Sig Sauer SP2022 40 S & W

 Sig Sauer SP2022 40 S&W

    The SIG Pro is a short recoil operated, locked breech semi-automatic pistol. It uses a traditional Browning cam-operated locking system. The barrel locks into the slide via enlarged ejection port.
The frame is made from polymer, with detachable grip panels. Grip panels can be easily replaced and are available in several different sizes and shapes.
The overall design is slightly different from earlier SIG-Sauer pistols such as P220 or P226, as there is no separate disassembly lever on the frame and the slide stop lever looks quite different.
The standard SIG Pro does not have a manual safety but it does incorporate a decocking lever (lowers the hammer without striking the firing pin), trigger-bar disconnect (disconnects the trigger when the slide is out of battery), automatic firing pin lock (does not free the firing pin until the trigger is depressed) and a hammer safety intercept notch (prevents the hammer from striking the rear of the firing pin until the trigger is depressed).
    The Sig Pro comes standard as a double-action/single action pistol with 10 lb and 4.5 lb trigger pulls, respectively. Double-action only conversion kits are also available from SIG.
     SP 2022: A modified version of the SP 2009/2340. It entered service with the French Police and Gendarmerie in 2002 for a planned service life of 20 years, hence the name. 460,000 rounds have been used for testing it before adoption by a sampling of future users and modifications of the SIG Pro followed to produce the 2022. It is available in 9x19mm, .40 S&W and .357 SIG. The pistol is fitted with an integral Picatinny rail instead of the proprietary rail of the other models and the front trigger guard is shaped differently to allow a finger hold. It can also be equipped with a threaded barrel and detachable suppressor and the fixed open sights are dovetailed into the slide.
