I've always "jumped", thinking I would figure it out later.
So far so good.......
One day I was looking for something else at a local gun shop (LGS) and spotted
a long, blued barrel with a small hole in the end, which drew my attention right away.
When I looked at it closer I snagged it, no matter that they wouldn't budge on the price,
saying it was too soon for that to happen since they had just put it in the case.
It was an all original, "one liner", K22 with 6" bbl in excellent condition.
Another one I picked up like that, at the same LGS,
was a nice M649-3 with forged hammer & trigger, box & papers.
It mattered not that I was lookin' for something else at the time.
