Exploded View...

Is this what you get touching off a ctg with a tripple charge of compacted Bullseye?

C'mon, someone had to say it... :p

Assuming its righthand thread it should increase the pull when turned clockwise. lightend to much and you get a gun that doesn't fire reliably.

OK...thanks.....it just that the trigger feel too light for a stock gun.....I think someone has backed that screw out a wee bit......


So proper procedure would be to remove the screw completely, clean it, re-apply loctite and screw it in until I like the feel of the trigger pull ?

Too light and I'd get light primer strikes ....right ?...
 
Many a person has adjusted the strain spring scew in an effort to lighten the trigger. In fact, most often it lightens it to the point where it results in repeated light strikes in DA. Best to leave it nice and firm and get a proper job done by a qualified person who know's how to tune properly. It'll save u a lot of grief in the long run and most likely a heap of embarrassment on the firing line.

I would have to agree with daBear, the Performance Center model 500 I have has an incredibly light trigger from the factory (when fired as a single action). Tuned by folks that know what they are doing. I have twice now had it fire before I was 100% ready, just the slightest touch on that trigger (a little fidget after cocking it) and it's show time! I can't shoot it accurately as a double action ... the anticipation of the bang is too great and I flinch like a little sissy, when firing it as a single action, I know as soon as I touch that trigger, it goes.

OK great...that is my thinking as well......so would turning that screw clockwise increase or decrease the trigger pull ?weight

It's the strain screw.

It's designed to be left turned in tight. It isn't adjustable.

If you want a lighter trigger pull, change the mainspring to a reduced power (Wolffe) and replace the rebound spring to a 14#.

But the downside that you are restricted to Federal SP primers.

On my guns, I have the 14# rebound spring and the factory mainspring.

Do NOT use LocTite.

FWIW I'm a S&W factory certified Armourer for revolvers and pistols.

That part sure is turned in tight...maybe no one has monkeyed with it and the trigger is that good from the factory....
Since I'll shoot any ammo I can find cheap, I think I'll just leave it be.....

I think that's the best. I've bought used revolvers where the screw has been backed off just a few turns and this was enough to make the gun unreliable due to soft primer strikes.
 
The absolute best, all time way to tune a Smith trigger is to shoot the @ss off it. After a few thousand rounds the trigger will be perfect, or at least you'll be so used to it you'll believe it's perfect :D
