The affidavit says Dixon also had pictures of himself on his Instagram holding a handgun with a "Glock switch," which can turn semi-automatic pistols and rifles into fully automatic weapons.

Such switches do for handguns what bump stocks do for rifles: They fire a hail of bullets with a single pull of the trigger. They are as tiny — only about 1 square inch — as they are deadly.

Glock switches are small devices that make handguns capable of firing multiple rounds in a few seconds. Now, Rep. Phillip Ensler is sponsoring a bill to ban them on the state level.
