When did this ‘long gun’ term enter the vocabulary? Weird
Anyways, here's what wikipedia has to say about"long guns"
A long gun is a category of firearms and cannons with longer barrels than other classes. In small arms, a long gun is generally designed to be fired braced against the shoulder, in contrast to a handgun.
Kali is Dim Central, and assault weapons and machine guns are banned, so ithey must be merely long guns.
