Not enough data/background on this incident, frankly, and claiming that a glock "can just go off in a holster" is alarmist, at best. It's pretty obvious either the guy has a bad holster or something got stuck in there. Back when Dean Speir had his website up he used to cover stuff like this and it always involved some huge operator or equipment failure. One guy holstered his glock with a lanyard from his raincoat jammed into the holster; when he sat down the lanyard keeper tensed up and pulled the trigger, basically a massive failure on the part of the guy with the gun.
I've carried glocks on and off for over a decade now, and when I started it was with 7 dollar foam holsters, lmao. It's not a problem if you VET YOUR GEAR and
circumstances. And practice with it, unloaded.
Also most glocks are more than a 5 lb pull, btw. I rarely if ever see one break 5 without at least a disconnector change and some polishing. Even my G19 with the oem minus
connector in it still meters out at 4.95 lb. And it's not "long" but it sure as hell isn't short either.
If you want to see short, light pull and shit your pants, then get a Steyr M9 and we'll talk about short. That is literally the only striker fired gun that kinda scares me a bit...
