XD MOD2 3.3" 45ACP Extended Ported - Black Nitride
These are some of the finest match grade barrels made! Because of the care exercised in manufacturing and unwillingness to compromise on any step of the process. We use the finest material available (type 416 Stainless Steel) Machining processes are accomplished on CNC equipment for close-tolerance production. Heat treating is done in a vacuum furnace for clean, consistent hardness of 43-45Rc Barrels are bored and rifled using ECM process (electro chemical machining). This process produces greater accuracy (+/- 50 millionths of an inch) and a superior finish (16 RMS or better). It also creates less stress button, broach cutting, resulting in a more accurate barrel with greater durability. The end result is a good-looking, top-quality barrel with consistent, accurate and long-lasting performance. Threading or porting will extend the length of the barrel about 1/2''.
