In the defense of the ksg. I own one and love it. It may not be a military gun, but mines never failed me. I know a lot of the first ones had issues. Also I'm a short guy and it fits me better than my 870 and 500. So the ejected shells don't hit me. Guessing cause it fits me and the way I hold it. Idk. But I personally like the gun.
