The Joker's Machine Pistol

The Joker's machine pistol was a favored firearm of his.

History
During the robbery of Gotham National Bank, the Joker used his machine pistol to shoot the bank's manager, which dropped him to the floor, alive but in pain.

He next used his machine pistol to shoot his bus driver thug in the chest, murdering him.

After Batman flipped the Joker's semi truck, the Joker crawled out in a daze and accidentally left off a short burst from his pistol as he tried to right himself.
