Holosun 509T to Glock MOS Adapter Plate - Full Size Compatible

The NF GLK-OP-509T-FSMOS adapter plate bridges the gap between Holosun 509T red dot sights and Glock full-size MOS pistols. This precision-machined mounting solution eliminates the need for gunsmithing while maintaining zero retention through thousands of rounds.

What Makes This Different

This adapter plate features CNC-machined aluminum construction with precise tolerances that match factory specifications. Unlike universal mounting systems that require modification, this plate drops directly into Glock MOS cuts without permanent alterations. The low-profile design maintains proper sight height while providing rock-solid optic stability.

Key Features

• Direct-fit compatibility with Glock 17, 19, 22, 23, 26, 27, 31, 32, 33, 34, 35 MOS models
• Precision CNC-machined 6061-T6 aluminum construction
• Holosun 509T specific mounting pattern and screw configuration
• Low-profile design maintains proper sight picture alignment
• Mil-spec Type III hard anodized finish resists corrosion and wear
• Includes mounting hardware and thread-locking compound
• Zero permanent modifications required to firearm

Field testing demonstrates consistent zero retention across temperature extremes and high round counts. The plate handles recoil impulses from standard pressure 9mm through hot .40 S&W loads without shift. Competition shooters report maintained accuracy through extended match schedules, while duty users appreciate the quick installation process that doesn't void manufacturer warranties.
