Unless your rolling with all federals and a 10lb hammer spring you wont have to worry about a sub 2lb SA pull. I think on average you'll see a 2.5-3.5lb SA range which you'll find to be just right once you get to learn a DA/SA gun. It takes a bit of time to move from a striker fired to a DA/SA platform but with a little dry fire you'll learn to love it.
I hate to rain on your parade but the factory left the gun far from "Xtreme" and taken care of. Yes the majority of the parts are there, but so is the stacking and zipper feeling in the trigger pulls. Do your self a favor and take the time to polish the internals, you'll be glad you did once your complete.
