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. Placing the fire selection switch in between the top and bottom positions renders the gun safe. Image File history File links G18_mag. ...

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.

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 no finger grooves or thumb indentations on the grip and no weaver rail on the dust cover

Variants

The GLOCK 18C compensated model, despite it's 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. Compensator can refer to: A muzzle brake, used to counter the recoil of a firearm, or to prevent the muzzle from climbing during rapid fire A device that offsets or counterbalances a destabilising factor: See Buoyancy compensator, Static VAr compensator, Heisenberg compensator, Lead-lag compensator This is a disambiguation page...
