Update on the "DISSAPOINTED" situation. Ok, polished both the feed ramps of the lower receivers and the little lip plate of the chamber on the barrels. I was about to order the Wilson Combat mags and still may. The Smith and Kimber Procarry, shot "Just" name brand mags that came with the two pistols the smith is a "Actmag" or something and the Kimber Pro is a "Kimber mag" shot 100 rounds in each with various hollow points and ball some 230 some 200grain and all fed fine, even with me combat "fan firing" as fast as I could go you know where you lock in your arm real tight to your side and use your whole index finger opposite hand and simply go to it. With that "no" jams of like I said on both 200 various rounds.
