A few years ago , I picked up a Rossi 92 16" in .357, it worked OK but needed smoothed up. A friend with a M92 in 45 said just shoot it and it will smooth up..
Not being one that will just let well enough alone..

I ordered a safety plug, magazine follower , & Rossi 92 video from Steve's Gunz. The video was a great help to smoothing up the 92 action, what needs to be done, what didn't , and a couple of tricky assembly problems. Well worth the price of the video.. I also refinished the wood & changed the sights.
A few months later a gentleman that I know purchased one in .357 with a 20" barrel. It was as smooth out of the box as the one I had, after I had smoothed it up.
So the quality / smoothness seemed to vary quite a bit from firearm to firearm ,, or at least 5 or 6 years ago with these two different rifles.
Also, with 38spl. it recoils like a .22 and with some of my 158 gr .357 reloads ,, I've choro at 1250 fps out of a 4" revolver and 1675 fps out of the 16" M92.
A fun little rifle , I would buy another in a heart beat for the right price.. Maybe a stainless .44 this time..
