Cimarron Old Model 1873 Help

[lostbird]

I just purchased a Cimarron Old Model 1873 45 L.C. with a 4 3/4" barrel. I would like to get some information about it. The revolver is advertised to be an exact duplicate of the original Colt Model 1873 SAA manufactured from 1873 until 1896 and the parts are interchangeable. I'm looking for a detailed video or written instructions on how to disassemble and reassemble it properly. The trigger is very rough and it needs an action job. A how to video of a DIY action job would also be very helpful. Any information or your experiences regarding this particular revolver would be very much appreciated. Thanks for your trouble.

Your best source of info, including on how to do trigger work is to buy the Jerry Kuhnhausen Shop Manual.
This was written as a training aid for new gunsmith students and covers EVERYTHING on gunsmithing the SAA.

Since Kuhnhausen trained gunsmiths for the factories, all the techniques are how Colt does it.
The info is good for the Italian SAA's also.

While you're at Brownell's, also buy the Colt SAA gunsmith screwdriver bits.
These will prevent tearing up the screw slots.

One of the things that made the Colt SA popular on the frontier is the simplicity of the gun. If you are at all mechanically inclined it is easy enough to disassemble and reassemble the revolver. However, you need to know what you are doing before you start stoning sears and notches. Let me suggest that you start by purchasing a set of Wolfe replacement springs and installing them, an easy ten minutes job. My guess is that this will largely cure your trigger problem. All you have to do to get to the two springs is remove the screws attaching the grip frame (both pieces) including the one located at the bottom of the grip. As previously suggested, use a proper screwdriver tip with square shoulder that fits. It is especially easy to bugger up the screw heads on Italian revolvers. They generally aren't properly hardened.
