Did it have a bayonet lug?
Hey LAZ!
It’s a semiautomatic but it looks like one of fully automatic machpistols that are popular in tge movies. Totally useless except for spraying bullets. It looks like the Ingram MAC-11. He had an extended magazine probably 30 rounds. I haven’t seen anything that says it was modified to be fully automatic. The Sheriff chose that description because the reporters who don’t know or care about tge differences would eat it up. He’s also a recent replacement for a more conservative Sheriff who tge liberals here didn’t like.
