New SIG SAUER X-Series Modular Pistol in 9mm and .40 S&W

    SIG SAUER (Germany) has launched a major new line of modular competition pistols. The line has 9 base models, 7 special/accessorized models, and 20 modular accessories. The new X-Series pistols are based on the SIG P226 X-Series and I believe supplants the old SIG P226 X line.


    The main line has three basic models. The X-Short model has a 4.4″ barrel, the X-Five has a 5″ barrel and the X-Six has a 6″ barrel. Each of these models is available in three different styles. The X-Line Classic style features ergonomic walnut grips. The X-Line Match style features black wooden grips, a sport magazine catch and a skeletonized hammer and trigger. The X-Line Super Match features G10 grips and a straight match trigger.


    There are then four specialized pistols. The XPress is a basic entry-level pistol. The X-Five All Round is designed to match the requirements/restrictions on a number of different shooting competitions. The X-Five SO and SAO have non-adjustable triggers (to satisfy rules of certain competitions). The X-Five Open, X-Six PPC Open and X-Six PPC are likewise designed to meet certain competition regulations.

    The accessory market is big and the margins are high. SIG are clever to introduce their latest sports pistol line with a complete set of accessories from day one. There are 20 different accessories that can be attached to the X-Series pistols (although some only work on specific models). They are …

    X Mount Bridges Kits (2) : These allow mounting of optics and come standard with a picatinny rail.

    X Mount Adapter Kits (3): These three kits replace the picatinny rail with optic specific mounts (Docter, Aimpoint and C-More)

    Sights (3) : Three different sight styles are available, including one night sight. Each is adjustable for windage and elevation.

    Slide Side Racker (1): The slide racker replaces the rear sight and allows the shooter to easily rack the slide from the side when an optic is mounted.

    Compensator (2): There is one compensator for the X-Five and one for the X-Short.

    X-Weight (2): These are weights that attach to the under barrel picatinny rail to add weight to the front of the pistol. There is one for the X-Five and one for the X-Six.

    Jet Funnel (2): There are two flared magazine wells. The one is made of polymer, the other of aluminum.

    Triggers (2): Skeletonized trigger and straight match trigger. For adjustable SAO models only.

    Magaizne Catch (1): An enlarged magazine catch.

    Sport Takedown Lever (1): A self-locking lever to prevent the shooter unintentionally unlocking it.

    Grips (4): There are four grips (Hogue G10, Black Laminated Wood, Enlarged walnut grip, Enlarged Black Laminate grip).

    The X-Series design is very attractive. I really like the angular, and subtly futuristic, design. We don’t know pricing yet. I expect it to be high. This is, after all, a high-end range of competition guns.
