Has anyone experienced any issues with failure to feed Winchester ammo in there sig 1911? This is only the second 1911 I own so am still new to the 1911 world but I had 2 to 3 failure to feeds in the 100 rounds out of my new sig. One was caused by the round itself I think as I retested it and got the same result after putting the round back in the magazine. The second round is what worried me. Could it be the factory mags are just bad? I didnt have my rra with me so I couldent switch out mags to test buit the rra never jamed in any way with standard winchester fmj (wally world ammo). The second failure to feed happened with 4 rounds still in the magazine, the first would reoccurs be it the first or the middle round whenever I reloaded the mag, so im pretty certain it was the round. Anyway any ideas appreciated. I have two "power mags" coming in the mail so maybe that will help.
