Here's the Chiappa mini-Sharps with scope
I've had this for several years now, and I've had two problems. First, in the rear sight base, there's a screw that tensions the spring that holds the ladder up or down. The screw stripped. I couldn't figure out what thread pitch it was, or find something that size to try, so I tapped the spring for a larger size, dressed the head appropriately, and blued it. End of that one.
The second, I was firing one day, worked the lever, and instead of moving open and staying there, it flopped. First thought was "Crap, the spring broke." Happily, no. Here there's a spring under the forend that tensions the spring that the lever works against; the head of that screw stripped. Apparently the head was a bit small for the pressure involved, and it finally broke. There I was able to find a screw with both matching thread(yes, it was metric, and Ace Hardware) and a wider, stronger head. No problems since.
I like it. It's fun to shoot, accurate, and out to 100 yards or so- with appropriate ammo- I'd have no problem using it for deer(lighter loads for smaller stuff).
