Description
If you've got an older or standard HK that never came cut for an optic, this EGW mount is one of the cleanest ways to run a red dot without sending the slide out for machining. It replaces the factory rear sight by sliding into the existing dovetail, so you get a solid optic platform while keeping the option to go back to irons anytime you want.
This specific plate (MPN 49507) is built for the non-optics-ready HK VP9, VP9SK, VP40, P30, P30L, P30SK, HK45, and HK45C pistols chambered in 9mm, .40 S&W, and .45 ACP. It carries the Trijicon RMR footprint, which also opens the door to a bunch of popular optics like the Holosun 407C and 507C series, the Trijicon SRO, and Swampfox models. That versatility is a big reason folks reach for this one instead of a single-optic plate.
How the HK Trijicon RMR Mount Goes On
Installation is about as straightforward as it gets. You drift out the factory rear sight, slide the EGW mount into the dovetail, snug the set screw against the bottom of the cut, then bolt your optic down with the included hardware. EGW recommends a drop of blue Loctite on the screws and torquing them to spec. No permanent alterations to the slide, which means resale value and the ability to revert to irons stay intact.
Why EGW's 7075 Aluminum Build Holds Up
The mount is machined from 7075 aluminum and wears a matte black hardcoat finish, so it shrugs off the recoil and holster wear that comes with regular carry and range time. At 1.780 inches long and 1.1 inches wide, it keeps a low, trim profile on top of the slide. It's a proven, no-nonsense piece of kit for anyone wanting a reliable optic solution on a pistol that didn't ship ready for one.
One important note: this is made for the standard, non-optics-ready HK models. If your pistol already came with an optics cut from the factory, you'll want EGW's optics-ready adapter plate instead.

Frequently Asked Questions
Which HK pistols does this EGW Trijicon RMR mount fit?
It's designed for the non-optics-ready HK VP9, VP9SK, VP40, P30, P30L, P30SK, HK45, and HK45C models chambered in 9mm, .40 S&W, and .45 ACP. The mount slides into the rear sight dovetail on these slides. If your HK already has a factory optics cut, this is not the plate you want.
What optics work with this mount?
The plate uses the Trijicon RMR footprint, so it directly accepts the Trijicon RMR and SRO. That footprint also fits the Holosun 407C and 507C series as well as compatible Swampfox optics. It's a nice way to keep your optic options open down the road.
Do I need to machine or modify my slide to install it?
No. You drift out the factory rear sight, slide the EGW mount into the dovetail, and secure it with the set screw and included hardware. There are no permanent alterations, so you can remove the mount and put your rear sight back on whenever you like.
Is any mounting hardware included?
Yes. The mount ships with two 6-32 flat head screws for the Trijicon RMR and one 6-32 x 3/16 set screw. EGW recommends a drop of blue Loctite on the screws and torquing them to spec during install.
