Accuracy with open sights is going to be effected by barrel length. I never got my hands on a 63, but I do have a Taurus 94 that I bought when the 63 wasn't being made and used ones were golden. Reason that I mention that is because my 94 has a 5" barrel and it shoots right in there with my MKIII Hunter - which is to say, very accurate. I see no reason why the same wouldn't be the case with a similar 63. If I was looking for a 63, I would try to find one of the 5" versions they made for a year or so. The extra barrel length isn't a bother on a kit gun, and should make the J frame shoot like a bigger gun.
