The Atlanta Police Department ordered and started receiving 2,300 Glock 22 Gen4 service pistols. The department-wide transition to Glock began mid-July and will continue through April 2014.
The Atlanta PD conducted a full year of extensive testing before selecting the Glock pistols based on the product's reliability. The SWAT team adopted the Glock 21 Gen4 pistol due to mission-specific requirements for .45 ACP, according to Glock.
