I just bought a new Pietta 1860 Army, here is what happened after about 100 rounds. The first thing that I noticed was the bolt head hitting on the edge of the cylinder notch and knocking it in. I had to shorten the leg on the bolt to make it hit earlier so it would be off the edge of the notch. I think this is common with all makes. The next thing I noticed was the bolt is really denting the cylinder, I guess the spring is a little strong, or they just use soft metal.
I did find alot of burrs on the inside parts that had to be removed, and the trigger pull had alot of creep. After some polishing it did smooth up.
The bad thing was the gap between the barrel and cylinder opened up to .011, it was not that loose out of the box. It took some work with a file, and fitting a new wedge after the file work was done to close the gap back up.
The grips had a dark finish on them, so I had to refinish them to lighten them up some.
The screw in the loading lever could not be tight or it would almost lock the lever up and not let it work. So it took some work to loosen it up.
It does shoot good and groups well, but that is alot of work for a new pistol. I have one Uberti 1858 in Stainless Steel, no problems with it. I have two 2nd gen. and one 3rd gen. Colts, no problems there.
Would I buy another Pietta, no way. I would put my money on a Colt if I could spend the extra, if not, buy the Uberti. I know my comparison of my Pietta and my Uberti is probally not a fair one, because my Uberti is Stainless, but that is the only one I have. I did not have to remove any burrs inside of the Colts or the Uberti. No problems with them.
I heard talk that Pietta has improved their Quality in the last couple of years, this one is dated 2007, they need to do alot more. Sorry Pietta fans if I've pi*#ed you off, that is not my intention, just reporting what I found so this guy can make the right decision.
