Glock with Autosear Switch Demonstration; Illegal Shipments in Chicago

Some discussion about the practical use of this modified weapon (or use for fun) does not discuss the accuracy of the weapon or wear and tear on the weapon.

According to RECOILtv, the switch concept originated in Austria when military personnel requested that Glock Austria create the switch for the military, but the switch is not sold to the public. There are fake products that illegally imprint the GLOCK logo on the switches. According to the ATF, the relatively simple, albeit illegal, device allows a conventional semi-automatic Glock pistol to function as a fully automatic firearm. The switch is classified as a machine gun under federal law.
