Cimarron Frontier Hammer Roller Don't Roll

[CatBacker88]

I disassembled my new Cimarron Frontier today for cleaning and just to check it over.  FWIW, I've had it out to shoot just once, 100 uneventful rounds.  I noticed the hammer roller simply will not roll more than perhaps 1/8 or 1/16th of a turn, when it'll budge at all.  I see it's supposed to spin on a tiny little pin, but I'm not sure if there's a proper way to address the problem, or whether it's really a problem at all.  I'm sure it's not a good thing, but is it apt to become a big problem eventually?

If the roller is left stuck it will eventually develop a flat-spot where it grinds against the mainspring.  This will cause the cocking of the hammer to feel heavier, and might cause misfires as the hammer-fall is slowed down...
You can dodge the problem for a while by applying oil or grease to the contact points.

The permanent fix would be to contact Cimarron for a warranty repair.

If they won't repair it I'd suggest contacting a local gunsmith / gunshop if you don't feel you can fix it yourself.
My guess is that there is a burr in the mortise where the roller rides, or the pin has been bent during installation.

I would suggest you first grip the "roller" with Needle Nose pliers and start working it around, then drive out the pin and see what is what in its slot.  Or, if it's new, call Cimarron for Warranty.  Long term, it's bad JuJu.
