I had various feeding problems, etc. Once I figured out that problems traced back to the grip safety and the thumb safety, the gun runs fine. My hand was sliding down the grip safety just enough to stop the gun on the third round. The thumb safety was engaging when my thumb inadvertently flipped it during firing.

I followed a suggestion by a forum member and wrapped the grip safety down. I hold my strong hand thumb down with my left thumb; gun runs fine as long as I take care of the safeties.

I've learned the rear sight needs to be adjusted for each type of ammo. Don't just assume it's going to shoot POA.

My Shield shoots rings around the 9mm EZ.
