Traditions imports Pietta guns, so you were actually comparing Uberti with Pietta. The stamping you observed was likely the Italian proof house marks: one is the letters PN under a five pointed star inside a garland, and the other is a coat of arms shield under that same star/garland logo. Those marks will ususally appear on the frame, the barrel and the cylinder.
The frame should also have a stamp with two capital letters inside a square - that's the date stamp which decodes to the year the gun was made.
Pietta's manufacturer's stamp is the capital letters FAP inside a diamond, or the letters F.ILLI PIETTA. Uberti uses a capital U inside an octagonal muzzle shape. The location of these manufacturer's marks varies, but they can often be found under the loading lever on the bottom of the barrel, and sometimes on the frame in front of the trigger guard.
The feel of the action you describe is more a function of the individual gun than it is the design. The designs of the actions are almost identical between the Colts and the Remingtons of that era, with the biggest difference being the hammer mainspring. The Italian clones can vary considerably from gun to gun within either manufacturer's products depending on small details involving gthe finish of action parts. Most will benefit from being used, that is, working the action over and over (do NOT dry fire them, however, as that will damage the nipples). Once you are familiar with them they can be improved by stoning the mating surfaces of the action parts to remove burrs and rough spots.
Which brings up a point: if you don't already have some it's a good time to invest in a good set of gunsmith's screwdrivers. The Italian clones, and I mean all of them, are not famous for having good, hard screw heads, and if you use a garden variety hardware store screwdriver to disassemble them you will, without any doubt, at some time, screw them up. They are just too soft to put up with an ill fitting screwdriver. And you may even mar the finish near the screws when the screwdriver slips out of the slot. It's a good $30 to protect your $200 gun.
