Glock G45 Gen5 MOS 9mm Limited-Edition Aimpoint COA Combo — Factory-Installed 3.5 MOA Red-Dot, 31-Round Ready
This 2025 Glock G45 Gen5 MOS Aimpoint COA Combo pairs Glock’s crossover 9 mm pistol with the first-ever factory-installed Aimpoint COA enclosed red-dot sight. It is a limited, collectible release produced in collaboration with Aimpoint, distinguished by its nDLC-finished slide, Glock Marksman Barrel, and optic cut that seats the sight low enough for true co-witness with the included suppressor-height sights.

The G45 combines a full-size G17 grip with a G19-length slide, delivering 17-round flush-fit capacity while retaining compact handling. Glock’s flared mag-well and reversible magazine catch speed reloads, and ambidextrous slide-stop levers support left- or right-hand operation. This example ships with extended 31-round magazines, boosting capacity to 31+1 rounds straight from the box.
The slide carries Glock’s durable nDLC finish and both front and rear cocking serrations. A Glock Marksman Barrel features polygonal rifling and a recessed crown for enhanced accuracy and durability. Gen5 refinements—no finger grooves, improved trigger geometry, and enhanced internals—further modernize the platform.
Aimpoint’s COA optic is factory-mounted in Glock’s A-Cut MOS interface, positioning the sight lower than standard MOS cuts for a natural sight picture and true iron-sight co-witness. The enclosed-emitter design uses a 3.5 MOA red dot with 12 brightness settings (8 daylight, 4 NVD, plus extra bright). A single CR2032 battery delivers up to 50,000 hours of runtime, and the auto step-down feature conserves power when the sight is idle.
This is an early, low-production example of the 2025 Glock × Aimpoint collaboration, backed by its factory certification and distinguished by a Langdon Tactical backplate. Collectors and shooters alike will appreciate its rare status, turnkey optic, and Gen5 performance upgrades.
