I bought a SP01 Tac out of the used counter at my lgs a couple years ago.. $400, I about ripped the pocket off my pants getting my wallet out..Pistol looked barely used..all I've done to it is the usual, removable trigger pin and trigger return spring extended firing pin and springs, 15 hammer spring all from CGW, I ended up with one of the best DA/SA triggers I've ever felt, it's as if someone had polished the internals, but looking in the frame, there's no evidence that the pistol had ever been taken apart..or that anything had been polished, I don't know if they're all like that, maybe I got lucky.. I don't know..It's a keeper..
