I have fired about 150 rounds thru my 709. It only cycles Remington ammo or at least it did. My past shooting involved firing one or two mags only. Yesterday at the range I fired 2 mags (Rem. 115gr. HP) with no problem. Beginning with the 3rd mag (I was using and reloading 2 mags) I began to experience FTE, FTL and the slide wouldn't close all the way when loading. The fired cases had scratches all the way around. The gun when it fires is accurate. So gonna send it back to Taurus or ditch it. My CCW must go bang.
