After removing the grips and trigger guard, I found that the screw holding the spring and plunger in the loading gate assembly was almost completely backed out on both revolvers. And the screws holding the back strap in are covered by the grips on the Bisleys, so I didn't even look at them before, All four (both guns) were backed out. I tightened down all of the screws, and the two revolvers were like brand new. I need to find my purple lock-tite bottle and screw them in again. Thanks, gents!
