Recently I installed a new Kepplinger set trigger. Two things you shoud be aware of. The first stage is not adjustable and need to be done before installing the set trigger. Like mine had a 6lbs trigger and I honed it down to 30oz. Then I installed the trigger. After some considerable load testing the set scews (2) shot loose and I lost the set trigger function.
This required a comlete take down and coating the screws with epoxy to make them stay put and readjust the whole system.
During the first installation it came apparent that the Kepplinger trigger did not reach the sear extension being 0.024" short. Which I resolved by soldering a 0.025" shim to the underside of the sear extention. This might not have happened if I had worked on the sear rather than the hammer. But the hammer notch is a lot easier to work on than the sear.
Depending on you skills this is not just a simple change
of parts, and adjusting the regular trigger pull is no picnic
either. One needs to build a precice jig to do a trigger job from 72oz to 30oz. for proper parts relation.
Otherwise get a smith that knows how to do a complete job which I would say adds another 250 to $300 to the job. Most standard Ruger#1 triggers are unnessesarely heavy.
