Continuity mistake: When Maynard is teaching Tony to shoot a gun, Tony fires three shots first. The gun's chamber closes as usual (meaning the gun still has ammo). We see a shot of Maynard, then flick back to Tony and the chamber is now open (meaning the gun is out of ammo). Tony then fires three more shots from an apparently empty magazine before being told to reload. (01:26:40)
