I bought a used .45 Pedersoli Tryon rifle, from Hyatt gun shop. It's not the Creedmore, it's the 1 in 48 twist .45. I did a search and I saw Zonie has or had one of these and I think it has the same trigger issue, where it cannot be fired unless the rear set trigger is set, but it's not clear if some were made this way and some not. This one is from 1992, someone added fiber optic sights which of course are coming off. I'm looking for opinions , I hope this shoots well with PRB because I was looking to use this as a PRB 100 yard target rifle. Mounting a diopter rear and globe front sight seems kind of overkill for a 100 yard round ball rifle ? Or is it? I had originally intended to just order a set of period 3/8" dovetail barrel mounted sights and use it as an 1840s era target piece. I'm not likely to take it past 200, more like 100. I always thought of tang sights and diopter sights as stuff for long range bullet rifles.
