this is a REEEEEELY bad idea for a couple of reasons.
1)its VERY easy to over do and now you have a trigger that will either burst fire or do a mag dump. now you just wasted a fire control group.
2) those contact surfaces on the fire control group are hardened - but only a very thin layer on the surface. Stoning them removes that hardened surface, and now you have a trigger that can - and usually will (google bill springfield trigger jobs) - over time do what i described above - either start to burst fire, or go full mag dump on you.
both are not only safety concerns, but if either should happen at a public range - you could very well end up in serious legal trouble for modifying your firearm in violation of the NFA laws regarding machine guns.
this could not only cost you your ability to own firearms due to the felony, but its also 10 years and up to $250,000 fine to go with it.
lets just say ITS NOT WORTH THE RISK!!
if you need a budget trigger job, you're better off bobbing the hammer, using a JP Yellow hammer spring, and putting a set screw on the pistol grip screw with the trigger adjuster from
JoeBobs to take up the travel.
if you use the JP Yellow spring set without bobbing your hammer, you risk light strikes on hard nato cup primers. By lightening the hammer weight, you increase the speed and offset the spring weight loss.
HTH
Good information and well worth doing IMHO.
