Sticking on half cock notch

[48mauser]

I bought a Spanish made caplock pistol with a nonset trigger from the classified board, it sticks on the half cock notch unless you really jerk the trigger. What could be the cause and the fix? Is there any way to convert it to a flintlock and who may have parts?

it could be just crudded up. take down and clean well and check the release notches with the action out.

Does the trigger release the hammer from the full cock position? Or are you trying to release the hammer from the half cock position? The hammer should NOT fall if you are pulling the trigger at half cock! If the sear is catching on the half cock notch when released from full cock, then the tumbler needs some work. The sear should clear the half cock notch when releasing from full cock. Take the lock out and see what is happening. It should be apparent what needs to be done to make it operate correctly.

Sure, you have to replace the drum (assuming it has one) with a vent liner. Then find a lock the same size or a tad bigger to fill the recess. Some percussion locks have flintlock twins and it is sometimes possible just to swap out for the needed parts (lock plate, frizzen, frizzen spring, and hammer. I have done that very thing with a Dixie Mountain rifle) Many muzzle loading supply houses should have the parts you need. It would probably be almost as cost effective to sell your pistol and buy a flintlock, rather than buying parts to make the change, especially if you need a new lock.
