Do you think that the barrel in your Bauer is stainless also? I think mine just HAS to be. Also, I got an e-mail from a parts company which said that all Baby Browning parts will fit the Bauer. Taking the three apart, everything looks exactly the same. Plus, there just aren't that many parts. I checked for the "looseness" you mentioned and all three have a little. Seems to be a normal thing. I believe you're right on your fouling theory.
