GLOCK COA Model Guide: Features, Benefits, Where to Buy Now

GLOCK’s collaboration with Aimpoint for the COA (Compact Optic Adapter) model has sent ripples through the firearms community. This factory-ready red dot solution blends reliability with cutting-edge design. 

Unveiled at SHOT Show 2025, the GLOCK COA package equips select 9mm GLOCK pistols with Aimpoint’s COA optic, mounted via the innovative A-Cut interface. Available on models like the G19 Gen5, G43X, G45, G47 and G48, this setup delivers unmatched durability and performance for competitive shooters, concealed carry holders and law enforcement alike.

The COA’s appeal lies in its seamless integration. Unlike aftermarket optic cuts, the A-Cut system mounts the Aimpoint COA deeper into the slide. This ensures rock-solid stability tested to GLOCK’s 40,000-round endurance standard. The optic’s low-profile design also reduces bulk, making it ideal for concealed carry and allowing co-witness with standard-height iron sights. 

With a 50,000-hour battery life and a compact yet wide viewing window, the COA enhances target acquisition without sacrificing holster compatibility.

GLOCK COA Rumors

Recent rumors suggest GLOCK may be pulling COA models from the commercial market to prioritize production for potential military contracts. Firearms enthusiasts are buzzing on platforms like Glock Talk and AR15.com, noting that GunBroker has substantial inventory of COA-equipped pistols. With GLOCK reportedly canceling commercial orders and halting new shipments for up to two years, now may be the time to secure one before supplies dwindle.

The COA’s benefits extend beyond its robust build. The optic’s enclosed design protects against water, dirt and impact. It can withstand submersion up to 82 feet. Side-accessible windage, elevation and brightness controls offer 12 settings for versatility in any lighting condition. Priced between $1,002 for the G43X and $1,165 for the G19, the GLOCK COA package undercuts many aftermarket red dot setups, delivering Aimpoint quality at a value. On the range, shooters report faster draws and clearer sight pictures, making the COA a game-changer for defensive and competitive applications.

For firearms owners, the GLOCK COA model represents a leap forward in factory optics integration. Its durability, ease of use and cost-effectiveness make it a standout choice. However, with whispers of limited availability growing louder, enthusiasts should act quickly. Checking GunBroker or local dealers for remaining stock could be the key to owning this innovative pistol before it becomes a government exclusive.
