Do you have a checklist for Inspecting a gun during an inspection period?

[B. Dudley]

Check the ribs! Hang barrel on your finger and knock the tubes with your nuckle. Listen for a steady ring sound. Anything that sounds flat or like a dull thud is very suspect for loose ribs. Also look at the ribs joints very closely. Push down on the rib and look for movement at the joint. A little oil in the crack of the rib might help since it can be seen pushing out from a point if the rib is loose.

Other than that and others that you mention, if the gun is as described, tight, solid and fits you. Put it into your collection.
