Boge,
     I purchased a Starr SA made by Pietta several months ago from Cabelas in Owatonna MN.  I have only fired it on one occasion, thus far.  I had trouble with cocking the hammer on it.  I don't know if it is characteristic of the piece or it just needs to be "worn in".  I have cocked it  repeatedly in front of the tv,and it seems to be getting better.  I 've read that they need to be cocked briskly,since.  The front sight was too thin for my liking,so I have replaced it with a thicker,taller one from "Track of the Wolf". the rear sight is a very thin shallow notch on the hammer, which I have opened up with my Dremel tool to allow me to at least see the sights.  As I recall, it was shooting high, but centered.
    This revolver points well and is a joy to shoot, barring the sticky hammer problem.  It does not have a cylinder pin that goes clear thru the cylinder, so fouling was not an issue with it,asI merely put a little Ballistol on the front and rear of the cylinder.  The large thumbscrew on the rear of the frame is a very handy dismounting feature also.  I'm looking forward to shooting it some more in the spring when I get healed up from carpal tunnel syndrome surgery.  Hope this helped.
