Well bigbulls sometimes you get a good one and sometimes you don't . i just have seen some buckmarks that had problems. this wasnt the first.
It's kind of like the rem. 742 debate i happened to get a good one and others didnt.

When i worked for a friend in his pawn shop we had several returned for jamming. yeah browning fixed them but i can't recall any rugers having problems. but thats not to say they haven't.
