Glock 43X MOS8 9mm Pistol Package with Aimpoint COA
$870.00
The Glock 43X MOS8 combines a slim, sub-compact frame with a factory-integrated Aimpoint COA enclosed red dot sight. Built on a Slimline polymer frame with a dedicated accessory rail and a 3.39-inch barrel, this 9mm handgun delivers a standard 10-round capacity optimized for concealed carry. The specialized A-CUT mounting system seats the premium 3.5 MOA optic directly to the slide, lowering the sight profile for natural alignment and an absolute co-witness with standard backup iron sights.
Description
Advanced Direct-Mount Optic System
The Glock 43X MOS8 (MPN: UX4350B01FRMOS8A4) represents a specialized engineering partnership between Glock and Aimpoint. Utilizing a proprietary A-CUT slide configuration, the included Aimpoint COA enclosed reflex sight fits directly into a machined dovetail interface on the slide. This eliminates the added height, weight, and mounting hardware of standard adapter plates, lowering the red dot axis for an intuitive sight picture and natural alignment under stress.
Slimline Frame Architecture
Engineered specifically for everyday carry comfort, the handgun pairs a sub-compact, single-stack slide width with a full-length Slimline grip profile. This design maximizes ammunition capacity and control while minimizing print profiles under standard clothing. The frame is constructed from a high-strength polymer compound and includes a built-in beaver tail to prevent slide bite during rapid strings of fire.
