Part of why 73s feel slick is the way the action functions, as well as the fact that the carrier(lifter) raises the cartridge mostly horizontal, rather than angled and have to make it around the corner of the chamber so to speak.
In terms of parts availability the Uberti guns probably have it over the Miroku guns, though to me I wanted the Miroku for the perceived quality (all the Miroku guns Ive had or seen are very well made) as well as the name Winchester on the gun. Ubertis are pretty good, and better over time, but have had some quirks, like gunsmiths saying theyve seen some that the barrels didnt torque or index quite right and the factory loc-tited them in place rather than change the barrel or set it back a thread and re-fit the mag tube and fore end. Its been a while since that was reported, and I think theyve upped their game since. ubertis also have a reputation for soft screws, in Colt type pistols and I believe in rifles, to the point theres replacement screw sets available. As far as needing parts, im not sure either really need parts in general, though its nice to have access to spares if one loses or damages something. I havent inquired from Winchester about 73 parts so far.
The loading gate/spring cover/whatever one wishes to call them, have had some issues with Ubertis I believe, the cartridge stop on the back of them have broken, it seems to be a known thing if looking on the CAS City forum site. I dont know if the Miroku guns suffer from the same malady, (I recall asking about it some time ago but dont recall the details) though it occurred to me i may want to get a spare or two. I like keeping basic parts that are easily lost or damaged. Most of the originals seem to have held up well, I dont recall what was changed on the copies that caused the problem. Theres some nit picking by some people about 'theyre more like the originals in some minor detail". None of which details that were mentioned in those discussions were things I care about....although I much prefer the Miroku carbine front sight, a stud brazed onto the barrel with a blade pinned into it, the Uberti carbines have the front sight made as part of the front band. I had a Uberti 1866 so made, it was a huge pain in the arse if it got dropped or bumped, you had to then re-zero it. I dislike that type front sight greatly. Doesnt seem to bother other people.
I wonder if the magazine spring in the Uberti 73s is the same as the 92s, I have no experience or information about that detail. In the Miroku 73 I have the spring is very soft and many coils, I believe its intended to be so to reduce spring pressure and the cartridge slapping back into the stop when the carrier comes down. It also makes the magazine super easy to load, none of the business of not loading a round all the way in so the next one can start easily. The 73s and 86 load slick as can be without such methods. the 92s and 94s nearly as slick when the back of the gate is polished well and other internals arent too rough. Ive done trick of not pushing each round all the way in in the past with Winchester 94s and thought I was clever, then several times had a handful of shells spit back out the gate. When they work correctly none of that is needed or desirable. Winchester used to suggest it, but I believe they were covering their tail when making roughly finished guns and got complaints on them being hard to load. Blame it on the user, not the gun. Theres a simple fix for 94s that are hard to start cartridges in.
