I contacted Cimarron and they told me the loading gate screw is a known issue and sent me four oversized screws.
I think usually in cases like this those guns were built before the problem was identified so now the issue has to be fixed with replacement parts. It probably had already been fixed in new production guns. As for the gouged up gun, I wouldn't have accepted it from the dealer. Dealer should have ordered another gun and sent that one back to the distributor.
