For the commercial production and distribution 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 followed by the

Design

The P220 was developed in 1975 by SIG and produced and distributed by 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 (DA/SA) 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 decocking lever and positive firing pin block safety. 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 The Browning Hi-Power is a single-action, semi-automatic pistol available in the 9×19mm Parabellum and .40 S&W calibers. It was based on a design by American firearms inventor John Browning, and completed by Dieudonné Saive at FN Herstal ...

, 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 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 features an automatic firing pin block safety which is activated by the trigger mechanism, similar to the one used in the Czech CZ-038 from the period after the Second World War. The pistol may now be holstered, and can be fired without actuating any other controls. The first shot will be fired in

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 does not accidentally discharge a round while it is cycling. This is called the "trigger bar disconnector". Despite these safety measures, the Sig Sauer P220 has been cited in accidental fatalities. One example is the case of Officer Jesse Paderez of the San Fernando Police Department, California. On 17 July 2002, he was "accidentally shot and killed when his Sig P-220, .45 caliber service weapon, fell to the ground and discharged, striking him in the head. He had gone to the police station to pickup a patrol car...as he walked across the parking lot, his weapon, still in its holster, fell to the ground and discharged when the hammer struck the pavement."


Variants

The original 1975 SIG Sauer P220 had a 'heel-mounted' magazine release lever 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. In 2007, a Picatinny rail was added 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. Also in 2019 a new variant is available called the P220R Hunter that is chambered in 10mm and factory coated with a KRYPTEC camo pattern. The base and R models have an aluminum

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


P220 Compact

A recent variant 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.

P225 / P225-A1

The SIG P225 is a more compact version of the SIG P220. A new German police standard issued in the mid-1970's 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, the HsP, that never went into full production.) Walter Ludwig was involved in the design of the Walther, SIG-Sauer and Mauser entrants in the German Police selection. Each German state was free to buy whichever pistol it wanted to. Initially, the P220 was submitted; the P225/P6 was a revision 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 a 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 were imported into the United States. Because of its compact size, the P225/P6 is quite readily usable for
concealed carry Concealed carry, or carrying a concealed weapon (CCW), is the practice of carrying a weapon (usually a sidearm such as a handgun), either in proximity to or on one's person or in public places in a manner that hides or conceals the weapon's pr ...
. In states with limits on magazine capacity, the P225/P6 was usually in high demand. Most have a push button magazine release located behind the triggerguard, though they (but not the later P225-A1) were also available with a heel-mounted magazine release lever as used on the original P220, which was not a popular feature in the American marketplace as it makes magazine changes slower even though it greatly reduces the chances of an accidental magazine release. The heel-mounted magazine release lever also reduces the incidence of lost magazines in combat as a result of speed reloading magazines, as is common with the push button magazine release which only requires the user to push this button to eject the magazine rather than drag it out by hand as one must do with the heel-mounted magazine release lever. ;P225-A1 P225-A1 was introduced by SIG in 2015. It was based on the P225, with a number of refinements. Notably, the place of origin on the slide was

. There was a new contour to the frame, a short reset trigger, a milled slide (the earlier one was stamped), and two barrel lengths (one standard and the other threaded for a suppressor). The suppressor model came with high sights. The P225-A1 was discontinued in late 2019.

(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, while some of the later P220 Compact variants were available with an extended grip tang. The P245 is no longer manufactured by SIG, having been replaced by the P220 Carry and the P220 Compact.
