History

The SIG P220 was developed for the Swiss Army as a replacement for the SIG P210, which had been developed during World War II; in service it is known as "Pistole 75" (P75). For development of the P220, SIG collaborated with J.P. Sauer & Sohn of Germany, thus, the P220 and all subsequent pistols from SIG are properly known as SIG Sauer pistols.

In 1975, Switzerland became the first nation to officially adopt the P220 as the "Pistole 75" (P75) chambered in 9 mm Parabellum. Other nations to adopt it for military use include Japan and Denmark though only to special forces. It was succeeded by the SIG Sauer P226. hms1 2

Upon completion of their military service, the officiers of the Swiss armed forces can obtain ownership of their P220 service pistols by paying an administrative fee of thirty Swiss francs. hms2

The P220 operates by the locked breech short-recoil method pioneered by John Browning. On firing the slide and barrel are locked together until, after a few millimetres of rearward movement, the barrel is cammed down at the rear after the pressure has dropped enough when the bullet has departed the barrel, whereupon the slide completes the rearward stroke ejecting the spent cartridge. The recoil spring then propels the slide forwards, stripping a round from the magazine, and in the last few millimetres of forward movement, the barrel is cammed upwards at the rear, locking the slide and barrel together again. Instead of the locking lugs and recesses milled into the barrel and slide of other Browning-type weapons as the Colt M1911A1, Browning Hi-Power and CZ 75, the P220 variants (and many other modern pistols) lock the barrel and slide together using an enlarged breech section on the barrel locking into the ejection port. This simplifies manufacture but has no functional disadvantages. The slide of the P220 series is a heavy-gauge sheet metal stamping with a welded-on nose section incorporating an internal barrel bushing. The welding is so well-executed it is almost impossible to detect. The breech block portion is a machined insert attached to the slide by means of a roll pin visible from either side. The frame is of forged alloy with a hard-anodised coating. While designed for ease of production, the SIG 220 series is of the highest quality and there is no compromise in durability or functionality compared to pistols produced using more traditional methods. The SIG P220 series incorporates a hammer-drop lever to the rear of the trigger on the left side, which first appeared on the Sauer 38H before World War II. After chambering a round, the hammer will be cocked, so for safe carriage the hammer drop is actuated with the thumb, dropping the hammer in a safe manner. The P220 also introduced a firing pin block safety which is activated by the trigger mechanism - similar to the one used in the M1911's Series 80 pistols. The pistol may now be holstered, and can be fired without actuating any other controls. The first shot will be fired in double action mode, unless the firer chooses to manually cock the hammer. Double action trigger pressure is around 12 - 14 pounds, and subsequent shots will be fired in single action mode with a lighter trigger pressure of around 6 pounds. There is no separate safety lever to manipulate; the hammer drop is the only safety device. As with other double action pistols such as the Walther P38 and Beretta 92F, some training is required to minimize the difference in point of aim caused by the different trigger pressure between the first double action shot and subsequent single action shots when the hammer is cocked by the rearward movement of the slide, but this is easily overcome.

Variants

The original SIG P220 had a 'heel-mounted' magazine release located behind the magazine well, but a design revision on newer SIG P220s moved the magazine release to the left-side of the grip, behind the trigger. The P220 was then later modified again with a redesigned slide, grips, and other minor changes to the frame. Even more recently was the addition of a Picatinny rail to the dustcover as standard.

The SIG P220 also comes in P220R and P220ST versions. The base and R models have an aluminium alloy frame with a stainless steel slide (if made by SIG Sauer in the US; German made versions still use a blued, stamped steel slide); the ST model has a stainless steel frame and slide. The R and ST models also have a Picatinny rail, beneath the slide and barrel, allowing for fitting of accessories such as lights or laser sights. The P220 was initially imported to the United States as the Browning Double Action (BDA) and then as the P220. The P220s sold under the Browning Arms Company marque in the USA c. 1977 - 1980 had the heel-mounted magazine release until Browning discontinued it from its product line in the early 1980s; the discontinuation from the Browning product lineup was its poor sales and its then-'space age' appearance (similar to the AR-15/M16 assault rifle). These particular P220s (or Browning BDAs) will have the stamping scroll which reads 'Browning Arms Company Morgan, Utah and Montreal PQ' on the left hand side of the slide and 'SIG-Sauer System Made in W. Germany' on the right-hand side with the serial number scrolled beneath. It was offered for sale in 9 mm, .38 Super (a rare model), and .45 ACP. However, all modern P220 variants are only available in .45 ACP. Until recently, all SIG P220s were DA/SA and featured a de-cocking lever (and no external safety) just forward of the slide catch.

This has changed with the introduction of DA only, DAK, and SA only models. The DA only and DAK models do not have a de-cocking lever or safety, and the SA only models only feature an M1911 style external safety. SIG has also introduced the SAS (SIG Anti-Snag) model - which is dehorned, has no accessory rail, and is designed for concealed carry - and the Elite model, which includes the new short-reset trigger, a beavertail grip, front strap grip checkering, and front slide cocking serrations.

P220 Rail

The P220 Rail (or P220R) is effectively the same as the P220, but it has a Picatinny rail on the dustcover. The P220R usually represents the more recently produced P220s, and has now become the standard P220.

P220 Carry

A new P220 with a shortened barrel (3.9") and slide, but a full-sized frame. It is available in double action/single action (DA/SA), single action only (SAO), and DAK double action variant. All models with the exception of the SAS concealed-carry version come with an accessory rail.

P220 Compact

A new P220 variant recently released. It comes in four versions: Blued with beavertail, stainless (two-tone) with beavertail, blued with rail (no beavertail) and stainless with rail (no beavertail). It features a shortened slide, and a compact frame and has a capacity of 6+1. It is possible to use the 8 round magazines of the P220 Carry which will give it an 8+1 capacity. Adapters are available to cover the portion of the magazine which protrudes from the bottom of the grip. It is essentially a replacement for the discontinued P245, and is meant to address complaints about the P220 Carry's full-size frame in a concealed carry pistol.

P220 Combat

The two "Combat" models, the P220 Combat and P220 Combat TB (Threaded Barrel), are available in DA/SA or DAK. Their frames are colored "Flat Dark Earth" in compliance with the Combat Pistol program. The Combat model comes with night sights, a Nitron-finished slide and barrel, phosphated internals, and a Picatinny rail. The TB model features an extra 0.6" on the barrel, and external threads to accept a suppressor. The P220 Combat is only chambered in .45 ACP, and is supplied with one 8 round magazine and one extended 10 round magazine.

P220 ST

A version of the SIG P220 handgun made by SIG Sauer with a reversible magazine release, stainless steel slide, and stainless steel frame. Changing to a stainless steel frame from the lighter alloy frame normally used is meant to reduce felt recoil. The ST models are typically bare stainless (all "silver"), though SIG Sauer has produced Nitron finished (all "black") ST versions for police department trial and evaluation (T&E) guns.

P225/P6

The SIG P225 is a more compact version of the SIG P220. When it became apparent that the Swiss Army was looking for a new pistol, plans were set into motion. The SIG P210 was just too costly to manufacture, and the Swiss Army wanted a cheaper semi-automatic handgun, but it still had to provide excellent functionality and a double-action trigger. SIG, in cooperation with a German arms company, J.P. Sauer & Sohn, developed a new pistol. In 1975 the A75 (as it was known in the Swiss Army service), or 9mm SIG-Sauer P220, debuted with various new and inventive features. It utilized a single column magazine holding eight 9 mm rounds and had a 3.9 in. barrel. A new German police standard, in the mid-1970, prompted SIG-Sauer, Heckler & Koch, and Walther to develop new pistols that met the standard: the Walther P5, the SIG-Sauer P225 (known as the P6) and the Heckler & Koch P7. (In addition, Mauser had a design that never went into full production). Each German state was free to buy whichever pistol it wanted to. Initially, the P220 was submitted; the P225/P6 was created to conform with the mid-1970s West German police requirements for its standard service pistol. At the time of development, the P225 was also designed for use with the .45 ACP cartridge in mind; if the P225 had the .45 ACP option, it would have became a possible concealed-carry firearm similar to its P220 Compact series introduced in the late 1990s. The SIG-Sauer P225 was the least expensive (due mainly to the inventive design) and received the majority of the orders. To be able to manufacture that many handguns, SIG acquired a controlling interest in J. P. Sauer & Sohn in Eckenfrde, Germany to manufacture parts for the P220. This is also where all P225s were manufactured. Many Swiss police forces also use it, as well as the Swedish Police. Also, it is the main sidearm carried by boarding parties in the Canadian Navy. The Swiss Guard, the protectors/military of Vatican City, also use the SIG P225 as one of their sidearms. Some Swiss police pistols have a different magazine release, similar to that from the P220. The only difference between the P6 and P225 - the P225 (which was adopted by US civilian law enforcement) has a lighter trigger pull, whereas the P6's trigger pull is heavier. The P225 has tritium fixed sights; P6s had fixed sights only. Genuine P225s manufactured for the West German Police will have a 'P6' stamp on the right side of the slide. A new police standard was adopted in Germany in 1995, and the P225 is in the process of being replaced. German police pistols can be identified by the hammer, which has small 'ear' or 'hook'. According to section 7.7 of the German manual, the cutout is the Deformationssporn, which means eformation spur. This was a requirement of the West German Police for all their pistols, regardless of manufacturer, to alert police armorers if the pistol was dropped on its hammer. Many of these surplus German police pistols have been imported into the U.S. recently. In U.S. states where hi-capacity magazines are prohibited, the P6/P225 is usually in high demand.

P245

The SIG P245 variant is chambered only in .45 ACP (hence the name) and was developed primarily for the US market as a civilian's concealed sidearm, or as a police backup weapon. The SIG P245 has a reversible magazine release giving the user the choice of operating it with their left or right thumb. It normally takes 6 round magazines, but can also accept the 7, 8, or 10 round magazines designed for the P220. A grip extender is available for use with these longer magazines.

The P245 is no longer manufactured by SIG, having been replaced by the P220 Carry and, more recently, the P220 Compact.
