The problem is not the trigger. The trigger rides against the sear in
the lock. The sear holds the tumbler and hammer till you press the
trigger. If you take the lock out of the gun and *** the hammer. Look
at the notch in the tumbler with the sear holding it. You will find the
notch is very deep. The deep notch is why you have a lot of creep before
the hammer is released. You can soft solder piece of brass shim in the
notch. Use a shim that allows the nose of the sear to have complete hold
on the tumbler. That will give you a crisp break when you press the
trigger. If you want to convert the lock back to original just remove
the shim. DON'T grind the notch.

The sear spring at the back of the lock is also to strong . That
controls the trigger pull. If you lighten the spring tension on the
sear, the trigger pull will be much easier. You can order a new sear
spring from Dixie Gun Works in Tenn.

The lock on a trapdoor is basically the same lock they used on Civil War
Muskets. The hammer is different.

If you are leary about doing this . Do you have any muzzle loading clubs
in your area. Some one at the club can help you.

It is your gun so if you want to shoot it go ahead. Care for it the way
you would your other guns and it will outlast you.
