So, let me ask this question, if a clone and a 3rd gen both need work sometimes out of the box and eventually, will need rebuilding from extensive use in say CAS matches, then is the Colt really worth $700-800 more....are you really buying that much more gun for the money? To me it doesn't sound like it from a practical standpoint or an economic one if the gun is to be used as intended or pushed to the limit in CAS matches.
yes, you are buying more gun, specially if you are a target shooter or collector.
In the COLT, The finish is much better, the case hardening is spectacular,
and the rifling is different also in the COLT, anticlockwise and very well thought for lead bullets, as the ones allowed in Historical weapons matches, far more adqueate than the Uberti´s, more thought for jacketed or very tough bullets, and that will get leaded much easier in my experience.
I had more troubles with UBERTI getting accurate loads than with COLTs or even Gauchos, a wonderful no longe made revolver.
In general, at least the old ones, have a problem: chambers are too big, not exactly rounded, and with size differences, and the bore, too small, 11,43 mm or 450", while COLTS have perfectly bored chambers of the right diameter and the bore is 11,45 mm. The Ubertis tend to developed more cracked cases, something not as common in COLTS. You can correct that by sizing only the neck..but I dont do it. Not sure if really improves accuracy.
in general small parts seem to be more durable in the Colt in my experience. Cocking the hammer is not soft as some Uberti or Pietta clones because of a stiff spring, very adequate for accuracy, with a fast hammer fall.
with Uberti, it took me a long time of experimenting to get these loads, for competition at 25 meters, including some failures like the load below. this revolver is just not accurate with most loads
trying and trying....with different bullets, different fillings...and same load...
until I got what I wanted, a load that this italian revolver really likes
..6 shots, one flier, and 4 shots in the center of the O ring, another one very close....one hand held at 25 meters, with 26 grains of 2F black Powder.
all the best
