I have been carrying Speer Gold Dot 124gr. Just the regular, my local shop was out of the +P. I want to get the new Gold Dot G2 version but nowhere around me sells it. Anyway I have ran the above ammo in my PC Shield 9mm along with Tula Brass Maxx, Federal 115gr. fmj. and perfecta 115gr. fmj. All of these have ran flawless so far. Never tried any steel though.
