The H&K 51000381 mounting plate is a precision-machined optics adapter built for shooters who've equipped their HK VP9 series pistol with an optic-ready slide. If you run a reflex sight on your VP9 OR, VP9L OR, VP9A1 K, or VP9A1 F, this plate delivers the all-steel foundation your setup needs. It's a no-compromise piece: billet-machined from ordnance-grade steel, finished in durable Cerakote, and made in the USA. Installation is straightforward—the plate ships with two T20 Torx Plus screws sized to secure the mount directly to your slide.
This isn't a generic aluminum adapter or a compromise fit. Every plate is CNC machined from solid steel, then deburred and tumbled for a clean, professional appearance. The Cerakote finish protects against wear, corrosion, and the rough treatment optics mounts take in the field or at the range. Whether you're setting up a carry gun with a Holosun K-series optic or a duty pistol ready for duty, this plate ensures your sight stays put and returns to zero.
The H&K mounting plate solves a specific problem for VP9 owners: finding an OEM-quality adapter that fits HK's engineering standards. This plate integrates directly with your slide's mounting surface, giving you the rock-solid platform a modern optics-ready pistol demands.
