I bought a used Cimarron Thunderer some time ago. In attempting to find the date of manufacture, I learned that Cimarron has a custom shop. All of their serial number data is only held for five years and I was told that the custom guns are not marked which seems odd. Anyway, the action is tight and slicker than snot. The average of three trigger pull measurements is 1lb 14oz. I have a Schofield inbound and was thinking about selling this Thunderer, but I may keep it. It's been in the safe for a couple of years and I've not fired it.
