Back to Ubertis:
No single action that lacks a transfer bar should be carried six-up. We have one individual on these forums who insists loud and long that this critical safety practice isn't necessary.
If I was a moderator I would have tossed him out about the second time he made this claim, after warning him the first time.
As to Uberti quality: both Uberti and Pietta updated their factories in the 2000-2001 era. The guns produced after that are generally pretty good. The two semi-consistent complaints I've heard concern oversize chambers, esp. in 45LC but others as well. Throats are sometimes oversize as well. This doesn't do good things for accuracy and it can also shorten the life of brass used in reloading, a necessity for most folks with some of these calibers (such as the 45LC!).
I believe current production Rugers are better guns, esp. the mid-frames from 2004 forward and the large-frames from 2007 forward. The latter can be IDed with the barrel "lawyer's warning label" - if it's under-barrel on the large-frames it's the right newer type. Chambers on these guns tend to be uniform, smooth and tight exactly as you want. The only possible gotcha (and again, for some reason mostly in 45LC) is that the throats will tend to be tight but $40 and a trip to cylindersmith.com fixes that. The Ruger action parts are tough as nails even on the mid-frames - the pawl, hammer, cylinder bolt, springs, trigger and other internal bits are all the spec (and usually swappable!) as the larger-frame 44Magnum-class parts. My mid-frame New Vaquero in 357 is wearing a SuperBlackhawk hammer and has since I installed it in 2005 with no problems at all.
Now. That said, if you want a traditional type action instead of a Ruger, the best Uberti you can get is one made to the "El Patron" finish level and then tuned by a respectable stateside gunsmith. And there's two easy ways to get that: Cimarron sells the "Evil Roy" which is an El Patron variant that they tune up stateside, and Longhunter Shooting Supply is a gunsmith and gun dealer who buys Taylor's Smokewagons and Running Irons (both Ubertis at the El Patron finish level) and tunes them up before shipping them out:

He's also now selling some other slightly lesser Ubertis that ship under the Cimmaron brand name if you want to save some money or want the Thunderer-type grip frame, and he pre-tunes Rugers as well. I assume he'd tune up one of the Cimmarons if asked - his prices on those are for guns as Cimarron ships them I think? He doesn't sell the Evil Roy but I believe his pre-tuned Taylor's are going to be very similar to a Roy and a better value overall.
I would also guess he can get most anything else in the Ruger lineup and pre-tune that, esp. if it's an SA
. He mostly caters to the SASS crowd so there's no listings for Blackhawks and the like. Buying guns pre-tuned by him means not only is the gun improved but he sends any real "birth defect cases" back to Ruger before you ever see them, and esp. considering there's no extra shipping costs he's one of the best deals in gunsmithing available.
