For what it's worth, I did my own using the instructions here: http://www.geocities.com/molonlaberkba/triggerjob.html
There's still a little bit of creep, but I'm going to try the set screw in the grip well trick for that. So far I've been very happy with it. I didn't have any polishing compound so I used some toothpaste. It could still use a little polishing but overall it's still pretty good compared to a stock trigger. The very 1st time I tried to shoot it, the hammer strike didn't pop the cap...but every single time after that it's gone off fine.
I don't have a trigger scale so I can't quantify the change exactly. Bottom line though, you're changing 2 springs so it's really not a huge risk. Even if you fudge it up totally, it's only going to cost you about $3 worth of parts.
