A few months ago, the Military and Police Forces of Santa Catarina, Brazil, posted a Facebook video of an officer describing how an improvised 12 gauge sledgehammer would be fired. Like many home built weapons, the action is a simple spring loaded design that uses the handle as a barrel. The user unscrews the tube handle, places a single shell into the “chamber”, screws it back on to the head of the tool and cocks the firing pin.
The design seems simple but effective, hiding the weapon in the palm of a “laborers” hand.
Be safe guys.
