H&K VP9 to Holosun K/EPS/EPS Carry/407K/507K/SCS Carry Steel Adapter Plate
This plate is designed specifically for the VP9’s optics-ready slide and supports a wide range of micro red dots - including Holosun’s K-series, EPS, EPS Carry, 407K, 507K, and SCS Carry models.
With a thickness of just 0.085", this adapter keeps your optic low-profile and fast to acquire. It comes with custom M4 screws and clear torque specs for easy, confident installation.
Built from the same hardened steel as our other models, this plate is made to hold zero through thousands of rounds - even under harsh recoil and hard use.
H&K VP9 to Steiner MPS Steel Adapter Plate
For shooters who prefer the rugged, fully enclosed Steiner MPS optic, this plate offers a precise fit to the VP9 slide and a secure mount that won’t shift under pressure.
The plate measures 0.200" thick and includes all the hardware needed for installation. Like everything we make, it’s tested to hold zero and built to last a lifetime.
