There are a few companies that can tune up a 391 trigger group. Cole, Angle Port and Timney Gunsmithing can "help" the 391 trigger but even on its best day it ain't going to feel like a P or K gun trigger. Timney or Alum(?) made up a pull/release for another friends 391 and he shoots it well. I started going with J&P Products when I replace my 391 springs. They advertise their springs are made from "best chrome silicon wire available". They even offer P gun coil springs.
The above mentioned pull/release trigger was not correct. The trigger was a release/release as the 391 trigger only has one hammer.
