My Stainless Bulldog Pub has been back to the factory 3 times for repairs.
Fortunately all were covered by the lifetime warranty.
All three problems could have been prevented by better quality control during
manufacturing.
I have learned to shoot really light reloads in the gun. It can't handle even factory
loads for very long without needing repair.
Maybe you will get luck and get a better one than I did.
Good luck!
