Glock needs to include a warning on all sides of the box and also etched onto the slide that their handguns MUST be used with the proper holster.
uh, no.
Every handgun must be used with a proper holster that has retention and completely covers the trigger guard. Pocket carry/pants carry without a holster is a ridiculous decision with any gun. Glocks aren’t any more dangerous than anything else. There are just people like this guy who can’t be trusted with firearms. Or chainsaws. Or cars, for that matter.
