Systems that actualy emulate Western movies?

I haven’t cracked my copy of Western City for a while and it’s in storage now, but it seems a good fit for a narrative game exploring the classic themes of Westerns. Or running Support Your Local Gunslinger, whatever you’d prefer.

Another option is to go full Magnificent Seven Samurai and look at Oriental Adventures. The 3.0 version had decent "quick draw" mechanics (called "iajutsu focus"), and rules for "taint" that could be used for the cowboy code.
