Mounting HE507K-GR X2

[MickGIS]

I'm having trouble finding an mounting (adapter) plate to install a Holosun HE507K-GR X2 on my M&P9 M2.0 OR Spec Series Pistol Kit. None of the plates in the S&W SCREW & PLATE KIT (part #3011897) that came in my Pistol Kit, indicate they would work with the Holosun.

I've looked at plates from these sources but none work for this setup:
C&H Precision
EGW Gun Parts
Outerimpact

Any ideas?

Sent you a PM also. Do you own the Holosun K already? The K is designed for single stack pistols where the 507C is designed for double stacks like your pistol. I have one in green with the Primary Arms ACSS reticle on my XD-M Elite and love that design. Larger window too. Primary Arms has a 12% off sitewide right now I believe.

Hey here's a good resource:

Footprints/Mounting Standards on Red Dot Sights - Optics info

It lists many red dot footprints and at this subpage:Holosun 507C X2 Footprint - Optics Trade Blog

It states:
"Holosun 507C X2 features the Trijicon RMR mounting standard."

And there is a plate included with my pistol kit to mount red-dots with that footprint.

The OP's is a 507"K": the excellent link above (THANKS, BTW!) specifically mentions these needing a modification of the Shield RMS/SMS mount, which seems to require removing material from the pistol...

I'd suggest further investigation.

Good Luck!

Yes, I changed to the Holosun HS507C X2 which uses the Trijicon RMR mounting standard and the S&W M&P Pistol kit came with a S&W Screw & Plate Kit, part #3011897. This kit contains a plate to mount the Holosun HS507C X2.

I ended up getting a Holosun HE508T-GR X2. It's similar to the Holosun HS507C X2 but has a flat top and a titanium housing both have an RMR footprint. Here's a website that details the differences:
