The Glock 18 is a handgun manufactured by Glock. It is much like a Glock 17 with a fire selector switch on its slide that enables it to fire in semi-automatic or fully automatic modes. Rotating the switch toward the bottom of the frame allows for fully automatic fire, while rotating it to the top switches the gun to semi-automatic. bvg

The Glock 18 appears identical to the Glock 17, with the addition of the fire selector. However, the internal dimensions of the main parts of the Glock 18 are slightly different from the Glock 17, and are not interchangeable. This was done by Glock so that the Glock 17 could not be considered a semi-automatic version of the Glock 18; rather they are two separate pistols. Some countries and jurisdictions have laws that place special restrictions on semi-automatic versions of fully automatic weapons, and if the Glock 18 were identical to a Glock 17, the Glock 17 would fall under those laws and be unavailable in those jurisdictions.

The Glock 18 is in the U.S. a law enforcement-only pistol that uses standard Glock 17 magazines, holding 17 or 19 rounds. It is sometimes used with special 31 or 33-round extended magazines, but this configuration is less common. There are known to be a few Glock 18s privately owned in accordance with the National Firearms Act.

[edit] Variants

Early version of Glock 18C, with three compensator cuts on its barrel, which extends past the frame rather than integrating into a slide with cutouts, as on later versions. Note also the lack of finger grooves or thumb indentations on the grip and lack of an integrated Weaver rail on the dust cover

The Glock 18C compensated model, despite its name, has a ported (not compensated) barrel. Two oblong cuts are made in the top of the barrel with matching cuts in the slide to direct some of the gases from the muzzle to counteract muzzle climb in automatic fire.
