“Alledgedly, they may have used “switches, a small device that turns semi auto into full automatic weapons...”. Uh, where can the be gotten ? Bass Pro Shops?”
These are Glock switches they require no major gunsmithing to install. They fit on the base end of any Glock handgun you do a basic field strip of the slide stick it on the buttend and reinstall the slide the switch then has a left / right position one way the sear us active and semi automatic as normal operation. The other way has a depress arm that pushes down the striker pin sear so when the slide comes back to battery the striker pin is let go automatically setting off the next round as long as the trigger is fully depressed. The switch itself is a NFA 1986 machine gun and can only be possessed by law enforcement of military users legally its a huge federal level felony to even possess one and each one is a 20+ year fed offence.
They are available from aliexpress or Alibaba via international mail or people 3D print them. DO NOT go to Alibaba looking for them unless you want to end up on someone’s watch list. People use VPN or the dark web if they know what they are doing. So yeah they are super easy to get, use and are common in street culture. One of my lawyers has a case right now where the guy is a cartel underling he got caught with a dozen switches and boxes of 100 round drum mags he is looking at effectively life in prison for it. So that’s the other source the cartels sell them on the street to our native thug culture as well.
Owwwww. You in trouble now. Thanks. :)
