Get the Heatermug. A gun, not always loaded, typically a 9mm hand gun. Used if loaded to shoot(DUH) Unloaded good for a bluff.
Dally: We can't walk alone at all. I started carrying a heater...
Ponyboy: Dally! You kill people with heaters!
Dally: You kill 'em with swtichblades too don't ya kid? Don't worry it ain't loaded. I ain't aimin' to get picked up for murder. But it sure does help a bluff.
