I conceal carry a Glock 19 everyday...i don’t understand how this happened. The odds of his clothing getting tangled at just the right angle to pull the Glock trigger has to be astronomical. Some thing tells me he was careless with his trigger finger. Only way that gun will fire.
Ditto, 35+ years with firearms, no ND. I too have a G19, never had an issue. When properly maintained Glocks do not fire unless and until someone pulls the trigger.
