Uberti, and Pietta have been hit by the corona (China) virus real hard. Their has not been enough manufacturing to keep up with the regular supply chain, let alone the high demand, and the covid factor.
You know its bad cause Pietta owns EMF, and they only have some brass framed 51s in stock, as of the other day.
It will come back with new stock as soon a they can get back to full manufacturing.
