Special Features

• The G45 Gen6 crossover design combines a compact slide with a full-size frame, giving shooters full-grip ergonomics and magazine capacity in a slightly shorter overall package than the G17.
• The A-CUT interface integrates the Aimpoint COA directly into the slide using a front hook and rear wedge dovetail system, removing the need for adapter plates and keeping the optic mounted as low as possible to the bore axis.
• The Aimpoint COA features 12 brightness settings, including four night-vision-compatible levels and eight daylight levels, with tactile side-mounted buttons operable with gloves.
• The COA runs on a single battery rated for more than five years of continuous use, with a side-loading battery tray that allows replacement without dismounting the optic.
• The sealed COA housing is rated submersible to 25 meters, protecting the optic from water, dust, and field contaminants during active duty or outdoor use.
• The RTF6 frame texture extends across the thumb rest areas beyond the traditional grip zone, providing a more secure hold across varied hand sizes and grip angles.
• The flared magwell supports faster magazine changes under stress or during competition stages.

Practical Benefits

• The crossover platform gives you the control advantages of a full-size grip while the compact slide trims overall length, making the G45 a natural fit for both open carry and duty holster use.
• Competitive shooters running optics divisions gain a factory-zeroed dot that eliminates setup time and delivers consistent performance from the first round.
• The three included 17-round magazines provide immediate range-ready capacity without additional purchases.
• The ambidextrous controls and interchangeable backstraps let you configure the pistol to your exact grip preference without sourcing aftermarket components.
• The nDLC slide finish resists corrosion and wear through regular draw cycles, holster use, and extended training sessions.
• Whether you carry professionally, train frequently, or run the pistol for home defense, the G45 Gen6 transitions across all three roles without compromise.
• If you want a factory-complete crossover 9mm that delivers an integrated red dot, full-capacity handling, and duty-grade durability in one purchase, the Glock G45 Gen6 with Aimpoint COA puts all of that in your hands immediately.
