Bought a Taurus '94' that looks a lot like a .22 tracker a couple of years ago, to use as a trainer for some family members. Model number has never appeared anywhere, but it's a pretty good package, seems bigger frame than most 94.
Anyhow, got it for $329 in stainless, worst DA trigger I've ever found on any Revolver, ever, and 60 years of shooting I've seen some poor ones, but the SA pull was nice maybe just a tad mushy.
Did a little research and found out that in .22 revolvers Taurus has taken the attitude that with so much faulty .22 ammo on the market, they beefed up the springs for a harder hammer fall, shows mostly in the DA pull.
Theory is/was that DA shooting is close and needs to be super reliable first accurate second, and that if accuracy matters, anyone would use SA anyhow.
Always meant to go in and 'fix' it but somehow that never happened.
Kept the gun and now 5-6000 rounds later the DA pull is still heavy but even and smooth, quite usable. And that's the only trigger job it's had (I'm guessing a number of internals are of work hardening steel).
The SA pull has done nothing but get better, very crisp.
Very well pleased with my 'mystery' Taurus 94.
As always JMHO, YMMV
