Went shooting with a buddy today who just bought 2 new 10mm 1911s, a Springer Elite Operator and a Colt Delta Elite. We put about 100-150 rounds into each one and had terrible FTF issues with both guns. Both he and I had the problem when firing both pistols. We were shooting a variety of ammo, mostly Magtech range type stuff but also some Bear Bore and some Hornady 300g. Problems with all. It seemed to come down to the magazines: the ones that came with the SA and two extra WC mags the purchased were the ones that FTFed, maybe 30-40% of the time. These had the standard WC-style flat metal follower. However, the Colt mags with the sculpted metal follower and another one (maybe also came with the Colt) with a rounded plastic follower were problem-free. I should have taken some pics, but didn't. Any thoughts on this? He was understandably a bit bummed. I never have owned a 10mm 1911 so I'm just curious if they are picky on mags. Any thoughts welcome and thanks.
