapter plate fit my Glock MOS slide?

Yes — as long as your Glock MOS slide uses an RMR footprint, this plate will allow you to mount the Holosun 509T directly.

Is this plate compatible with the Holosun 509T ACSS Vulcan?

No. This specific plate does not support the 509T ACSS Vulcan variant. Please check our site for a compatible option.

Can I use this with a ZEV slide?

Only if the ZEV recoil posts are removed. The steel plate is not designed to clear ZEV’s threaded post system out of the box.

Does it come with all the mounting hardware?

Yes. You’ll receive all necessary screws and an Allen key for a complete installation — no extra purchases needed.

What makes this plate different from aluminum versions?

Steel offers superior thread strength, durability, and resistance to stripping or loosening under heavy recoil. It’s a better long-term option for serious shooters.
