About the Glock 18
The Glock 18 is a select-fire machine pistol variant of the Glock 17, capable of both semi-automatic and full-automatic fire at approximately 1,200 rounds per minute. Developed in 1986 at the request of the Austrian counter-terrorism unit EKO Cobra, the G18 was Gaston Glock's second pistol design. Externally nearly identical to the G17, the G18 features a fire selector switch on the left rear of the slide - up for semi-automatic, down for full-automatic. Despite the visual similarity, the G18 slide and G17 frame are not interchangeable due to internal modifications required for the select-fire mechanism. The G18 accepts standard Glock 17 magazines but is commonly paired with extended 19, 24, or 33-round magazines to better accommodate its high rate of fire. An improved compensated variant, the G18C, was introduced in 1996 with four barrel ports and corresponding slide cuts to reduce muzzle climb during automatic fire. Sales are restricted exclusively to military and law enforcement agencies worldwide; no transferable examples exist on the civilian market.
The Glock 18 gained legendary status largely through pop culture despite being one of the rarest production handguns in the world. Featured prominently in films including The Matrix Reloaded, Terminator 3, and Skyfall, as well as in the Counter-Strike franchise where the 'Glock-18' is the default Terrorist-side pistol, the G18 is arguably more famous in fiction than in any real-world conflict. The irony is that most people who recognize the name will never see one in person - there are zero transferable examples on the U.S. civilian market, and Glock's official policy states they will never sell them commercially.

Gaston Glock originally developed the G18 partly as a durability testing platform - the extreme stress of full-automatic fire allowed rapid assessment of component wear, heat resistance, and service life that semi-automatic firing could never replicate. The fire selector is a simple sliding switch on the left rear of the slide, positioned where it can be operated by the shooter's thumb. At 1,200 RPM, a standard 17-round magazine empties in under one second, making extended magazines essentially mandatory for practical use. The G18C compensated variant (1996) features progressively larger keyhole-shaped ports machined into the barrel and matching slide cuts, directing propellant gases upward to counteract muzzle rise. Despite its fame in movies and video games, the G18 is exceptionally rare in real-world use, with most operators preferring submachine guns for automatic fire roles.
This is a variant of the Glock 17.
