That guy is a douche of the first degree. The Glock, like most firearms, fires when you press the trigger. A broken striker spring will not fire a glock any more than a an unplugged toaster will electrocute you. Unfortunately, there are millions of glazed over idiots who believe ANYTHING posted on Youtube. Glock ought to sue him and Youtube for defimation.
In life, strive to take the high road....It offers a better field of fire.
