I've shot a bunch of Champion in 9mm and .45 acp. I've never noticed a problem. Perhaps it is gun specific. That is one of the drawbacks of semi-autos.
Sometimes a specific gun doesn't like a specific brand of ammo.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
no guns = might makes right
