I own both
The 5 year old Uberti London edition is prettiest, has the BEST action of any revolver I own and also broke it;s cylinder hand in about 450 shots!
My other guns are Piettias and one CVA9 JUNK!)
The Piettias are wonderfull pieces of work, the cycle and are fitted very well and are very stronglly built!
Uberti is a good gun Co.
Piettia is trying hard and succeeding at building a good reputqtion for quality! CVA ire wallhangers.
