Pietta 1860 army half cock issue

hi:

I have a Pietta 1860 Colt Army that I have had for over a year and I have put over 1000 rounds through it.

Today at the range, I started having issues at half cock. When i went to the half cock position, the cylinder would no longer rotate freely, only about 1/4" and then stop. I took the pistol apart and it appears that the notch that holds the cylinder is now coming up at half cock. If I just pull the hammer away from the cylinder about 1/2", the cylinder rotates freely.

What do you think is wrong? Worn parts? (I assume that I can get spare parts at Cabelas). Are these parts hard to swap out?

thanks in advance:confused:

Pietta 1980 half cock issue

Fingers:

Thanks for the info and diagram.

When u mention spreading the legs on the bolt, can u be more specific? ( I have not taken my pistol apart yet, and it is hard to see from the diagram what is required)

Thanks for your help!


Also, do you or anyone else have a step by step disassembly procedure?
 
1000 rnds through it and it hasn't been fully broken down?? It might just need a good cleaning. Fouling could build up on the frame wall and prevent proper cycling of the bolt.
Dissasembly 101
1. Remove 2 top screws (either side of hammer),and one bottom screw that retain the grip and remove the grip & grip frame piece.
2. Loosen the main spring retaining screw and remove the spring (keep hammer uncocked).
3. Remove 3 screws holding the triggerguard in place and remove same.
4. Remove split leaf spring under the trigger guard.
5. Remove 2 screws holding in the trigger and bolt on the side of the frame, remove those parts.
6. Remove hammer retaining screw, lower hammer into the frame to allow removal of hand and hand spring, then remove the hammer through the top of the frame......easy-peasy!!
Assemble in reverse order.
 
It could be cause it's fouling causing the problem, not knowing his shooting and cleaning procedures. I've gone over 1000 rounds in my match guns without having his problem though.
