This is a high capacity magazine for all Glock 9mm Pistols. This magazine extends out of the mag well. We cannot guarantee that all of these magazines will have a textured surface. This particular model features a tan finish. Mfg Warranty - Polymer mag body, lined with a steel sheath and steel reinforced feed lips. These look and work great. This fantastic magazine has a remaining round count window on the back of the mag, just like the original.
