In return Honor Defense posted this in the Youtube video comment
Honor Defense has always complied with industry testing standards. Our products passed the ANSI/SAAMI Z299-1996 requirements for Abusive Mishandling, which includes a Drop Test and Jar-Off Test. These tests were conducted internally and by an independent facility approved by the State of California. Any firearm can discharge when dropped. Like any user of a firearm, users of Honor Defense’s products must handle firearms in a safe manner. No one should attempt to perform a drop test outside of a professionally-controlled environment. We have recently viewed this video in which a person creates an accidental discharge and we are investigating. Honor Defense remains committed to providing the most comfortable, accurate, safe, and 100% USA firearms.
