Ruger trigger

There is a Wolff spring-kit for the GP-100 available from http://www.dillonprecision.com (among other vendors). The kit will include several springs, each one providing a different trigger pull.
The new springs are very simple to install. Remove the revolver's right-side wooden grip. Underneath it you will see a small pin and a stainless-steel circle about the size of a dime. Remove the small pin and set it aside. Press the dime-sized circle inward to release the left-side wooden grip, and then remove the circle completely. Slide the rubber grip off the revolver's frame.
You will see a spring inside the frame. The spring has a small follower underneath it with a hole that will accomodate the small pin you removed from the grip. Double-check that the weapon is unloaded, then cock the revolver's hammer. The spring will compress significantly. Insert the small pin into the hole in the follower, and release the hammer. The spring will remain compressed, and you can easily remove it.
Install the new spring. Assembly, as they say, is the reverse of disassembly. Be sure to test fire the weapon to insure that the new spring is sufficiently strong to set off the primer for the ammunition of your choice.

As an aside, you might find that rather than "lightening" the pull, stoning and pollishing the innards works the wonders you seek. Any qualified smith can perform this service for you, which involves reducing the friction between trigger and hammer components. You can perform some of this work yourself by firing the weapon A LOT, both with and without ammunition.
The difference in perceived trigger pull is amazing... seems like it's 50% lighter, when it's actually closer to 10% lighter. Nice and smooth, you'll be very happy after a well done job.
Also, there are fewer concerns for liability if you don't "customize" your weapon with what prosecutors call a "hair trigger".

The Wolff spring pack dropped the single action pull on my GP from 4.5 to 3 lbs. The pack contains three different weights for both the trigger & hammer return springs. I can't remember which springs I ended up using, but had problems with misfires until I switched from CCI to Winchester primers.

Replacing the hammer-return spring is just that simple. If you can change your car's oil, install a new card into your PC, or field strip a firearm, you can replace a hammer-return spring.
On a side note, another post mentioned lightening the GP-100's single-action trigger pull. Keep in mind that replacing the hammer-return spring will not lighten the single-action trigger pull, because the single-action pull does not compress the hammer-return spring. When firing the revolver with single action, you compress the hammer-return spring by cocking the hammer. Because a double-action trigger pull cocks the hammer, you can lighten the double-action pull by replacing the hammer-return spring.
Regarding smoothing up a double-action trigger by dry firing thousands of times, I wonder how much of the perceived trigger-weight improvement comes from the mechanical smoothing of the action, and how much of the improvement comes from strengthening your trigger finger! I wonder if prosecutors frown on strong fingers as much as they dislike "hair triggers".

Any time you replace or alter springs to change the trigger pull on a defense gun, fire at least 50 rounds with the defense ammo. Any, repeat any, misfires, it's back to the drawing board with a new spring.
It is also a good idea to load the gun and store it in the freezer for a day and then fire it. Cold can cause misfires when springs are lightened.
A good trigger pull will cost time and money, but don't let it cost you your life.

Just bought a nearly new GP-100 .357 revolver. I saw somewhere in TFL a post about how to lighten and smooth out the trigger action, sure can't find it now! Could someone advise please?[/quote]
Like others have said, get the spring kit. I ended up using the heaviest hammer spring and the lighter trigger spring in the kit. I also lightly polished parts of the trigger and hammer assembly. That plus lots of dry firing has made a very smooth action. I compared it to a new GP100 this weekend while at a show. The difference is amazing. None of the work was difficult since the gun comes apart so well and is rather simple in design.
