Glock 18 & 18C Machine Pistols: How Do They Work?
The Glock 18 and 18C are select-fire machine pistols with a unique selector switch for semi-automatic or full-automatic fire. The 18C incorporates a ported barrel and lightened slide to mitigate muzzle flip and improve controllability during automatic fire. Understanding the internal mechanism, particularly how the slide interacts with the sear in full-auto mode, is key to its operation.
