My Father passed away and I received his 1911. It had been under his pillow for at least 10 years I know of. How many more I can't guess.
(Side note: He was a DS in Cook County during Prohibition and always had a loaded pistol around him after that. He didn't carry. He told me no stories of his duty.)
Since he had the same chambered round all that time, when I got it I had to use a dowel and press the round out back through the chamber. The brass had corroded in the chamber in that time.
The magazine seemed fine.
At least re-oil the gun and cycle a new round through it once in a while.
