The XD Mod.2 5" Tactical Model packs 16 rounds of 9MM ammo in each of its two included stainless steel magazines. While it's a double stack design, it's not too thick to carry. This Tactical Model features a full five-inch hammer forged carbon steel barrel and is treated with Melonite to stand up to moisture, sweat, and other undesirable conditions over the long haul.The slide is made from Melonite-treated carbon steel too. Included is a Springfield High Hand grip near the beavertail and below the trigger guard allow you to put support close to the bore line to minimize muzzle flip. The GripZone contours and texturing are specifically designed to provide maximum purchase at specific points where your hands and fingers require the most contact. The sights are a fiber optic front paired with a low profile combat rear sight.
