This is a Glock 19 pre-ban magazine. It features a +2 Glock extended floorplate with a total round capacity of 17 with square notch and low placement "9mm" marking before the assault weapons ban went into effect which required it to have a restricted marking below the caliber. This magazine style would have been the final pre-ban variation prior to 1994. Magazine is representative of the one you will receive. Buy online today!
