Bad

During the scene in which Kalinda opens a case showing Diane and the others in the conference a collection of guns that were purchased within two miles of their office, Diane is given a gun to hold. Although Diane is timid around guns, showing a lack of experience with them, she still holds the gun properly; more specifically, instead of holding the gun with her finger through the trigger guard like most people do, she has her index finger pointed along the side, just above the trigger guard, which is the proper way to hold a firearm. One must never put their finger through the trigger guard unless they intend to actually fire the weapon. This could indicate that Diane has more experience and comfort about firearms than she lets on, or an error by the director wherein the actress playing Diane, Christine Baranski is subconsciously employing her own training and firearm safety.

When Kalinda clears the weapon after Diane changes her mind and gives it back to her, Kalinda pulls the slide back and allows it to close with the magazine still inside the gun. Not only is this different from the way she demonstrated earlier in the show, but clearing the weapon in that manner would still leave a round chambered if one was still left in the magazine.
