In case you haven't encountered it before, there is the IMFDB (Internet Movie Firearms Data Base), patterned after IMDB. Almost any movie ever made that has guns in it, someone somewhere has slowed it all down and paused every scene and written down and catalogued each gun, which can be referenced by actor, movie, gun, etc. This even includes "non-guns" that have been used in an attempt to fool the audience.
