Slugflinger: Damn I hate "scratches in the finish" of any of my many guns!
Sadly the situation you describe, I have seen happen, on rare occasions before!
Most notable was the following incident!
I was a police officer at a large west coast municipal department. At roll call one evening the Captain and the Lieutenant were conducting a formal inspection of "the troops" and I was an "acting Sergeant so was at attention off to the side of the three ranks of officers.
The Captain choose to inspect one of the elder officers sidearm! It was a Smith & Wesson Model 10 and upon handing the revolver over to the Captain the pistols cylinder release latch and screw fell to the floor!
An awkward silence ensued as to "who" was gonna retrieve the Smith & Wesson parts from the floor - the beat officer in question finally retrieved said parts and a "talkin to" ensued!
I think, that over time, "recoil" can loosen the parts in question.
Lesson learned and reminded.
Thanks for sharing.
Hold into the wind
