I hope that FTF means failure to feed. Here is the deal. When I load the Glock 19 10+1, the second round gets stuck. I have to manually pull back the slide to get it the rest of the way in there. After I finish that magazine and slap a new one it (10+0) it feeds everything fine. This is with Blazer Brass 115 gr.
Is this common? Might it be the ammo?
