Continuity mistake: In the final shootout scene, Jeff is holding a Colt 1911 style pistol, which is single action only. This means that it must be cocked prior to firing it the first time, or squeezing the trigger will have no effect. When he is holding his hands up, the hammer is cocked back like it should be, but when the camera zooms in on his face, the hammer is down. When the camera backs out again, the hammer is cocked again.
