In "Mad Max - Fury Road" they have a whole bag full of cool guns in the tanker truck. One of them is a Luger and I believe you can catch Mad Max shooting it in one of the action scenes. There's also a Broomhandle and (I believe) a Webley plus some other interesting guns.
The most interesting gun though is a scoped SKS they use to take out enemies at about 1000 yards...
