Let me suggest that you run no less than 200 rounds through your revolver, and THEN assess your level of satisfaction. I don't think all the articulating parts within a double action revolver can "wear in" and lose any burrs or rough spots on them in just 50 rounds. I suspect you'll be able to tell SOME difference after 200 rounds, and a bigger difference after 500. It needn't be all magnum-level loads, either. You might want to play around with different factory loads to see which seems to shoot best through the revolver. The loose transfer bar kinda concerns me, but if it doesn't cause a malfunction after 500 rounds, I'd bet that it never will.
I think it's also entirely likely that a great many parts made for a S&W revolver of similar frame size can also be used in the Taurus revolvers, probably with minimal fitting and polishing. If Taurus still offers a lifetime warranty, then it speaks volumes about their intention to obtain and keep new customers.
I've shot 3 different Beretta M92s, and 5 or 6 of the Taurus clones. All but one of the Taurus clones shot noticeably tighter and more reliably than the 3 Berettas, and the one that didn't shoot better shot groups so close to the size of the Beretta groups that the difference wasn't worth mentioning.
