Yeaterday at the range I had some 9mm reloads from a reputable local reloading firm. My Glock 19 ate them like candy but my 709 didn't like them at all. Every 4th or 5th shot failed to eject, while the next cartridge tried to load and created quite a jam. I've had no problems feeding the 709 Federal 115 Gr FMJ. Seems to show how some problems can be ammo specific.
