Re: Trapdoor trigger job

Uhhh, I would suggest finger exercises to build up strength might be a better solution.

About all that can be safely done is to polish the surfaces where the top of the trigger engages the rounded bottom of the sear bar, and that as well. Also the nose of the sear that engages the tumbler notch and the face of the tumbler notch. BE CAREFUL NOT TO CHANGE THE ANGLE ON THE SEAR NOSE OR TUMBLER NOTCH! None of that will do much to change the pull required, but will smooth it up somewhat to make it smoother.

Someone with more skill COULD make minor changes to the angle of the sear nose and/or tumbler notch and the changed geometry will change the trigger pull weight. However, it is important to be careful not to change the angles to the point where it will not hold the engagement.

An alternate solution is to switch to a "set trigger" where a light pull on the trigger will activate various levers and springs to trip the sear. This usually involves adding a fly on the tumbler, and is somehwat complicated. Reproduction single set triggers are available from The Rifle Shoppe and I think a few other sources as well. Additional inletting is required on the stock under the trigger plate to accomodate the added parts, so please do not do this to a nice collector gun!
