I have a Pedersoli '59 Sharps with the set trigger, which worked very nicely... until it didn't, and I have several questions. When I purchased the rifle, using the trigger without setting it, the trigger pull was really quite awful (long and very heavy) but with the trigger set, it was heaven to shoot. I have several other rifles with set triggers and have not had this issue. The other issue, and more important is that one day I couldn't set the trigger at all. I discovered that the adjustment screw and its spring had fallen out (it's a tiny bugger and, I fear, lost forever.) Does anyone know where, or how to get a replacement (or replacement parts for Pedersoli firearms in general?)? The other part to this question is, will simply replacing the missing parts solve the problem or do I need to do a deep dive inside the set trigger plate to repair/adjust/align any innards? Thank you, in advance, for any and all assistance.
