The Glock 18 Machinepistol
The tenifer-coated and polymer-framed semi-automatic handguns of Gaston Glock are well
known and loved. A lesser-known Glock design is the select fire G18 machine pistol. In fact,
it’s so underplayed; Glock USA doesn’t even list a single reference to it on their website.
The original G18 was a standard Glock 17 with a few “slight” modifications. These included a
select-fire lever on the left rear of the slide that switched between semi-auto and full auto.
The switch actuated the modified sear and trigger to allow the firearm to achieve full auto
cyclic fire. With the lightweight of the firearm overall (22.04 ounces unloaded) the short
action of the breech’s movement was accomplished very fast. This gives the G18 a cyclic rate
of fire of up to an amazing 1300 rounds per minute as long as the ammo holds out. Keep in
mind that the old 1920s classic Tommy gun and the modern AK47 have a cyclic rate of
about 400rpm, and you understand what a chainsaw the G18 really is.

Nice….I just wish that Glock had a thumb switch saftey. I have had several and carry concealed, and hate the feeling of the Glock because I place it in the front belt area and have a fear my twig and berries are at risk always.
