I made the plunge into black powder a few months ago and picked up an Armi San Marco 2nd Model Dragoon along with an Investarm "Hawken" from a local seller.
Recently, while messing around with the Dragoon, the cylinder started to over-rotate as the hammer would pull back a bit further than full cock. I'm pretty sure the bolt wasn't engaging the cylinder correctly. So I pulled everything apart and inspected the internals. Unfortunately, it looks like someone got a little happy with a bench grinder on a few parts -- at least I hope they didn't come from the factory that way. It also hadn't been cleaned in awhile, so I thought maybe there was just too much gunk preventing things from cycling like they should.
When I removed the trigger/bolt spring from the ultrasonic cleaner and wiped it down, one of the legs broke off. The slot cut between the legs was left square, so my guess is it created a stress riser that was bound to break at some point.
Since I need to replace the spring, I figured it'd be good to go ahead and replace a few of the other components. I found trigger/bolt springs that will work, but it doesn't appear many other original ASM parts are available. I have the tools to fabricate a few of the parts on my own, but I'm not sure the ones I have are up to spec, so copying them may not work.
Does anyone know where I can source ASM parts aside from the usual places that pop up in a Google search?

- Trigger/Bolt spring - Can purchase and modify the Uberti equivalent.
- Trigger - The Uberti replacement appears to match.
- Hand - The hand, spring, and pin apparently need to be purchased separately. I can't find a source for the pin.
- Bolt - Doesn't appear to be available anywhere.
