Uberti makes nice clones, although the color case hardening is seldom up to Colt standards.
Uberti guns are imported by Cimarron Arms, Navy Arms, Dixie Gun Works, and by Uberti under their own name.
Uberti will "flex" the quality of finish according to what price point the importer wants to sell at.
You have to compare the two quality levels side by side to detect the slight differences.
As example. Cimarron sells the top of the line versions, Dixie usually sells the slightly lesser versions.
Companies like Early Modern Firearms (EMF) sell guns by another Italian maker, but these are not up to Uberti standards.
USFA Unites States Fire Arms makes nice replicas, but their top of the line models are near Colt in price. They do make lesser finished versions.
