OK, I've been wanting one of these babys for years now. The funds are almost there. Now what is the difference between a Nat. Match trigger and a standard trigger? Can a standard trigger be worked up to a NM? Or do I need to keep saving to get the loaded version? And what all does Springfield do to justify the $400-$600 difference between the base model and a NM? I almost went with a Garand, but I want a Mag. fed rifle.
