Hey, Dragline--wanna do a good trigger tune on that Smith? Polish the bottom and left side of the rebound slide, shim the hammer boss (Ron Power shims), carefully ream the inside tunnel on the crane and install an endshake bearing; then replace your rebound spring with a 14 lb. Wolff spring. Smooth as silk, with a reliable ignition.
I have already stoned and polished the rebound slide, as well as installing a 14lb rebound spring from wolf. The lighter 14lb rebound spring makes a world of a difference without sacrificing trigger reset problems. What do you use for reaming the inside of the crane? I gave it a quick go through with the red polishing compound that comes with the Dremel tool I have then finished with mothers mag polish. Also ill have to check out the shims you mentioned.
