So I actually just took about a half hour, and ripped apart the trigger group on mine.
It is very simple and straight forward, and should be easy for anyone to do with a little bit of mechanical skill.
I couldn't find anything online about disassembly of the trigger group, or anything remotely close, but like I said it is pretty straight forward. Just be sure to study how it works, and what goes where, prior to ripping it apart.
I polished the contact surfaces on the hammer, and trigger(no sear) and I also cut a coil off of the hammer/main spring. I am going to go back and forth from the work bench to the range to see how much can be cut off with out affecting the reliability of the hammer/firing pin striking the primers, but it is pretty stiff, and the hammer hits pretty hard, so I assume I could remove more. Don't want to take any chances though.
Really this is an idiot proof trigger job, as long as you stick to just polishing the trigger, and hammer surfaces, and use the hammer/mainspring to decrease the pull weight. Even if you cut it too short, and started seeing light primer strikes, the design of the mainspring, and how it fits in the trigger group, would allow for you to shim it with washers or such in order to make the spring stronger again.
I will put up a little tutorial when I figure out how much can be chopped without affecting the reliability.
