Communities around the U.S. have seen shootings carried out with weapons converted to fully automatic in recent years, fueled by a staggering increase in small pieces of metal or plastic made with a 3D printer or ordered online. Laws against machine guns date back to the bloody violence of Prohibition-era gangsters. But the proliferation of devices known by nicknames such as Glock switches, auto sears and chips has allowed people to transform legal semi-automatic weapons into even more dangerous guns, helping fuel gun violence, police and federal authorities said.

The (ATF) reported a 570% increase in the number of conversion devices collected by police departments between 2017 and 2021, the most recent data available.

The devices that can convert legal semi-automatic weapons can be made on a 3D printer in about 35 minutes or ordered from overseas online for less than $30. They’re also quick to install.

“It takes two or three seconds to put in some of these devices into a firearm to make that firearm into a machine gun instantly,” Dettelbach said.

    Gun owner, pedant, and father of a trans man here. Did you just make a bigoted assumption?

    It’s a shibboleth.

    The distinction is simple, straightforward, widely taught, broadly known. Using it correctly is an immediate indication that one has acquired some very basic knowledge of the subject matter. Using it incorrectly is an immediate indication that they have not.

    If someone with a gun calls it a “clip”, I am immediately wary. They haven’t learned very much about guns, and certainly not from responsible instructors. They might have a gun in their possession, but they haven’t proved they are gun owners. Until I can determine their skill level, I won’t be turning my back on them.

    A “magazine” charges the firearm; a “clip” charges the magazine.

    That’s it. That’s the distinction. A magazine puts ammunition into the action of the gun, where it is fed into the chamber and fired. A clip is used to put ammunition into the magazine, where it waits to be fed into the action.

    It is one tiny little factoid about guns that immediately demonstrates the speaker’s familiarity - or ignorance - of the subject matter. It is a shortcut toward determining their credibility.
