I changed springs(hammer, sear) and got FTFs due to a lighter strike that wouldnt set off the rounds, at least thats what I figured. (PS the pull was a lot nicer!.) Its very easy to swap out the springs, but you have to put your shoulder into it when you put it back together (ps tape the disconnector down to keep it out of the way). The sear, mag release spring is what I kept and went back to OEM for the hammer, and that was the end of the failures.
