It works on most variants, but not all.
Know what you're working with before committing.
The .22 LR and .327 Federal versions, for example, use 'extra power' main springs (16-lb and 18-lb, respectively, I believe). Both 'require' the extra power for reliable ignition, due to the 22 version having to crush case rims and .327 Federal using small rifle primers (thicker/tougher than small pistol primers).
Spring kits in any of the .22 LR or .327 Federal variants often result in misfires, or complete inability for the revolver to fire.
Even 'standard' variants that are rough may have ignition issues after going to 'reduced power' springs.
That being said... There's no replacement for a proper trigger job. A properly polished, crisp, smooth trigger can make what started as an 8-lb pull feel like 3-lb.
A full action job can also smooth things out, so that the reduced power springs are no longer marginal from fighting too much friction.
Using springs for a 'trigger job', in my opinion, is like putting new tires on your car/truck to smooth the ride, because the suspension is broken. ...Might make a person feel better, but the real problem is still there.
