Stanwel there were Brownings and brownings.
I spent 3 days checking and servicing the general issue ones.
They were in awful order working parts slack just in tolerances when drifting the barrels.
Now these were the ones people signed out and weren't allocated to individuals.
The individual personal weapons. Those a thick idiot like me never got near they were signed over personally to the staff sgt and only he worked on them. If they were even slightly out they had new parts and those parts would then go into the general issue ones when they eventually failed.
To keep them sweet you apparently needs to fire them at least every 3-4 weeks. For those left in the Staffys care he did this for them until they could reclaim them. It was something to do with the gun metal sweating. I am sure nutloose knows more about it than I do. I was just the dicked help when the stupid old fart managed to belt his thumb in the door of the machie wagon.
I suspect those that most of us shot were the general issue things which have an extremely hard life with nobody really looking after them.
