DPP Titanium Adapter Plate for Glock 17 19 MOS Holosun 407K/507K - Low

Our review of the DPP Titanium Adapter Plate finds it is aimed at shooters who want a lightweight, corrosionproof mounting solution for specific Glock MOS slides and Holosun mini red dot models. The single biggest reason to buy is the combination of aerospace grade titanium construction and a one piece design that keeps a secure zero while adding almost no height to the sight plane. Install is straightforward and the included high-strength Torx screws and labeled hardware make getting the optic mounted quick for range or carry pistols.

Key Features

• Precision machining: CNC machined from 6AL4V aerospace grade titanium for consistent fit and long term durability.
• Low profile: Ultra low profile and lightweight design keeps the optic close to the slide for minimal sight offset and a natural cheek weld.
• One piece security: One piece plate holds the optic securely to maintain zero under recoil and regular use.
• Complete kit: Installation hardware and tools are included with high-strength alloy steel Torx screws for a tidy, reliable install.
• Model compatibility: Custom made to fit Glock 17, 19, 22, 23, 34, 35, 41 and 45 MOS with Holosun 407K, 507K, EPS Carry, EPS and RomeoZero footprints.
• Support and warranty: 7x24 technical support plus a lifetime warranty for long term peace of mind.

Who It's For

This plate is best for owners of compatible Glock MOS models who plan to mount a Holosun 407K, 507K, EPS Carry, EPS or RomeoZero and want a low added profile and corrosion resistance. It suits competitive shooters, instructors, and carry users who value a secure, lightweight mount that does not add bulk.

Those who own Glock 43X or 48 MOS slides, aftermarket cut slides, or optics that use a different RMSc footprint should look elsewhere, since the plate is not compatible with those variants or other non-listed footprints.

Pros & Cons
