There are several things a person can do to lighten the trigger on a model 94.
The first that some do is to use either #4 wall anchors or .22lrf snap caps(Tipton) and practice dry fire. Do this somewhere from 500-1000 repetitions ( not all at the same time obviously) and things smooth and lighten out.
There are some who change the springs out, but I had misfires with the Wolff ones.
The 94 is my main understudy gun to my larger centerfire revolvers. It's a 5" barreled beauty.
I also own a 990 which shoots very tight groups at 25 yards using CCI solid Mini-Mags.
The 990 has one of the smoothest, crisp, and light trigger pulls on any revolver I've ever felt. The 990 is a 6.5" barreled revolver.
