The SIG Sauer P220 is a semi-automatic pistol. Designed in 1975 by the newly formed partnership of SIG (Schweizerische Industrie Gesellschaft now Sig Holding AG) and J. P. Sauer & Sohn, it is manufactured by SIG Sauer GMBH in Eckernförde, Germany, and by SIG Sauer, Inc. in Exeter, NH, USA.
Not to be confused with SIG P210 series, which licensed the Petter-Browning system from SACM of France in 1938, the SIG Sauer P220 was developed in 1975 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 partnered with J.P. Sauer & Sohn of Germany, thus, the P220 and all subsequent pistols from SIG and J.P. Sauer & Sohn 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 (general issue) and Denmark (which has the earlier P210 in general issue) only to special forces. It was succeeded by the SIG Sauer P226.
Upon completion of their military service, commissioned officers of the Swiss armed forces can obtain ownership of their P220 service pistols by paying an administrative fee of thirty Swiss francs.
The P220 was developed in 1975 by SIG and J.P. Sauer & Sohn. A new locking system which is known as the SIG Sauer system was introduced as well as a number of other innovations. This nomenclature is found on the Browning BDA version of the P220 sold from 1975.
The SIG P210 (now manufactured as the SIG Sauer P210 in the United States) is a licensed copy of the French Model 1935 which is the Petter Browning design. Petter had removed the loose fitting barrel bushing and the tilting link of the John Browning M1907 design, but retained the grooves on the top of the barrel which engaged similar grooves in the interior of the slide. SIG licensed this design in 1947.
The SIG Sauer design went further by having no grooves in the slide or barrel. Instead an enlargement of the chamber locks directly on the ejection port of the slide. The double action/single action trigger design of the P220 is also a SIG Sauer innovation similar to the J.P. Sauer & Sohn 38H pistol. Further design refinements include a hammer decocker level and positive firing pin block safety.
SIG Sauer System
Instead of the locking lugs and recesses milled into the barrel and slide of Browning-derived weapons such 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. The SIG Sauer System (embossed on the side of the Browning BDA) is a refinement of the Petter-Browning system.
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 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-anodized coating. 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 I. 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 features an automatic firing pin block safety which is activated by the trigger mechanism, similar to the one used in the Walther P38. 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 user chooses to manually cock the hammer. Double-action trigger pressure is measured at approximately 12–14 pounds, with subsequent shots being fired in single-action mode with a lighter trigger pressure of approximately 6 pounds. There is no separate safety lever to manipulate; the hammer drop is the only manual safety device. As with other double-action pistols such as the Walther P38 and Beretta 92F, some training is required to minimize the difference 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.
SIG Sauer refers to their safety systems as a Four Point System. The four types of safety are:
- the de-cocker, which allows the shooter to lower the hammer safely, while there is a round in the chamber. When the de-cocking occurs, the hammer is lowered but it still stays away from the firing pin.
- the safety notch, prevents the hammer from striking the firing pin accidentally.
- the firing pin has its own safety, which makes sure that the pin will not move forward. That is, until the trigger is pulled, at which time the safety is removed and the pin is pushed forward to meet the cartridge's primer. This third safety is also the gun's drop safety. Even when dropped from a reasonable height, with a round in the chamber, the gun will not fire.
- the slide has a notch, which separates the firing pin from the cartridge. Unlike the aforementioned firing pin safety, this one is there to make sure that the gun doesn’t accidentally discharge a round while it is cycling. This is called the "trigger bar disconnector".
The original 1975 SIG Sauer P220 had a 'heel-mounted' magazine release located at the rear of the magazine well and a lanyard loop which was typical of handguns made for Police and Military purposes. Newer SIG P220s utilize a push button magazine release to the left side of the grip, behind the trigger and do not have lanyard loops. The P220 was then later modified with a redesigned slide, grips, and other minor changes to the frame.
More recent[when?] was the addition of a Picatinny rail to the frame under the barrel as standard on all models whose number ends in R. The major difference in slide design, between the older model SIG pistols and the current production, is that the older model slides were stamped whereas the current production models are milled on a CNC machine. The stamped models have an end piece at the muzzle end which is welded in place, to complete the slide. Additionally, the older stamped slides feature a removable breech block. This breech block is pinned to the slide with two hollow roll pins, one pressed inside the other, with their split ends opposed. The newer milled slides are a one-piece unit and do not have a removable breech block.
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 Sigarms 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 due to 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 available in .45 ACP and, as of January 2015, 10mm Auto. Until recently,[when?] 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.
The P220 Rail (or P220R) is effectively the same as the P220, but comes with an equipment rail located on the forward end of the frame of the firearm for accepting accessories such as a weapon light or laser sight. While the provided rail is similar to the Mil-STD-1913 Picatinny rail design, as implemented by SIG for this gun it has a proprietary cross-section form that conflicts with some early design Picatinny-compatible equipment. The P220R with its rail has become the standard configuration of the majority of recent and current production P220s.
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.
A recent variant[when?] that 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.
The two "Combat" models, the P220 Combat and P220 Combat TB (Threaded Barrel), are available in DA/SA only. 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 chambered only in .45 ACP, and is supplied with one 8-round magazine and one extended 10-round magazine.[citation not found][citation not found]
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.
P220 Classic 22
This model's primary purpose is as a practice or range pistol. The Classic 22 model replaces the typical stainless steel centerfire slide assembly with a lighter aluminum rimfire slide chambered in .22 LR. The Classic 22 also has a different barrel, guide rod, and recoil spring than the larger caliber models. It incorporates the same frame and operation as centerfire P220 models. The Classic 22 model is available as a stand-alone firearm or as a conversion kit to an existing centerfire P220. Likewise, conversion kits (the SIG Sauer X-Change Kits) exist to convert a .22 LR P220 into .45 ACP.[citation not found] The conversion can be accomplished by field stripping the firearm and replacing the slide assembly and magazine—a process that can be accomplished in minutes.
The Classic 22 use a 10-round polymer magazine in lieu of the steel magazines used by the centerfire models and conversion kits.
The P220 Classic 22 should not be confused with the SIG Sauer Mosquito .22 LR pistol. The Classic 22 is a full-sized P220 while the Mosquito is modeled on the P226 but is 90% of the size.[citation not found] Another difference is that the Classic 22 is manufactured by SIG Sauer while the Mosquito is made under license by German Sport Guns GmbH. The size difference means that the Mosquito cannot be converted "up", and full-size SIG Sauer pistols cannot use the Mosquito's slide assembly.

Current version is P225-A1  The SIG P225 is a more compact version of the SIG P220. A new German police standard, in the mid-1970s, 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. 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 Eckernförde, Germany to manufacture parts for the P220. This is also where all P225s were manufactured. 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 "deformation spur". This was a requirement of the West German Police for all their P6 pistols, 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. Because of its compact size, the P225/P6 is quite readily usable for concealed carry. In U.S. states where standard capacity magazines were prohibited, the P6/P225 was usually in high demand.
P225-A1 was introduced by SIG in 2015. The new model was introduced based on the P225 with a number of refinements. Notably the place of origin on the slide is now SIG Sauer Inc. Exeter, NH. There is a new contour to the frame, a short reset trigger, a milled slide (the earlier one was stamped), two barrel lengths, one standard and the other threaded for a suppressor. The Suppressor model comes with high sights.
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. One of the major differences in construction between the P245 and the P220 Compact is that the P245 was only built using the older stamped steel slide design with a removable breech block.
The P245 is no longer manufactured by SIG, having been replaced by the P220 Carry and, more recently,[when?] the P220 Compact.
