"I came accross one that seemed really weak. It made more of a poof and had little or no recoil. If I were really new to this and was not pre warned I may have continued shooting.."
This is intriguing,if the round released "little or no recoil"then it surely was not ejected and the cycle would have stopped right there,"continued shooting" under normal circumstances then would not have been possible. Only negligence
could at that point attempt to fire the pistol again.
