finally got my G2C .45 to the range

not sure how I feel about it yet. will probably be calling Taurus this week. ran 100 rounds through it . on the 10 rnd mag everytime i got to the 4th or 5th rnd it failed to feed , was nosed up on ramp. on the 12 round mag the last round would stovepipe on eject catching the top of the mag. was still stuck when i ejected mag. Ive already deep cleaned it including the magazines. I'm thinking its a magazine issue , any ideas?

as far as accuracy goes , well i kept near all in the 10" circle at 7 yards but they were all over the place so i'm sure its me, i caught myself anticipating the shot alot.
