RE: Winchester 94
The M94 trigger mechanism, like a lot of other lever action triggers, is a simple engagement of the trigger nose and the hammer notch. It is easy to make it better, and keep it safe also. Hammer notch depth is reduced slightly while keeping CONTACTING angles the same, and polishing the engaging surfaces with hard Arkansas Stone files. I did my Marlin 336, and smoothed it up quite well. I ended up with a 4# pull with no creep.
Any competent gunsmith can do this job.[8D]
