Alright first you have to take the gun apart.
This youtube video is what I used when I first got the gun, so if you don't know how to strip the gun here you go.

Before I start have to apologize for the crappy pics. they were not that bad but I reduced the quality to email to myself, and made them even worse.
Alright so what do you need to work on this trigger? Not alot.
The small screwdrivers are just used as punches, and to pry. The cutters are for taking out the slide release spring, and the dremel is to polish using the compound, as well as chop a coil or two off of the mainspring.
So first step is to take a good look at everything and figure out how everything works. It is really a quite simple trigger group, and nothing to really be scared about. Everything is held together with 3 pins, and a couple springs so remember what it all looks like, as it makes it easier to put back together.
Just a note. Start with it like it is above, with the hammer released. It makes it alot easier with no spring pressure to fight.
Alright first step is to remove the little wire spring that holds the slide release forward when the hammer is cocked. Again with the hammer uncocked there is no pressure on this spring. Cocking the hammer and releasing it will show how this spring works.
Anyways hammer uncocked, and I simply use a small screwdriver to pry the spring out of the hole which will allow it to drop free.
After the spring is gone, you can see a pin holds the whole slide release assembly into place, and that there is another spring underneath it. Keep in mind this same pin holds the trigger in place as well, but at this point you should be able to remove the pin entirely, just don't lose that little spring when the slide release comes out.
Next step is going to be to remove the hammer which again is just held in place by the larger hammer pin in the front of the trigger housing. Just knock out that pin and it will fall out no problem.
Now you can see the mainspring, which is the next thing to come out. I tried getting the trigger out first but it seems the mainspring kinda gets in the way so first lets remove the mainspring. Again the only thing holding this all together is the little pin at the back of the trigger housing. It is just holding the spring from shooting out the back, but now that the hammer is gone it has no real pressure on it. Just knock out the little pin and the 3 piece mainspring assembly will come out the whole in the back of the trigger housing.
After that is out the hammer should just lift out easily. Again be careful here as their is a tiny return spring under the hammer, with a little detent in the trigger housing that it sits in. Make sure you don't lose that spring.

So here is what you should have in front of you.
The pieces that you need to do some work to are the hammer itself, the trigger, and the mainspring.
First the hammer and mainspring get polished on the surfaces that contact each other.
With the polishing be careful to remove as little material as possible. No sanding or filing simply polishing.
Hammer hook here. You can see where I have polished.
Trigger, again you can see where I have polished. Be sure to get the underside as that is where the hammer hook catches.
Lastly the mainspring needs to be cut. I would be careful here as reliability may suffer if you cut too short. So far I have cut 1.5 coils off of it, and have had no issues. I would recommend cutting then testing then cutting again till you get the desired results. There also has to be enough tension here to keep the gun from going off if dropped or knocked so tread lightly.
Alright for reassembly it goes in reverse of teardown but keep an eye on those little springs making sure they are in right.
First the trigger drops in, here I push the pin in only so far as it holds the trigger in, so I don't have to worry about that spring falling out, and you can then slide the slide release back in and push the pin all the way through later. It does take some pressure and shifting to get the trigger seated and the pin to go through because you are fighting the pressure from the return spring. Just be patient.
Notice the pin not all the way through yet.
next the hammer goes in, and just like the trigger you have to push it into place to get the pin through but it is still pretty easy at this point. Notice the connecting rod, and where it sits in relation to everything else. It is bent to go around the trigger and still seat in the mainspring plug.
Now the slide release can go in, again you have to worry about the spring, and seat it correctly. Some pressure and positioning to get the pin through all the way is also required.
Now comes the tricky part. Getting that little wire spring back in place. This takes some prying and I used the wire cutters to do this. Basically lay it in place and then use the wire cutters to bend it up and push it into the hole. Once it is in a little give it a good whack and make sure it is seated under the pin/guide that holds it in place, and gives it the pressure.
Last but not least the mainspring goes in the back end. Make sure the hammer bar seats right into the cup, and that the spring is all put together properly. I put the cut end in the cup, and the little cap on the flat end of the spring. This stops it from seating crooked when trying to push the spring in and seat that final pin. Basically here I put the pin in slightly just so it is ready, and then use a screwdriver the push the spring in, so the pin will clear. Again just takes some patience but nothing special.
And it should all look just like when we started.
