This was a simple and fun job.
Picked up the screws at Lowes and I followed this thread for direction:
http://www.airgunhome.com/agforum/viewtopic.php?p=56061 (http://www.airgunhome.com/agforum/viewtopic.php?p=56061)
I liked the big photo and used it as reference and to make sure I put the parts in their proper orientation.
I have the first stage set how I like it. I also replaced the factory trigger spring with a shorter lighter spring from a mechanical pencil.
The over travel is set as well, but for me this is not something I worry much over. I've got it adjusted to about a 2 or 3 pound pull. Need to measure at my friends house.
The trigger itself really bugs me. I'm going to dremel the sides down to make it narrower and also round the edges better. I wish I could find a metal trigger.
Now, the "third" screw was the one that makes all the difference.
I followed the I instruction on the link exactly as written and it worked out really well.

Bryan and Associates has the brass trigger for $22. The used disco I bought came with one. I've never shot a disco/2260 factory trigger so I can't provide info on the differences but I do like it very well.

Do be carefull with the third screw as all you are doing with it is decreasing the sear engagement, do smack it with a rubber mallet a few times for a "bump test".
John
I did that quite a few times. I know exactly what that third screw does :)

tried doing a search for their website but the links that come up are dead.

What is the length of the 4-40 cap screws? Is the housing just plastic? Did you tap with a tap set or just the screw itself?

Just use the link I used for directions. VERY EASY.
I did not use the exact screws though. I did use 4-40 screws but they were plain steel machine screws. 2 will be 1/2"long. The third will be 3/8" long. Get them at Lowes or Home Depot.... or Fastenal stores.
Here's the third screw already installed:

I will remove this screw later when I find a black socket head screw. It looks much nicer than the bright stainless steel screw.
I used a 3/32" drill bit for the spot in front of the trigger guard. Yes the housing is plastic. There is a casting mark right in the middle where you need to drill, just take your time.
The other two holes are already there and the 4-40 screws thread right in.
Here's the bit:

The screws are held snugly in the holes. You may want to add some blue Loc-Tite if you want, but this is an air rifle with zero recoil.
Be careful adjusting the third screw, make sure the air rifle is pointed in a safe direction when adjusting it.
Again, just read through the directions first, then have at it. If you don't like messing with the third screw, just remove it. The drilled hole is very tiny and virtually unnoticeable.
