Own a musket for home defense, since that's what the founding fathers intended.
Four ruffians break into my home. "What the devil?" As I grab my powdered wig and Kentucky rifle. Blow a golf ball size hole through the first man, he's dead on the spot. Draw my pistol and fire at the second man, miss and hit the neighbors dog because it's smoothbore. I have to resort to the cannon mounted at the top of the stairs. "Tally Ho Lads!" Grapeshot shreds two men, the blast and shrapnel set off car alarms in the neighborhood. Fix bayonet and charge the last terrified rapscallion, he bleeds out waiting for paramedics to arrive since triangular bayonet wounds are impossible to stitch up.
Just as the founding fathers intended.
