Perhaps, I really don't understand. Really. For the better part of 25 years I built Competition CAS rifles. Predominately Toggle Link rifles, a bunch of 92s, another bunch of Marlins. Predominantly though, Toggle Link rifles. About 50/50 carbines and short rifles with a few 24inch sporting thrown in for good measure.
Uberti built carbines, both '66s and '73s have 19inch barrels. Nobody cared. 19inches was just fine. The guns held plenty of cartridges, Built up very competitive, light and quick handling. Nice guns. Lots of after-market goodies.
Now comes Miroku. 20inch carbine and whoa, everybody thinks it's the greatest thing since canned peaches. Why?? that inch of barrel doesn't/won't make a bit of difference in the number of cartridges held, won't swing any better/worse but it really can't be built up to be considered competitive for CAS. Nice guns. No real after/market goodies.
Both guns are reproductions. The Miroku flavor is actually a copy of the Uberti. The Uberti is a Uberti. Neither is a copy of the Original Sample Example except in external appearance. So when we come back to the front sight, stuck on the barrel or part of the band, I have to agree with Yahoody. Not better, not worse. Just a different way to get to the same end. Of course, I also have to place a CAVEAT into the mix. I'm not a champion of the Miroku. Too many things about it I don't like. Oh well.
