The Glock A-Cut Aimpoint COA series guns have proven popular since their release, but the company is reportedly reining in consumer sales. 

The pistol maker debuted the concept in January, with G48, G43X, G19 Gen5, G45, and G47 models available. The COA, in turn, mounts into the Glock A-Cut via a wedge system that helps eliminate movement. The two companies developed the system jointly, and the pistol maker says it meets its 40,000-round endurance standard. 
 

While supplies of these new guns have never been plentiful enough to fully sate demand, it was widely reported via social media over the weekend that "all Glock COA models have been canceled for the civilian market indefinitely to fill military orders."

Although not discontinued outright, it would seem that the remaining consumer-facing supplies of COA-equipped guns in circulation are finite, at least for the time being. 

Glock has been tight-fisted with the COA models all year. 

We at Guns.com were loaned two COA-equipped Glocks, a G19 and a G48, for reviews. When we attempted to purchase them at the end of the test period, company representatives said they needed the pistols returned. This has not occurred in previous experiences after reviewing new Glock models over the past decade. 

On the upside, the exclusive agreement between Aimpoint and Glock on the COA lasts for 12 months and is expected to expire in early 2026. Other manufacturers such as CZ, Springfield, and S&W could then introduce competitive COA-equipped or compatible models if Aimpoint's manufacturing capacity enables the optic to be distributed outside of the Glock package. Aimpoint currently has a U.S. Patent (No.18/876,898) on the A-Cut pending.
