i need some advise here. i have one M1A that has a GI trigger and it has a really nice crisp second stage pull. my other M1A has a commercial trigger group with more creep and doesnt have the crisp break the other one has. i know Springfield offers to do a "national match" job on the trigger but i dont know if they just make the trigger smoother or if they actually improve the second stage of the pull(crispness). i heard that in order to do that you need to modify the hammer. anyway, any thoughts would be great. thanks.
