This is the kind of rhetoric I don't like though because it's not true. Glocks don't go bang "EVERY TIME". They fail just as often as any modern pistol made by a reputable company. But this is the narrative people keep pushing as if Glocks are some superweapon immune to failure.
It's certainly true with my Glock 20. It's gone bang every time I've shot it. Not claiming it has immunity to failure, just that it hasn't failed.
