What was the gun model used in "The Interview" and what other movies have used it?

Sorry if I'm not posting the right question in the right place, but please let me know.

I tried looking all over (Google, Wikipedia, IMDB, etc...) for the answers to what the model the gun character Sook Yung Park in "The Interview" (played by actress Diana Bang) was using in the scene where she and Seth Rogan are locked in the broadcasting room, and she shoots through the door.

Does anybody know what model gun this is and what other films have used it?

I also want to know if there's a different awesome gun model used in a scene that was unforgettable to you.

Reason I'm asking is for art purposes.
