That 44-40 barrel adds considerable value to the '92. Unless it's a POS.
This.
Also the M92 conversions to .357 usually start with a M92 in .23-30 or 32.20.
A .44-40 is not suitable for conversion to the smaller cartridge.
These conversions were popular years ago but now are not practical for a number of reasons. Trust me on this, I spent a few hours researching this after buying a converted Winchester 1892 in .357. Mine works well with medium level cast bullet loads but I would have been better off with a modern lever .357 ....
