Having fooled around with original Colt percussions (and replicas) off and on for about 50 years now, I have not found the new ones to be anywhere near the quality of the originals. I have had 1st and 2nd gen. Colts, Centennials, and currently have three Uberti percussions (a Walker, 3rd Model Dragoon, and a '61 Navy).
Original guns from that era are now around 150 years old, and finding one in nice shape with minimal honest wear isn't easy (or cheap). But about 30 years ago I lucked into a very, very nice 1860 Colt with a lot of blue, all the cylinder scene, was tight as a tick, and but for one minor spot in the bore, perfect. The difference between the fit and finish of that gun and replicas was like night and day. Naturally I sold it and all I got in return for it was filthy money. But it was a revelation.
I have had that same eye-opening experience with the internals of Shiloh Sharps versus originals. The Shilohs are indeed pretty and do work, but all you have to do is look at the inside of the lock and it's a whole different world. I once had occasion to disassemble a Spencer that had led a very sheltered life. The machining and vivid case colors of the very intricate breechblock were a sight to behold. It was literally a work of art.
Of my Ubertis my favorite was the '61 Navy; very pretty, very well balanced, and an excellent shooter. When the hand spring broke I had to take it down to fit a new hand and spring. Pretty rough in there, and parts durability is just too iffy for me. It's now on retired status and looks great in a fitted case. The Dragoon gets shot infrequently, and the Walker hasn't been shot at all. Their role in life is to look nice and impressive, and they do that very well. If Ubertis were made like that old original 1860 Colt with hand fitting parts of the best steels they would probably cost $1200 and up. Bear in mind, too, that the current Ubertis are probably the best of the import replicas these days.
I have had three Ruger Old Armies, and while they aren't a copy of anything, they are essentially Blackhawks--tough, reliable, and just go bang. They would have sold boxcar loads of them back in the 1860s!
