History
The SIG P220 was developed in the early 1970s at the request of the Swiss military, which was looking for a new sidearm to replace the aging SIG P210. The P220 was designed with the intention of being a reliable, accurate, and durable handgun. It quickly gained popularity among the Swiss military and was officially adopted as their standard issue sidearm in 1975.
In 1981, the SIG P220 caught the attention of the United States Navy SEALs, who were in search of a powerful and reliable pistol for close quarters combat. After rigorous testing, the P220 was selected as the new sidearm for the SEALs. Since then, it has been used in numerous combat operations all over the world, cementing its reputation as a top-tier handgun.
Design
The SIG P220 is a double-action/single-action (DA/SA) pistol, which means it can be fired using either a single-action or double-action trigger pull. The DA/SA setup allows for a more versatile shooting experience, making it suitable for both novice and experienced shooters. The P220 has an aluminum frame and a stainless steel slide, making it lightweight yet sturdy. This combination of materials also makes the pistol resistant to corrosion, ensuring its longevity.
One of the standout features of the P220 is its traditional double-stack magazine that holds 8 rounds of .45 ACP ammunition. This gives the user ample firepower in any situation. Additionally, the P220 features a fixed barrel and an external extractor, which contributes to its renowned accuracy.
Frame and Slide
The aluminum frame of the SIG P220 is very lightweight, making it easy to carry for extended periods without causing fatigue. It also has a low bore axis, allowing for better control and recoil management. The frame is ergonomically designed with aggressive texturing, providing a comfortable and secure grip for the shooter. The trigger guard is undercut for a higher grip, and the beavertail extension prevents the shooter’s hand from getting too close to the slide during recoil.
The stainless steel slide of the P220 is durable and resistant to wear and tear. It features front and rear cocking serrations, which provide a firm grip when manipulating the slide. The ejection port is slightly lowered and flared, ensuring reliable ejection of spent casings. Additionally, the slide has a Nitron finish, which not only adds to its aesthetics but also protects it from corrosion.
Triggers and Safety Features
As mentioned earlier, the SIG P220 has a DA/SA trigger system, where the first round can either be fired with a long double-action pull or by manually cocking the hammer for a shorter single-action pull. The DA pull requires more force but offers more safety, while the SA pull is lighter, allowing for better accuracy. The reset is short and crisp, making follow-up shots quicker and easier.
In terms of safety, the P220 has a manual frame-mounted thumb safety on the left side, which blocks the trigger and sear when engaged. It also has a decocking lever, which safely lowers the hammer without firing the pistol. The P220 also has an automatic firing pin block safety, preventing accidental discharges if the pistol is dropped.
Sights
The SIG P220 comes with three-dot contrast sights, making it easy to acquire the target quickly. The front sight is fixed, while the rear sight can be adjusted for windage and elevation. However, night sights are also available as an option for low-light shooting situations.
Performance
The performance of the SIG P220 is nothing short of impressive. It has a smooth trigger pull, minimal recoil, and excellent accuracy. The DA/SA trigger system allows for versatility in shooting, and the external extractor ensures reliable ejection. The P220 has been tested and proven to withstand extreme conditions, making it suitable for use in any environment.
Accuracy
The SIG P220 is known for its exceptional accuracy. Its fixed barrel design and tight tolerances contribute to its ability to shoot tight groups at distances of up to 25 yards.
