Nice video! I'm going to share that one.
I gave a simple magazine reloading demonstration (without any firing) to my mother's boyfriend just last night. He was defending a limit on mag capacity saying having to reload takes enough time that lives could be saved. I obviously disagreed, pointed out how a shooter gunning down unarmed people in a gun free zone can very quickly change magazines no matter the capacity.
He continued to argue his point, so I gave him a little demonstration using my Shield. I explained how the action of the gun worked, how on the last shot the slide remains back and what the slide release does. So, with magazines emptied, I simulated how the slide stays back after the last shot.
I then dropped the mag, loaded the second mag, and dropped the slide. Then I told him how a competent shooter could count his rounds, and before firing the last round reload, not having to mess with the slide at all. Again I gave him a reloading demonstration.
I think he was shocked. Out of the blue with no prep I was able to very quickly release and reload my mags. It was like I could see the walls of misinformation come crumbling down around him. He changed his tone after that. He conceded that magazine limit might not be as important as he thought.
I'm glad I had my Shield, with limited round capacity, on me last night. I feel it better demonstrated my point using a low capacity gun.... A gun with NY SAFE magazine capacity.
