I have both Uberti and Pietta Remingtons, and like them both, although the Piettas were older models than needed more tuning and corrections to get right, and folks have said the new Piettas are significantly improved.
As for size, I have Kirst conversion cylinders for two 36s and two 44s. They timeshare the backplates, and though dangerous, the 44 cylinder will fit and function in the 36 revolver, so I must switch with care.
