I have and use a 3 1/2" Uberti "New Thunderer" (I think that's what they were calling it when it first came out several years back) in .45 Colt, with checkered Walnut grips. Got it primarily for cowboy action shooting. Needed a bit of a tune up; the barrel needed a slight twist to get on target, and since the cylinder was not as tight as I would have liked I replaced the cylinder pin with a Belt Mountain number. It took about 2 or 3 hours carefully honing the pin with a felt bob on a Dremel Tool, but once in, it helped a lot.
I ended up not using the gun for cowboy action shooting, primarily because of the short barrel. I do use it once and a while hiking here around home in western Colorado. Carry it in a custom El Paso Saddlery Cross Draw. It is compact, and with handloads of 9 grains of Universal behind 255 gr. Silvercast SWC I can do about 2-3 inches freehand at 15 yards.
It is not my favorite poking around the mountains and canyons piece however. I have tumbled into a stream in the wilderness area near Independence Pass once, soaking everything, me, my wife, our fannypacks, pistola and so on. It actually turned out kinda fun since my wife and I dried out bare naked on a nice, warm, out-of sight boulder. But that strengthened my fondness for stainless steel. Also the proper "Cowboy Way" of carrying means five beans in the wheel, as the say, if you carry the Uberti with the hammer down on a empty chamber. Depending on elevation, morning dew and condensation can happen about any day of the year.
Now I more often turn to my Ruger Bisley 5 1/2" 45 Colt in stainless in a custom half-flap cross-draw. It has had some custom work as well. A little more weight, not as compact, 6 rounds of 300 grain Hornaday XTP at about 1,100 fps and more accurate than the fun Uberti.
