Glock 45 Aimpoint COA First Impressions
Glock 45 A-Cut COA Combo: The Ultimate Crossover Pistol with Aimpoint Red Dot
Introducing the Glock 45 A-Cut COA Combo
Glock’s latest innovation, the 45 A-Cut COA Combo, is a game-changer for tactical shooters. This “crossover” model features a seamless integration with the Aimpoint COA red dot sight—no mounting plate required. Designed for precision and durability, this pistol is built to meet the demands of professional operators.
What Makes the COA Special?
The Aimpoint COA (Combo A-CUT) is a compact, fully enclosed red dot sight developed for military use in extreme conditions. Glock’s collaboration with Aimpoint ensures a direct-mount system, eliminating the need for adapter plates. The sight locks into a slide recess at the front and secures with two screws at the rear.
Key Features of the Glock 45 A-Cut COA
- Hybrid Design – Combines the compact slide of a G19 (4.02″ barrel) with the full-size frame of a G17.
- Glock Marksman Barrel – Enhanced polygonal rifling for superior accuracy.
- Ambidextrous Controls – Slide release on both sides for left- or right-handed shooters.
- No Finger Grooves – A smooth grip front for better customization.
- Flared Magazine Well – Faster, smoother reloads.
Shooting Impressions: Does It Live Up to the Hype?
Testing the Glock 45 COA confirmed what we expected—this is a refined, high-performance pistol. The ergonomics are superb, making it easy to handle even for shooters accustomed to other platforms. The Aimpoint COA red dot provides rapid target acquisition, though the low-profile iron sights may not co-witness perfectly.
What We Loved:
- Exceptional ergonomics—arguably one of the best Glocks ever.
- Seamless Aimpoint COA integration (no plate needed).
- Reliable performance with improved accuracy.
What Could Be Better:
- Iron sights are too low for optimal co-witnessing.
- Grip size may not suit everyone—try before you buy.
Glock GTL II Tactical Light: The Perfect Companion
Our test model included the new GTL II light, which integrates flawlessly with the pistol’s profile. With 600 lumens (standard and strobe modes), it delivers ample illumination without blinding the user. The CR123A-powered light is a significant upgrade over previous models.
