Which is better - Uberti or Pietta?
Which is better - Sig or Kimber?
Which is better - Smith & Wesson Shield or Glock 43?
It's all in the "eyes of the beholder". ANY brand can have some problems once in a while - that's why most manufacturers have a "service department". If there weren't problems - they wouldn't need service departments. Neither would Ford, GM, Toyota . . .
I have had and do have both Piettas and Ubertis. I have no complaints with either. Both brands have good fit and finish, function well, shoot well - both C & B and cartridge wheel guns.
As far as Uberti's shaving deep cylinder pin holes - a properly fitted wedge should go in and be thumb tight - and should be able to be removed the same way. The problem is that too many people think it needs to be whammed in tight. As far as cylinder gap goes . . . it's all about "tuning" your cylinder pin, wedge, etc. to obtain the cylinder gap you want and keeping it that way by using your thumb on the wedge . . . not a mallet.
Forget about what others "think" . . . everyone has their own individual opinion. Just because you "read it on the net" . . doesn't make it etched in stone. If you are wavering . . . . go to where you can look at them in person and where you can make a selection based on what "you" think. I really don't think a person would be disappointed with either brand.
