I think .44 makes your search a little harder , rather than .45 .
i would really try and find a 2005 or later production .
Seems a LITTLE high @ 1900 for a 1979 model .
if your post count (15min.) allows , I would post a want to buy , and find one here .
i am confident you will find a fine example at a fair price from our membership.
Most importantly though - Buffalo Bore is usually a very hot load , make sure it is safe in your revolver .
