Continuity mistake: In the scene where Sherlock is on the roof of the hospital with Moriarty, when Moriarty shoots himself in the mouth, when the camera shot quickly changes from a close up and Sherlock moves back, the gun disappears from Moriarty's hand (to the right of Sherlock). In the next shot of him, it's still in his hand.
