Years ago I dropped the trigger on my guide gun from 10-4 pounds, by doing a sear job (this was after paying a gunsmith, who merely added bushings to the spring, and I ended up with countless FTFs. Never used the guy again). Don't want to do the same on my son's 336, but that heavy factory pull is abysmal. Just wondering how easy an after-market trigger assembly switch is to do at home, or is this a definite job for my gunsmith?
