1862 pocket navy

[goodshot]

Good morning, I have an 1862 pocket navy and a 1862 police, the hammer on the navy tends to lock up in the cocked position, when disassembled it will sometimes release .
When compared to the police the timing appears identical.
The 1862 police functions perfectly, load is 15 grains BP.
Anyone been through this?
Best wishes,

Need more info.  Locks up as in you can't pull the trigger, cylinder well not turn???

cock the hammer, pull the trigger, hammer won't release.
Take the cylinder off, hammer may or may not release.
I will try to pull hammer back more slowly as it tends to spin past correct place if pulled too fast.

It can't be in time if the cylinder stop is allowing the cylinder to cycle to far.   If your flat spring (trigger & stop bolt spring) is installed properly (is it upside down?) see if the cylinder hand is to long.   I've not had that kind of problem so I'm guessing.

If the hammer does not fall when you pull the trigger I would look at the sear engagement on the hammer.  I would look for anything obstructing the movement of the trigger.  Since it may or may not fall when you remove the cylinder then I think the bolt is somehow involved with the problem.  Could the bolt leg be holding the hammer?  Hammer spring good and strong?  The cylinder over rotation is a over length hand.  Fix the hammer/trigger first then fit the hand.  Post what you find.  I assume you have completely disassembled this and everything is clean?

You could reassemble with out the hand and see what you get.

goodshot:  This diagram might be of help to you...........

thank you all, as I compare timing of the trouble free one with the one that hangs up I do detect a difference in the mainspring tension, the good one has much more tension.
Thank you all, your willingness to go the extra mile is appreciated.

That's a great exploded view fourBee.

If your pistol was built by cva and is old proly the bolt spring is weak ! If the u change the bolt spring and the cyl over rotates the bolt is not engagin the cyl if you make the bolt engage the cyl and the hammer won't go all the way back the hand is eather not in the right postion becuse the spring on the hand is weak and if  it cockes and won't fall it could be one of two things. The bolt is in the way or  the sear is rubing the hammer. The pistol I got is proly the worst fited I ever seen and the springs are junk even the replacement springs are weak I had to make all of them to make my pistol work
