Now find an extra magazine for it.
Great rifles, with a really junk magazine.
I hear that a lot, yet my 1967 581 ran fine for decades with its only one. It eventually started to balk a bit, so I when I bumped into a new one in my LGS, I bought it, $10 IIRC. I think the old one is probably gummed up with bullet lube from the thousands of rounds it's fed.
