This is a Glock 19 pre-ban magazine. It features a 15 round capacity of 9mm ammo, "u-notch" and low placement "9mm" marking. It was manufactured before the assault weapons ban went into effect, which required it to have a restricted marking below the caliber. Overall condition of this magazines is very good with only light marks from use. This magazine style would have been an early Gen 2 variation. Buy online today!
