I heard on the radio 20 “guns”
*”guns” is my term. To me anything that has bullets is a gun whether it’s a rifle or AK=####.
“Federal officials say several long guns and handguns were removed from the home, including three 9mm handguns, a .357 revolver and several other rifles and shotguns.”
Then say ‘Twenty firearms’ unless you are certain that there are twenty guns.
All guns that use gunpowder are firearms but not all firearms are guns.
