Hunt showdown Uppercut for KM 

This is wrong. You should only be able to rotate the cylinder on half cock. Otherwise, nice model.

badass, as @sci3568 said for realism make it more interesting but badass still from England still badass

1:15 ejector rod not extractor. Ejectors kick the empty cartridge/hull completely out into the air, like the "Romero 77". Extractors pull them out of the chamber to be ejected by another part or manually by hand, like the "Caldwell Rival" 78.

Just a suggestion, for the fake cartridges, you should print them in red for the American market. Here in the US we have fake cartridges called snap caps. They are always usually a red color.

You should see if you could do the Cadwell chain revolver. And make it really work.
