Continuity mistake: In the scene where Maggie goes to the restaurant with Bob, he offers her the case where the weapon is. Bob says, 'It's loaded'. Close inspection shows the clip chamber is empty (not loaded), and a cartridge clip is positioned beside the weapon in its tailored slot in the custom case. Maggie closes the case and says, 'I don't understand.' After Bob explains what she is to do, then leaves, Maggie opens the case again and suddenly there's a clip in the weapon (loaded) and another one beside it. The weapon was not loaded when she looked the first time.
Continuity mistake: When Maggie is given two seconds to wipe out the villains during target practice, the last cardboard cutout depicts a woman, and Maggie blows her head off. When we cut back to Maggie, she is holding her weapon from her hip and not from her head.
