Not correct. They are made by Miroku in Japan, quality is outstanding as with all Miroku-made guns. The other points regarding the M1892 being a much more stout design are correct.
I'm trying to figure out where that came from, considering the rest of the thread?
Uberti is still making 73 rifles, and have been for a long time. Miroku is a relative new-comer compared to the Italian clones.
I would be willing to bet, you are correct, the japan rifles are undoubtedly stronger. They make some nice rifles.
The issue with the 73 isn't who's making them, but the limitations of the original design.
But it still remains one of my favorites.
