I've handled about half a dozen Piettas.
The first one broke in my hands, after the salesman handled it exactly as I did.
"Wait, what? What? Did it really just do that? I guess we'll have to send that back."
The second one broke in my hands, after the salesman handled it exactly as I did.
"You're supposed to open the loading gate." 'I tried. Now everything is jammed.' "Huh. It is. We'll send that one back."
And on goes the saga.
Another came to me after several years of not being cleaned, because the owner could not get it apart. I took some special liberties in pounding the wedge out, before making a special brass punch for the owner to use. That revolver needed a special tool for disassembly.
And on the story goes.

I own one Pietta. I don't recall the model, but it is a (anachronistic) .44 cal black powder revolver that blends aspects of the 1851 Navy and 1860 Army.
After lubing the nipples and proceeding with the first firing, my nipple wrench bent and was completely ruined when attempting nipple removal for cleaning.
Long story short, I had to buy a high quality wrench and new nipples.
Not a fan. But after upgrades, it works.

I see Pietta revolvers like I see Heritage revolvers:
Good enough if they work, but they usually don't.
