Command Arms Accessories has introduced a shot counter for Glock users. The shot counter counts split times, as well as total round count for maintenance. From Military.com’s KitUp!:

Command Arms Accessories USA is now offering a high-tech shot counter for several Glock pistol models.

The Secubit Gun Shot Counter is the “ultimate upgrade for shooters who want to improve split time (time between shots), increase shooting accuracy, and keep a full record of shot count for maintenance,” according to CAA’s website.

“The GSC is smallest counting and recording device available—small enough to fit into the grip pocket of a Glock … while preserving grip ergonomics and carrying comfort.”

The GSC detects number of shots fired by sensing vibration and shock and will record up to 500,000 shots.
It shows exact date and time, computes time between shots, or split time, and rate of fire to provide you with the necessary data to improve your accuracy, according to CAA’s site.

The GSC fits the Glock 17, 18, 19, 22 and 23 – Gen 1-3.

It retails for $100 and includes advanced software that automatically collects and stores gunfire data, making it available to an Android device or a PC through a USB cable.

The US Army has been working on a shot counter for issue carbines since 2005, at the latest. Whether CAA’s development has been influenced by Army research, or whether Army research will be influenced by the Secubit counter is unclear.
