I did see a guy buy a new MK Ruger and it did lead up quickly.
He sent it back and they replaced the barrel.
So maybe the Single Six story is based off somebody having gotten a bad one?
I've had two .22 mags and both were fine.
Fam has owned a half dozen convertibles........no probs (old and new models).
Having shot a few, I'm more interested in the adj sighted Bearcat.
That thing is just too cute (and would be perfect on a trap line).
