I am the original owner, bought it new. Ruger made a special run of these a year ago and had them case colored by Bobby Tyler (oven baked) in Texas. They were a Talo special order. They made 500 of them.
I have two .44 carbines and three Deerfield .44 carbines. The former are quite ammo sensitive. I think they were set up using Remington 240 gr. rounds. I love them all!
This same situation occurred with the Mark IV pistols when they were first released, resulting in a nationwide recall. I had the recall fix done on mine.
I think a couple of people have recently posted that their bought-from-Ruger pistols had canted front sights. Ruger fixed them free. I'm guessing they will do yours too...unless it is not an original barrel.
