The only thing I might say, concerning newer Ruger SA revolvers, and I've had my hands on a bunch of them...Do a hands-on inspection. Although all of mine function as intended, some are definitely better than others. Some, the action is noticeably smoother than others, and some have cosmetic fit-issues with the grips and grip frame. If you've got multiples to choose from, look at them all, and pick the best one.
Another issue is front sight alignment. There have been some SA revolvers with the front sight canted to one side or the other. With an adjustable rear sight, the front sight misalignment can be nullified, but I don't like having a rear sight that has to be adjusted all the way to one side or the other.
In spite of the reports of grotesque QC issues, I guess I've been fortunate, as in a nutshell, I continue to be pleased with the New Model Blackhawks.
