If there is one thing Ruger does well, and has a lot of practice at, it's issuing a recall. If it has happened it will be on their site, and if you sent in anything in the original box that looked like a registration or warranty card, they will mail you personally.

"Thank you Mr. Obvious"! I think some of them absorb the BS customers carry in through the door.
Thanks for the recall info, pudly. You may have prevented some of the above!
