So I bought a couple of Mec-Gar 8 round mags for my new 1911 (Girsan). I was having an issue with the OEM mag when it was fully loaded (8 rounds) it would fail to feed in the pistol. The round would be stuck between the mag and the chamber. It only happened on fully loaded mags. Bought the Mac-Gars and was-lah all fixed. Now to go shooting tomorrow
