Continuity mistake: In the garage scene, 02 pulls a pistol from the guy he beat to the floor and stuffs it into his pants quickly as his girl starts trying to kick the guy on the floor. when he stuffed the pistol into his pants the grip was pointing to his right pocket. With the quick struggle the shot changes back to the pistol in his pants and now the grip is pointing towards his left pocket, and no one touched it.
Factual error: In the standoff between Meat and O2, Meat pulls the trigger to shoot O2 and his gun clicks - it is out of rounds. This is a common mistake: semiautomatic pistols do not re-cock after the last round is fired - the chamber remains open, so the gun will not click if the trigger is pulled again.
