Apex J-Frame Duty/Carry Spring Kit – - Guns & AmmoGuns & Ammo

This from Guns and Ammo magazine. Anyone do this or have it done? I'm an idiot, so I'd pay someone to do it, but was wondering, once done, are you happy you did it? Supposedly takes the pull from 12 lbs to 8 lbs? Any experiences, good or bad, out there?
