Its been awhile since this subject came up (well except for war movies of course)--I think it was on the old discussion board. Lots of new folks since then, and its due for a reminder.
I'm prompted to post this because American Movie Classics has been running the movie "Charade" in heavy rotation lately. In the climactic scene Walter Matthau chases Carey Grant and Audrey Hepburn, Luger in hand. The Luger plays prominently, two extended scenes and a gratuitous closeup.
