I think the 20mm cannons are illegal now, classed as "destructive devices"... But guys used to have surplus Lahti 20mm and shoot 'em. You're right, Kris, it's a Desert Eagle, nothing illegal about them I think in any state, though some states have (illegally) restricted and licensed ownership of handguns.
Yeah, OT for sure... But just to add the 50AE is gentler to shoot in a gas-operated semi-auto like the Desert Eagle than a revolver, but I've found it's beyond my comfort limit anyway. Just jokiing about "puny". 🙂
