SIG-Sauer P220 (Pistole 75 / Model 75)

History of SIG-Sauer P220 (Pistol 75 / Model 75)

The SIG-Sauer P220 is a line of semi-automatic pistols of Swiss origin, also produced in Germany. As the Swiss government maintains very strict export laws for firearms, SIG (Swiss Industries) has partnered with Germany-based J.P.

Sauer to allow the production of handguns in Germany, circumventing Swiss restrictions and opening the arms to a larger market. The production of the P220 therefore falls under the banners of SIG von Neuhausen-am-Rheinfalls (Switzerland) and J.P. Sauer & Sohn or Eckernforde (Germany), hence the name SIG-Sauer.

This fusion of manufacturers resulted in a weapon system - albeit mainly from SIG - with some modifications with Sauer's participation. The P220 series spawned a larger line of successful semi-automatic pistols, from the P225 to the P229.

The number of operators has increased, including Canada, Iran, Japan, Switzerland and the United States. The West German police were the former Cold Army during the Cold War.

The core of the P220 is an improvement over the original P210 system that appeared in the late 1930s. The SIG Group received several patents in France and began to design and develop its own automatic pistol, which eventually became the P210. Featuring a locked breech pattern not unlike the original Browning design, the P210 is a solid and reliable weapon. The P210 is capable of firing both 7.65mm and 9mm Parabellum cartridges, the latter of course requiring some internal modifications. Five versions of the P210 eventually appeared and were issued to the Swiss Army as the main sidearm.

Such is the quality of the pistol that many budget-conscious military and law enforcement personnel still do not have access to the P210, suggesting that the weapon is too expensive to buy in bulk.

Therefore, the P220 was developed on the same principle as the previous P210. However, the P220 is designed to be a faster, cheaper version for concerned buyers. The slide-to-lock feature was simplified from the original P210, and the weapon's design was aided by a computer-controlled mechanism for precise measurements.

The weapon was launched in 1975, the same year it entered service with the Swiss Army as the main weapon. In service, the Swiss dubbed the weapon the "Pistole 75" or "Type 75," replacing their P210 in the process.

Internally, the P220 features a locking breech system and short recoil, each based on the very successful John Browning system. For safety reasons, the P220 doesn't disappoint, it comes with a shelling stage, an automatic firing pin safety lock (patented by design), a safety intercept notch, and a trigger lever disconnect to ensure the weapon doesn't fire accidentally . Flip-flops are inherently double-acting, but can implement single-acting functionality when needed. Thanks to this integrated four-point safety device, there are no manual pawls. When firing, the slider and barrel - because they are locked together - move back along the frame.

Then push the barrel down until the bullet leaves the barrel. The rearward movement of the slider ejects the spent cartridge and causes the recoil spring to function. The recoil spring now pushes the slider forward, and the resulting action strips a new cartridge into the firebox.

The barrel now slopes up and joins the slide in a forward motion, again making the gun ready to fire.

The P220 retains an overly clean look consistent with the SIG-Sauer brand. The slides are rectangular with smooth, flat sides. The pistol grip fits perfectly in the average human hand and provides a good grip, and the grip ensures that the gun remains in the user's hand while firing. The hammer can be seen as a protrusion on the back of the frame. The barrel is mounted in a chute, is 4.40 inches in length, and features a right-hand twisted 6-groove rifling pattern.

The barrel length of the entire gun is 7.79 inches. The upper part of the trigger is hinged and protected by an elongated trigger guard. The ejection port is located at the top center of the frame with a notched rear sight and a front sight above the muzzle.

Picatinny rail supports were added later. Overall, the P220 proves to be a solidly constructed sidearm, specifically designed to withstand the rigours and abuse of everyday operations in high-intensity jobs.

The main cartridge for the P220 became the 9x19mm Parabellum, these magazines were loaded in a spring loaded 9 round detachable magazine (also available in 7 or 10 rounds and different calibers), the magazines Cassette used in patterned pistol grip. Muzzle velocity is rated at 1,132 feet per second.

The empty weight of the entire weapon system is 1 lb 13 oz. The magazine release was on the back of the magazine slot, but was later moved to the left of the pistol grip behind the trigger.

Since then, the P220 has proven itself to users in security, law enforcement, military and special forces. It comes in two main versions, called P220R and P220ST. The R model uses an aluminum alloy frame with stainless steel rails (stamped steel if made in Germany, otherwise made in the US), while the ST model is made from a stainless steel frame and rails.

Variations in the P220 series include the P220 "rail" with a Picatinny rail system on the dust cover to accommodate a variety of sights, scopes and accessories, the P220 "carry" with a shorter 3.9" barrel and Accessory rails, P220 "compact" (itself in four variants), two P220 "combat". 45 Military Grade ACP Models, P220 "Classic 22" for .22 "Long Rifle" Cartridges, P225/P6 Compact, P245. 45 ACP for the Swiss Army and West German Police (P6), P245 for the US market.

45 ACP.

The P220 has since been replaced by the P226 model on the SIG Sauer line. When first imported into the United States, the SIG-Sauer P220 was sold under the name Browning Double Action (BDA). These are in 38 Super, original 9mm and .45 ACP calibers.

Since then, the P220 has only served as a .45 ACP weapon.
