Actually it is not a coating it is color case hardening. Yours is not one of Piettas better examples not effect on function but does detract in looks shouldn't have made it past quality control.
How does it shoot?I just bought this Pietta 1851 Navy & I'm not happy with the loading lever. The hinge area coating is pretty bare. Is this normal for Pietta? My Ubertis look much better.
And your source for that is what? You might want to watch some of the youtube videos of production at the Uberti factory. The Italians use cyanide case hardening and used to use a rolling quench that produced the lighter streaky colors you used to see. They have changed quench aeration and the colors are now pretty good. Not up to Turnbull standards but not bad.None of the standard guns being mass produced these days are using case hardening. It is just pretty colored dye, fellers. They offer "case coloring", not "case hardening".
With all due respect you have no idea what you are talking about.It is easy enough to test whether the gun is truly case hardened or not. True case hardening cannot be cut with a file. Try running a file along your new Italian repro revolver in an inconspicuous place, such as the underside of the receiver after the trigger guard is removed. You will find a file cuts it with little effort.
The old guns were made of wrought iron and were case hardened. The new repros are made of modern steel, and do not need to be case hardened. Modern guns are heat treated, but not actually color case hardened, unless done purely for aesthetics (such as what Turnbull will do). Case colors (dyes) can be added over modern steel for the traditional look of color case hardening, but are only decorative.
If you're gonna shoot it, it will "cook" over time on it's own, and look like a, well, nice used piece!I just bought this Pietta 1851 Navy & I'm not happy with the loading lever. The hinge area coating is pretty bare. Is this normal for Pietta? My Ubertis look much better.
I hope you do not work on other people's guns!Color case hardening today is a chemical process easily fixed with some Birchwood Casey’s Super Blue. Just clean with alcohol and swab with a Q-tip in a pattern you like. Then lightly use some steel wool and oil it. Good as new.
