My buddy has a g22 gen4. He claims the ejected casings are flying back behind him and sometimes hit him in the face.. I'm not sure if he is exaggerating about the contact with his head but my question is.. What direction should the casings be flying out, behind him or to the right like say my hk's do.. He swears the gun is faulty and needs to be sent back to glock.. It's hasn't even been broken in yet I tell him. But he is bullheaded and thinks he knows everything
