Keep in mind that Cimmarron is an importer, and not a manufacturer, no matter what they may lead you to believe. They do import Uberti guns, and maybe Pietta or other Italian manufacturers.
Get the correct manual at:
www.uberti.com/manuals
and ID the spring number
check with:
www.vtigunparts.com
for a replacement spring.
Keep in mind that Uberti has changed parts shape and configuration from their older models of about 12 years ago (?) - at least their cap & ball guns vary considerably from old to new.
Current production models appear to use SAE threads on the screws instead of metric. When you contact VTI be sure to give them the proof date.

A replacement mainspring will likely be just as heavy as the one you have now.
Here's an example of an aftermarket mainspring designed to be lighter.

The Brownell's spring appears to be out of stock, but you can modify yours, as I did, to look like theirs by using a dremel tool to remove material from the center. I had a replacement spring on hand in case I messed the first one up, but the operation went fine.

Cimmeron Springs
I had the same problem with two Uberti Cimmerons Mod. P guns I use for cowboy action completion . I had a local gunsmith in my area "tune" them up who replaced the main springs and bolt and trigger springs. He also polished the actions. Did that ever make a difference in the way they shot and shortened the trigger time considerably . The accuracy was greatly improved with the lighter trigger spring and polished actions.
I also replaced the main springs in two Uberti 1875 Remington's with lighter springs too and that made a big difference in the way the guns cocked. I didn't replace the trigger and bolt springs because the trigger pull on both 1875's was about 3 pounds already. These 1875's are the most accurate cowboy action guns I have. They are heavy and a little more awkward to get into action than the Cimmerons but for distance shooting (40 to 50 yds.) I seldom miss a target . When I do miss it is my fault. I got the replacement springs from Brownells supply. Big Coulee

Cimarron has (or had) an on-site 'smith at Frederiksberg who provide tuned up guns - speak conditionally since the friend who had one done did it several years ago. The tune up involved everything polished internally, main-spring lightened, but not to degree ignition was unreliable (actually - when he got it, there were issues with ignition and back it went, with things fixed after about six or eight weeks). Dunno if they are still doing that. Gun was quite smooth and let-off was about 3.5 pounds and crisp.

If you work on a flat spring, be sure to grind/file/polish in a direction lengthwise to the spring; never crosswise.
