They try to fire a 9mm with a 2mm pinfire.
Cool footage, especially later in the video when they shoot a .22lr.
I am curious whether they are using junk 9mm ammo. When the primer fires, it shoots backwards out of the cartridge before ignites the powder. It looks like the primer pockets may be loose, but I have never fired a 9mm like they did.
