This is the chandler person's webpage:Anybody notice that someone from Chandler, AZ is offering a "magic" (his word) trigger lightening job for the FS2000? He is advertising it as just over 5 lbs pull. Wonder if he's replacing the springs? I had no knowledge of this prior to today, have no knowledge of what he is doing to achieve this "magic", and am not associated with him in any way, in case anyone is wondering.

If you notice he claims:You need to send me your hammer pack to do a bit of machine work on it and do my magic. It is not like the other modifications that I do to lighten the trigger as this one is not a DIY fix. I wish it was but its not.
It sounds like something a whole lot more drastic than spring changes. That's not to say new springs aren't involved, but I'd guess that it's more significant than that.
