I took the Chiappa 1892 in 44-40 out at last and had a few minor issues. The ejector was cut too square and would not close over the case rim so the action literally would not close. A bit of stoning on the extractor, which is easily removed without disassembling the rifle, and that was cleared up. Then I was getting FTF on about every third round, which eventually cleared up on its own. I attribute this to a 'phantom' chunk in the firing pin channel. This past weekend it worked like a Swiss clock and proved to be accurate with a box of factory loads purchased locally.
On another note, and there is a cast boolit thread on here, it did not like the initial batch of Hornady Cowboy Action 205 grain boolits I tried. The shots were all over the map with even some key holes. Turns out, when I measured their diameter (advertised on the web and on the box as .427"), they measured .425". How Hornady can market this boolit I do not know. Otherwise I shoot a lot of Hornadys with fine results. Long story short, after I cleaned the nasty lead deposits from the bore, I have some .429s on the way for future endeavours.
My overall impression of the Chiappa is very good indeed.
