I had totally forgotten how user-hostile the standard factory Glock mag release was.
Had the G19 out and was running rounds through it and... dang... I had to roll that thing around in my hand and poke the crap out of it seriously and deliberately to get the mag to drop cleanly.
Should I mess with some of the "tactical" releases, or can I just go to a 17L/34 release without worrying about my heater spitting its mag out every time I holster up?
