Trigger work question...
« on: December 24, 2008, 12:48:10 AM »
 I recently got a T/C Cherokee with a single trigger. The trigger has some side-slop, but I can shim that up with small washers.

 However, It also has front-to-rear play. I see that there's room to add a small leaf spring on top of the brass housing/guard to push the trigger forward, but is there another fix that might work better?

 Is adding a trigger return spring to muzzle-loaders common practice? I imagine I'm not the only one who doesn't care for a floppy trigger ???

I am not sure if I understand the front to back problem.  Is it rearward over-travel?  If so you may be able to drill and tap a hole in the rear of the trigger guard to limit over-travel rearward.  I would think that if you add a spring to keep the trigger in a more forward position it may change the trigger pull.  Just a thought.

 It does have some overtravel, but that doesn't bother me much. It's the slop that's there when it's cocked that's annoying. As it is now, the trigger can move back and forth freely, so I have to take up this slop before it engages the sear. It breaks cleanly after that point. An added spring would only need to be strong enough to hold it forward lightly. Then the trigger would feel somewhat like a two-stage and be more uniform in its function rather than being able to move into different positions.

 Just wondering if anyone had done a similar fix.

If the trigger has both lateral and front to back wobble, without movement in the sear, it would indicate the trigger pivot hole, or pin have worn, or the pivot hole in the trigger is oversized.
    Check to see if the trigger has slop on the pin.  If it does, replacement of both the trigger and pin would take care of the wobble.

Or, you could explore ways to shim up the existing parts ?

 The gun is in new condition so there's no wear, just poor manufacturing. The pivot pin is indeed smaller than the hole in the trigger. Also, the width of the trigger is about .030" smaller than the slot in the guard housing, so that doesn't help matters much. These two items are allowing the side-slop.

 In addition to the above, the notch in the trigger where it engages the sear is wider than the sear itself, allowing front-to-rear movement.

 Anywhoo, I've figured out how to fix all of the above with a larger diameter pivot pin, shim washers and an added return spring.

 Thanks
