The disappointing thing with genuine Winchester lever action rifles is that they chose the 1894 (because that is all they made at the time in the 1970s and subsequent to them) for the basis of a pistol calibre cartridge rifle rather than the 1892 that was designed from the outset for pistol calibre cartridges. The 1894 was designed for rifle length cartridges as isn't and wasn't the best choice for .357 Magnum or .44 Magnum cartridges.
Regarding reliability issues I spent a memorable three to four hours welding back up and then slowly fitting and adjusting the worn magazine cartridge tube stop on a .44 Magnum made in the 1970s Winchester 1894. Put it together. Does it work. Make a stroke with the file, put it together, and repeat and repeat. A stroke at a time as one stroke too many and you had to start all over again. They were a PITA to work on if parts had worn for, as 8x57 rightly says, by the late 2000s spares were non-existent and one had to repair and mend.
