Ithaca Mag 10 Supreme grade. Pretty early production, like 1500 range.
My BIL used to be a Texas DPS trooper. They were issued an Ithaca Mag-10 Roadblocker.
They kept it loaded with slugs to stop vehicles with.
He said he didn't know if they would bust engine blocks..... but they'd play hell with everything else under the hood ...... and the passenger compartment !! LOL
