Default Longer Hammer spring tension spring screws.

I had my 686 action done and a Wolfe #2 spring kit installed several years ago by a local Gunsmith but the trigger pull seems abit light after running 50 rounds through it.
The hammer spring tension screw is still tight so I wonder if longer screws are available to help increase the trigger pull without doing anything else to the gun?
I can probably get used to it!
The action is smooth as butter!

Are you referring to double action or single action as being "light". Did you have ignition/reliability issues while shooting?

Ultimately you need to be comfortable with the action and trigger pull weight but you might want to either purchase or borrow a trigger pull scale from Brownell's or MidwayUSA. They are relatively inexpensive and they will tell you what your single action pull weight is without guessing. The typical one only goes up to 8 pounds so for the most part they are useless for double action pulls. I am guessing you are talking about the single action pull though.

Call Wolfe, they have longer screws available that you trim to suit your taste.

Barring that, a 'small' washer will shim the screw out or a solid one mad out od brass. Have done it both ways. BEWARE of screws that have been 'trimmed' however.

It's possible your action job included a shorted strain screw.

Maybe all you need is a new unaltered strain screw?

A grade 8, 8-32 cap screw fits S&W strain screw threads. I keep the original spring and screw, and make a custom screw for strutted springs when setting up for competition. A half inch screw can be ground to shorten, and if you go too far, just make another. I buy at Home Depot.
If I sell the gun, I just put back the original spring and screw. The leaf spring and screw can be changed without opening the action; just remove the grips.

I have no reliability/ignition problems. The double action is fantastic but the single action seems too light, guessing maybe 2 1/2 lbs. I will look into a trigger pull gauge and Wolff longer strain screws. I'm not going to touch the action.

The longer strain screw and the resulting heavier hammer tension will not help the resolve the problem with the light single action measurement.

You can easily resolve that specific problem, however, by installing a slightly heavier rebound slide spring. The rebound spring was likely changed to a lighter spring when the action work was done, and re-installing an OEM rebound spring will raise the single action back to a level above 3 pounds, without any other modifications or changes.

Trigger jobs usually are stoning the parts that rub and cause resistance which is felt when pulling the trigger. By stoning these parts you are creating several years worth of normal wear. Then when you add several more years worth of "normal wear" to the action you may have exceeded the wear limits. When this happens you may have to have the parts adjusted or replaced. Please do a Push Off test to see if you have a potential dangerous situation in single action. If not, take a fired primer and remove the anvil and loosen up the strain screw and slip the primer cup over the tip of the strain screw. This will act as a shim to extend the length of the strain screw against the main spring. This might cure the problem.

There is no push off, locks up tight. Has only about 50 rounds through it since the spring and action job.
I probably need to check the trigger pull with a gauge. The action is so smooth it may feel lighter than it really is.
I like the DA as it is!

I like the fired primer as a screw shim idea! I will give that a try!
There is no Push Off problem, locks up well!

As armorer951 pointed out, that extra information is very meaningful & points to your rebound spring probably being modified & too light.

Hammer spring tension is not a main component of SA trigger pull weight, the rebound spring is.

Try a new factory rebound spring first.

I am going to try the spent primer shim on the tension screw as suggested above but if that doesn't help the gun comes apart and the trigger rebound spring gets replaced!
I just ordered a trigger pull gauge to see what I've really got!

Sorry for being redundant, but I'm going to take one more shot at this.....adding more tension to the hammer spring will only serve to make your double action pull heavier. It won't do a thing for your perceived "light" trigger pull rating in single action.

Correct tension on the interface between the hammer notch and the bevel on the trigger is provided by the correct (a.k.a.: OEM) rebound slide spring.

Default Happy with the results!

I left the spring tension screw alone and before I messed with anything
I purchased a Wheeler trigger pull gauge to see where the DA & SA trigger broke after having a professional gunsmith do an action and spring job on my 686+.
It feels lighter because it smooth as butter.
The DA breaks at 7lbs 8oz and the
SA breaks crisp at 2lbs 12oz!
I am very happy and can live with that! 😉👌
