I have both Marlin and Rossi's in 357 & 44 Mag. Should say "had" as I did sell my Marlin 1894C after a bit of experience with the Rossi. My JB Marlin 357 Mag loaded a cartridge like digging a hole in gravel now matter how much attention I gave it.
I own all the Rossi 92s except the 44-40 Win, from 357 Mag through 480 Ruger. All of the Braztech manufacture, the latest, and I've had no problems with them. My experience would tell you to remove the buttstock from the rifle when you get it and flush it with non-chlorinated brake cleaner until it runs clear. Then spray it down with a good gun oil and work the action 100 times (happens quick). Flush it again and reoil the clockworks. Do this a total of five times, 500 times, and your action will be very slick. Do this before you do any of the Youtube mods or buy any Rossi slicking kits. These rifles are packed tight with grease for their trip north and every bit of it needs to be cleaned out, or you will have problems. I did end up using the Gunslinger spring kit on all my rifles as I like the extremely light trigger. All mine are hunting rifles, not race guns, but I prefer the light trigger. These rifles are also configured as scout rifles.
My 44 Mag Marlin is a 1894P, a 16" ported barrel "Outfitter" modeled after the 444 Marlin of the same name. It is an outstanding rifle and wears the XS Sight System's scout base and Ghost Ring.
Back to the Rossi 357 Mag, I use it with a 190-grain 35 Rem cast bullet of my design, using 38 Spl brass to accommodate the cartridge overall length, long bullet nose, and crimp groove. I do load it to 357 Mag pressures. It drops deer and hogs like a heavy sack of taters.
I found the Marlin 357 Mag very critical of bullet nose and OAL. The Rossi is pretty easy going.
The metalwork on the Rossi's is very good with deep bluing. The wood on my 2010 through 2013 manufactured rifles used a waterbased, unsealed stain. The good news was that it was easy to remove and put an oil finish on them. The wood is "rubberwood." Seriously, and it typically has some interesting grain to it, but there is no effort on their part to match the grain to the stock set.
As a note, I carry a Rossi 351 38 Spl, and it is an outstanding pistol.
Rossi inventory levels really drop at this time of year as they are brought north in shipping containers. If you are not in a rush, wait. 2017, was a low inventory year as the plant that made them was being relocated.
