Special Features

• The Aimpoint COA is an enclosed-emitter red dot with a 3.5 MOA dot and 12 brightness settings, including four night-vision-compatible levels, giving you a clear sight picture across a wide range of lighting conditions.
• The COA runs on a single CR2032 battery accessed from the bottom of the optic, rated for up to 50,000 hours of continuous use, with an auto step-down power management feature that preserves battery life without manual intervention.
• The 15-round factory Glock magazines use a metal double-stack body and are compatible with the standard polymer magazine catch, requiring no hardware changes to the pistol.
• The GMB barrel features enhanced polygonal rifling for improved consistency and wear resistance across high round counts.
• Precision-milled front slide serrations improve grip during press checks and manipulations in wet or gloved conditions.
• The built-in beavertail on the polymer frame raises the hand higher on the grip for a more consistent natural point of aim.

Practical Benefits

• The slim Slimline profile and 1.10-inch width make this pistol comfortable to carry all day in an inside-the-waistband holster without the bulk of a full-size frame.
• The factory-mounted Aimpoint COA means you can carry with a zeroed optic the day you take delivery, with no extra mounting hardware to source or zero to establish.
• The 15+1 capacity puts competitive round count in a subcompact frame, making this pistol ideal for everyday carry, backup duty use, and home defense without stepping up to a larger platform.
• The fixed co-witness sights remain usable if the optic is ever obstructed, giving you a reliable fallback without swapping any components.
