Revolvers with silver frames and black cylinders and barrels are pretty common in western films if you really pay attention.

@Chomusuke145 I'm aware of those old Spaghetti Westerns, but a lot of Colts had regular wooden grips, not bone, making Chris Larabee's Peacemaker kinda rare. Also, if you watch the movie "Man Without a Star 1955" you'll notice that Kirk Douglas' gun has an iron frame and worn parts that look like iron details.

I love that show.
