Glock 18 & 18C Machine Pistols: How Do They Work?
The Glock 18 and 18C are select-fire machine pistols developed for military and law enforcement. The 18C features a compensated barrel and lightened slide to manage its high rate of fire (1100-1200 RPM). Key internal differences, like higher slide rails, prevent Glock 18 slides from fitting standard Glock 17 frames to deter illegal conversions.
