Larry,
My response was directed to your comment about opening your arm on the rear sight not any other wear and tear. I also based that answer from experience with several Blackhawks one with a stock rear sight and the other with a Bowen, as I just got this flattop it does not have many miles on it at this point but no issues so far. I need to take another look at how the revolver is positioned in the holster where the leather meets the frame.

Your rig sounds like a good solution.
