I bought it used and the only thing the guy behind the counter, said when I asked him is that, it might have been a special run through a distributor, he was not sure, it was a big place with a lot of workers, they had just taken it in on trade the week before. I was looking for a used ruger 454 at the time and at first thought it was a 44 mag, but after looking closer I relized it was a 454. I liked the way it looked, so I got it. Is there any way to tell how old it is? Thanks for the replies.
