I saw the movie between 2007-2009, i believe.
All I really remember of the movie, is a scene where there is a guy. His kind of girlfriend had been kidnapped or some kind, and then he takes two silver pistols out of his drawer, and rescues her in some kind of warehouse.
I think that the girl was cheating on her boyfriend, with the guy I was talking about in the beginning of the post.
Hitman?
