I have had an 1860 for a few months waiting to be tuned up and have a conversion cylinder added. The action was stiff and gritty, so I finally took it apart last night to see what might be the problem. I noticed several things.
1) The edge of the hand that engages with the cylinder ratchet has a large burr on the end, like it is very soft and cycling the trigger (no dry-firing, but 20-30 cycles of the trigger since new) caused the edge of the hand to fold over. Running a file along an edge seems to indicate the hand is not hardened.
2) The hand cannot come up through the channel in the frame without moving around the arbor. It appears that the arbor was not whittled down enough to allow the hand to cycle through it's range of motion freely.
3) The channel for the hand is REALLY rough on both the front where the hand rubs and the back where the spring rubs
4) The cam that manages the action of the bolt is pretty rough, looks cast. Not sure how much that affects the action. It looks difficult to smooth without messing a few up as practice.
Any suggestions would be appreciated. I think I need another hand, hopefully it can be hardened after it's fit. Also, not sure what to use to resolve the issue with the arbor. I can try and work the arbor or the hand.
