probably opening a can of worms here but like to hear some feedback..I have S&W revolvrs in .44 mag and been playining around a little with trigger pull using strain screw...1 turn out really makes a diff and cannot see any problem doing it this way...a little less tension is not going to hurt tension on spring or gun..lots of guys swear by filing the end a bit so it fully seats..which makes sense as screw will keep winding out with percussion over time and that will be a issue, misfires, spring waffling etc...so what say you all?.. easier than all new spring?:evil:
 
That is a legit way to adjust. The Strain Screw should be tight when finished. You can also re-arc the Mainspring.
 
The only issue is that proper operation and optimum results requires tuning the rebound block spring to match the mainspring. About half the trigger pull resistance comes from the rebound block spring.

You'll also not get the nicest and smoothest build in trigger pressure to motion by ignoring the rebound block spring.

So all in all I'd say "no", it's not worth it. Get a proper spring kit and do the job correctly.
 
Or spend the money to have the work done by an artist who will properly polish all contact surfaces, use proven spring weights and provide you with a perfect trigger - with a warranty - for not much more. We have one of the best revolver smiths in North America here in BC - all you'd need is a short term ATT. Give Murray Charlton a call and he'll quote you a price that will probably have you asking why you'd bother doing it yourself. While he's at it he can take the end shake out, set up the lock up, clean the whole thing like new and give you a revolver that really performs - probably better than you thought possible.

^^^ agreed... Too many home wannabe gunsmiths fool around with the strain spring which does make for a lighter trigger pull but also results in an unreliable pistol most of the time. Consistent light strikes and frustration are not worth it. Spend a few bucks and get the proper trigger job/springs. As mentioned, Murray is one of the best and revolver 'smiths are increasingly difficult to find in this country. Well, I meant good revolver 'smiths are hard to find. Lots of guys who 'think' they can fix it but turns out otherwise in the end.

Turning the strain screw is free, nothing is cheaper than that. I agree that having a 'smith do the work is worth it if you want the ultimate trigger, but there is nothing wrong with a bit of tinkering at home to see if the owner can be happy with a bit lighter pull or really wants the quality of work that a 'smith provides.
