Before trusting your neck to an out-of-the-box Uberti there are some things you should know. They are an excellent buy for the money, but they are made to sell at an attractive price point, so something has to give, and does.
There is a little cam on the lower/right side of the hammer which works the cylinder bolt (the part that locks the cylinder in line with the bore). In the Colt this cam is a separate part, and as hard as a banker's heart. In the Uberti and other Italian clones the cam is part of the investment cast hammer, and neither is particularly hard. Since the tail end of the bolt is hard it doesn't take the cam long to wear, after which the lockwork goes out of time.
In older production the hands (the part that revolves the cylinder) are like the original Colt, with a spring made from thin flat-spring stock. They are fragile and tend to break. Newer Uberti revolvers have a plunger and coil spring. Make sure to find out which you have.
The cylinder bolt and trigger are tensioned by a flat spring, and the side that puts upward pressure on the bolt tends to break off over time, and the cylinder bolt also has a reputation for having the tail break off. Either failure will leave you with a locked cylinder that won't move.
All this sounds very dire, but obviously everything doesn't happen at once. My point is that the original Colt design (which Uberti faithfully copied) did not have a reputation for ruggedness, and the Uberti doesn't either. It is more then acceptable for the various non-weapon purposes it is usually used for, but I would find one questionable for serious defensive use, especially for one in law enforcement that must face additional risks.
One of the larger customer bases that buy and use Uberti revolvers are competitors in the cowboy action shooting games, and most of them don't baby their guns which see frequent and hard use. Gunsmiths that serve them have learned of various ways to improve the reliability of these guns. I suggest that you get some second opinions by going to this link:
