 FAKE: Leo gives Sam his gun in the basement. She aims at him. Then  he says he would never give her a loaded weapon and tells her he  took out the magazine. But when Sam puts the mag in and loads the  gun (pulling back the slide) you can clearly see a bullet flying out  of the shell ejection. So that means there was a bullet in the  barrel all along and she wouldnt have needed the mag at all which  tells us that Leo is not a professional or more likely that the crew  screwed it up.
