i only have two pistols with me at my home.
glock 21SF (.45) and a sig 226 (the 9). i shoot them back to back frequently. i am much more accurate with the Sig. i think it is the recoil..or less recoil.
either way..you cant go wrong. i only bought the glock because my brother entire swat team carries it. i wanted to see what the fuss was about.
