I WISH ours were so well treated.
We had instructions to fasten ours on tight, for a while a hose clamp was the medicine. Problem is, ours had to have a flexibility during use and without it they would break at the front of the locking spring at the bottom front. They wouldn't come off but extend forward and be useless. People just wouldn't accept that things that look good aren't always serviceable.
This usually happened when transition range was present, transition from blank to live. Then senior men would have to get their head on straight and keep supervision to a one man checking everything equally. Otherwise a weapon would be overlooked as everyone else thought someone else had checked and it would burst a muzzle from ball contacting a blank. I still can see a FH that was destroyed during a night attack. The man that had the accident was trying to remedy the failure to function and was firing singles at that point...
