Frequently Asked Questions

What is the Glock 45 COA and why is it significant?

The Glock 45 COA is a Gen 5 pistol featuring a Glock 19 slide on a Glock 17 frame, equipped with a factory-milled slide for an Aimpoint ACRO optic. It's significant because it offered a highly desired, integrated optic solution directly from the factory, which has since been discontinued.

Why was the Glock 45 COA discontinued?

The Glock 45 COA was discontinued and removed from the commercial market primarily to fulfill contracts. This coincided with broader announcements from Glock about discontinuing their Gen 3, Gen 4, and Gen 5 pistol lines.

What issue did the presenter experience with the Aimpoint ACRO on the Glock 45 COA?

The presenter experienced an issue where the Aimpoint ACRO's reticle would disappear during recoil. This was resolved by replacing the original battery with a Procell CR2032 battery, as recommended by Aimpoint.

What is Aimpoint's recommendation for battery issues with their optics?

Aimpoint suggests using Procell CR2032 batteries, available on Amazon, as they lack a bitter coating found on some other batteries. This coating can sometimes interfere with the delicate connections within their compact optics.
