As with all fixed sighted revolvers, you take a chance on if it shoots right or left. If you can't correct this yourself, it will cost you to have it corrected. I've had Uberti's that shot to point of aim, and some that didn't.
As far as reliablity, the Uberti's are better than they used to be I think. I was breaking hand springs in them many years ago, but they got better in some area's. They are using them for cowboy shoots, so that says a little bit, these people shoot the heck out of their guns. You can buy replacement springs from Wolf for pretty cheap that fit right in them too.
There are several places that import the Uberti revolvers, fit, finish, polishing, timing, ect....will vary.
I notice around here that the high end Uberti's, which have nicer fit and finish are approaching the USFA Rodeo models in price. If you get a Uberti like the "Evil Roy" model which is sighted in and tuned up, it surpasses the lower end USFA's in price, so you have lot to choose from in the way of Uberti's and prices.
I think (someone correct me if I'm wrong) that EMF, Cimmarron, Taylors, ect....area ll Uberti's, just different fit and finishes and price ranges...I think.
I like Uberti's myself, they are a lot of neat things to choose from, including open top conversions if your realling feeling nastalgic.
