Performance & Applications
The GLOCK 23 GEN4’s specifications and design translate directly into real-world performance for specific applications. Its .40 caliber chambering and compact dimensions make it exceptionally versatile.
For law enforcement and duty carry, the pistol offers a proven track record of reliability under stress.
