Your story sounds exactly like mine, three or four lite primer strikes out of a hundred. I stripped the slide and cleaned and inspected several times. Didn't help. Very dis-heartened with this wonderful G26 Gen3, I finally asked a knowledgable range employee and was informed that the slide was not going to full battery causing the lite, off-center primer strikes. The cause was me, not the pistol or ammo. Limp wristing? Not me!.... But the problem went away.
