It depends? Is it new in box, unfired with all the papers and hang tags? Was it made in the USA or in Canada? As above, USA, one of the websites I looked at said (IIRC) $950, if Canadian made, NIB, unfired $1200 according to the same website. I don't know where they get their info and I don't know how old their information is.
I bought one this last weekend (March 2011) in beautiful looking shape, possibly fired, maybe not. No box or sleeve and no paperwork, in other words it is "a good shooter", for $400 from a dealer. I don't know if it is made in USA or Canada.
