Traditions Kentucky lock issue

[mowolf]

Hi all,

I have a .50 Kentucky made by Traditions having some issues. Lock cocks perfectly out of the pistol, but when installed, it will not cock, and if it does the least little bump will cause it to go off cock. I have two different stocks for it and it does the same thing in both. Any ideas?

Yep, my idea is that something is interfering with the sear movement. Probably a little wood needs removed. Probably in about the same place on both stocks. Could be the end of the sear bar is against wood or the bottom of the sear is contacting somewhere. Maybe some lampblack or lipstick (buy yer own) smeared on the sear bar will show on where ever it's touching.

OK, sounds like the sear isn't moving.

First thing to check: Is the sear arm contacting the wood on the far side of its entrance? Is the sear pivot tight?

Second thing to check, if those check out: Is there something binding the sear spring? Is it contacting wood at all?

The problem may be with the trigger.

With the lock fully installed in the stock the trigger should rattle just a little when the lock is at the half cock or the full cock position.

If the trigger is not loose it is because the top of the trigger bar that pushes against the sear arm is pushing upward on it.
Pushing up on the sear arm (the thing that is sticking out away from the lockplate on the inside of the lock) is the way the trigger releases the tumbler causing the hammer to fall.

If this is the problem it can be fixed by removing the trigger from the stock and filing off just a little bit from the top of the blade that is sticking up.

If the trigger does seem to be loose when the gun is at half cock or at full cock then the trigger is not the problem.

The problem is probably as the others have said, the sear arm is hanging up on some wood inside the stock.

Try giving the lock screw a turn to let up on the lock. I have a pistol that if I tighten the screw too much it messes with the sear. Might have to carve away some wood also.
