I bought my .45 less than a month ago. I have shot 350 rounds of 230g Federal fmj and 250 185g Barnes jhp. I have only had ftf problems with the 13 round extended magazines. Just went out and bought another 9 and 13 round mag. Not one problem with the 9 round mags. Every other time I load the 13 round mags I get a failure. Most ftf is not even attempting to go up the ramp ,three of them got pinched going into the chamber. Don't think I am limp wristing the pistol. Any ideas.
