my son was shooting up some older factory 180 grain .40 cal FMJ yesterday and out of the last magazine, he had two failures to fire, which he ejected, and then a kaboom. He was not hurt at all, but says it was very loud and the pistol locked up tight.
He brought me the pistol, but not the cases or ammo or magazine. I managed to get the Glock apart, and it appears the recoil spring is broken. I have been shooting Glocks for years, and though I have heard of this, I have never seen it before.
Very glad to hear he didn't get hurt..
