For those interested in more 'modern' weapons, my most frequently encountered weapons with cinematic heritage tend to be the various trapdoor rifles (usually 1873-1884). On the one hand, they were of course the actual weapons used in the west, which was formerly a very hot subject of interest, although cooling lately.
On the other hand, as the last of the sidelock, hammer-fired rifles, they conveniently could fire cartridge blanks but be mocked-up to look like flintlocks.
