First look one immediately can tell these cuts are obviously not uniform. This is not an illusion due to photo angles this is actually an accurate representation of how sloppy these slots are. Is this a bad attempt at hand work or a CNC machine computer gone berserk ? I don't know but it's an astonishing curiosity to me. Sizes and shapes are all over the place.
Midway is selling Pietta fully fluted (not half fluted) spare cylinders for the Remington New Model Army ("1858" patent cylinder only) for $119.99.

Uh oh you might want to pass on these. The cylinder locking notches are improperly milled in both length (grossly so) and width on a sample I know of. So much so that you can clearly see it with your eyes. Not being too picky about perfect looks it was tried anyway.
Two of the chambers will not lock at all and the cylinder will throw by every time.
Another brand new Pietta locking latch outside of a firearm was tried and sure enough it fit in 4 of the cylinder locking notches but would not bottom out in 2 of them.
When installed there is throw-by every single time on 2 of the 6 chambers. That is unfortunately the obvious problem from the evidence presented.
I don't know if this belongs in the rejected parts bin or if it's the norm for certain sellers. In light of what is seen so far, I do not think this thing is safe to use. I am surprised a CNC machined product presents with defects this gross and am sure this must not have been properly inspected if it was at all.
I hope this is not the new expectations for Pietta quality since up till now everything I have seen or heard of their quality has been exceptional.
Standard Pietta drop in cylinders in the past (Same replica revolver) have been excellent and dropped right in. All of the above pertains to current manufactured products (CNC machined.) Nothing here is vintage.
Cylinder locking notches in my view are nothing to be messed around with unless one has gun smith skills and proper precision machinery. With tiny small scratches in the blueing in front of each notch from the locking latch partially dragging (a normal for Italian imports and considered within spec) I don't know if they will make this right or cry fowl.
Either way this thing was certainly never safe to be sold and should not be resold. Even with the bluing perfectly intact it's not safe.
I may share the response to the email sent when it arrives.
