Glad to see that the gorilla didnt tighten the screws on this 2016 revolver. Nother pleasant surprise is the arbor length ... It is rite on for a tight wedge and a gap of .004 so far. May loosen up with firing but for now very pleased.
bigted: The gorilla works for Pietta. I don't know if he moonlights for Uberti.
Pay attention to the two guys quoted below. They both have their sheet together and know a lot!
Hey bigted!!
If they're Uberti's, they got short arbors!! Don't sight um in till ya fix that!
Just sayin' . . .

I thought my dragoon had a perfect arbor because I could remove the cylinder and put the barrel on with it turned a little and it matched up to the frame perfectly. Put it back on correctly tho and drive the wedge in a little tighter and it locked the cylinder up. It took two flat washers and very little filing to get it right.
For clarification, the washers that Hawg refers to are added to the end of the arbor so the arbor bottoms out.
Just because you can fit the barrel on the arbor off-center and the barrel lug mates to the frame with no gap only proves that the arbor is not too long, which is hardly a concern with either Ubertis or Piettas.
If the arbor is the correct length and bottoms out in the barrel lug recess, it won't loosen up after firing and will always maintain the same barrel/cylinder gap. The purpose of the wedge is just to hold the barrel tight to the frame, whether it is just a firm thumb press or tapped in tight with a small mallet. It is not there to adjust barrel/cylinder gap. If you think so, you have a short arbor.
IMO, the only exception to this is if you have a brass frame and shoot heavy loads. This can cause the cylinder to back into the recoil shield area which can cause the barrel/cylinder gap to increase, among other problems.
Listen to these guys! They have been around the block more than a few times.
