yes, they have changed several things. at first i got the impression that they were after a novelty type item with the 45/70 etc. then they came out with other calibers and tried to enter the "normal" big bore market and not go after novelty type shooting. i'm calling the .45/70 a novelty item b/c they're the only one to make one, not cuz it's not a great gun. however, they've changed the source for many parts most importantly the cylinders, they've improved and changed the shape of the grip frame, and based on the examples i handled in 2001 or so, definitely improved the fit and finish on the guns. much tighter, better triggers on average. just a very nice all around improvement. just goes to show, if you put out an average or crappy product, it will take a while before people take notice when you improve the quality. the ones i handled before weren't on par with rugers imho, but they are better than rugers now imho. i first took notice when john taffin tested the .475 and got some insane accuracy. i contacted him to see what the deal was and he told me that gun was as accurate as any he'd shot, including his FA. the ones i handled weren't as tight as FA, but they were not any less accurate in my hands shooting off hand, whereas, my cousins' that have had a couple blackhawk .44's were noticeably less accurate. one day i'll have one in .475 but i've got plenty of .454's and that's quite enough gun for anything.
