Danny Dietz rest in peace
The SIG P226 is a full-sized, service-type pistol made by SIG Sauer. It is chambered for the 9x19mm Parabellum, .40 S&W, .357 SIG, and .22LR. It is essentially the same basic design of the SIG P220, but developed to use higher capacity, staggered-column magazines in place of the single-column magazines of the P220. The P226 itself has spawned further sub-variants; the P228 and P229 are both compact versions of the staggered-column P226 design. The SIG Sauer P226 and its variants are in service with numerous law enforcement and military organizations worldwide.
History
The P226 was designed for entry into the XM9 Service Pistol Trials (see also Joint Service Small Arms Program), which were held by the US Army in 1984 on behalf of the US armed forces to find a replacement for the M1911A1. Only the Beretta 92F and the SIG P226 satisfactorily completed the trials. According to a GAO report, Beretta was awarded the M9 contract for the 92F due to better durability during endurance testing and a lower total package price. The P226 cost less per pistol than the 92F, but SIG's package price with magazines and spare parts was higher than Beretta's. The Navy SEALs, however, chose to adopt the P226 later.
Schweizerische Industrie Gesellschaft is a Swiss company and Swiss law severely restricts the export of firearms. Consequently, SIG entered into an agreement with German gun manufacturer (and eventual owner) J.P. Sauer & Sohn to facilitate an export market for their products. For the U.S. military XM9 trials, the P226 was imported by SACO. Interarms took over importing when the pistol was introduced for civilian sales. SIG-Sauer eventually founded SIGARMS, Inc. in the United States, to handle importation of their products. In 2000 the SIG Holding AG sold J.P. Sauer & Sohn GmbH to two German businessmen.[4] The brand name SIG Sauer remained at the J.P. Sauer & Sohn GmbH.
Design Details
The P226, like the other members of the SIG Classic family, 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 millimeters of rearward movement, the barrel is cammed down at the rear. By this time, the bullet has left the barrel, and the pressure has dropped to safe levels, 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 millimeters of forward movement, the barrel is cammed upwards, 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, such as the Colt M1911A1, Browning Hi-Power and CZ 75, the P226 (and many other modern pistols) lock the barrel and slide together using an enlarged breech section of the barrel locking into the ejection port. This modified system, which was devised by SIG, has no functional disadvantages compared to the original system, and has since been copied by numerous firearm manufacturers.[5]
The slide of the pre-1996 P226 was a heavy-gauge mill-finished sheet metal stamping with a welded-on nose section incorporating an internal barrel bushing. The welding was so well-executed it was almost impossible to detect. The breech block portion was a machined insert attached to the slide by means of brazing and a roll pin visible from either side. However, since 1996 production has shifted to CNC machining, and the slide is now milled from a single piece of stainless steel. Therefore the current standard P226 has a black-anodized stainless steel slide. This resulted in a stronger slide, which was necessary to chamber the more powerful .40 S&W and .357SIG cartridges. The frame of all models is made from hard-anodized aluminum alloy. While designed for ease of production, the SIG P226 is of the highest quality.
The standard SIG P226 incorporates a decocking lever on the left side of the frame above the magazine release button, which first appeared on the Sauer 38H prior to World War II, and allows the hammer to be dropped safely. In chambering or firing a round, the actuation of the slide automatically cocks the hammer. By using the decocking lever, the hammer can be de-cocked without actuating the firing pin disconnect, making it impossible to accidentally fire the weapon by using the decocking lever. Furthermore, using the decocking lever makes the weapon "drop safe," which means the firing pin will be blocked from striking a loaded round unless the trigger is pulled. Pulling the trigger and slowly lowering the hammer does not make the weapon "drop safe," and can result in an accidental discharge if sufficient force is applied to the hammer. Properly decocked, the pistol can be holstered safely and can be fired in double action mode by simply pulling the trigger. There is no manual safety to manipulate, as the SIG P226 incorporates only internal safeties. Double action trigger pressure is approximately 10 pounds. Subsequent shots are fired in single action mode with a lighter trigger pressure of approximately 4.4 pounds. As with other DA/SA pistols such as the HK USP and Beretta 92F, some training is required to minimize the difference in point of aim caused by the different trigger pressure between a first double action shot and subsequent single action shots. The hammer may also be manually cocked at any time by the user to fire in single action mode.
Manufacture
SIG firearms are manufactured both in Eckernförde, Germany, by J.P. Sauer und Sohn GmbH, and in Exeter, New Hampshire, United States by SIG Sauer Inc., formerly SIGARMS Inc.
Variants
P226 Rail
The P226 Rail (or P226R) is the same as a P226, but it has a rail on the underside of the frame, just forward of the trigger guard. The P226R's rail has a more rounded contour than the military standard M1913 Picatinny rail and while most Picatinny-rail accessories will fit, not all will. This has now become the standard P226.
P226 Tactical
A P226R with an extended 5 in (13 cm) barrel and external threads to accept a suppressor.
P226 Navy
U.S. Navy SEAL Teams started using the SIG P226 in the 1980s.
The first Naval Special Warfare mil-spec P226 pistols to be offered to the public were the NSW Commemoratives, issued in early 2004. The SIG P226-9-NAVY is a version of the SIG P226 that is produced to the exact specifications of the pistols supplied to Navy SEALs, including special phosphate corrosion-resistant finish on internal parts, contrast sights, and a stainless steel slide engraved with an anchor to designate them as Naval Special Warfare pistols. SIGARMS raised $100,000 for the Special Operations Warrior Foundation through the sale of these NSW serialized pistols. The pistol bearing serial number NSW0001 was sold during a live auction on the nationally syndicated Laura Ingraham radio show for an additional $25,000.
P226 Blackwater
ntroduced in 2007, the SIG P226 Blackwater was designed in cooperation with the Blackwater Training Center. It featured SIGLITE front and rear night sights, the Blackwater USA logo on the slide and wood grips, an integral Picatinny rail, black anodized frame, and Nitron-coated stainless steel slide. It was only available in 9x19mm Parabellum, with a double-action/single-action (DA/SA) trigger. The gun was sold with five 15-round 9mm magazines. The P226 Blackwater was discontinued in 2009 with the release of the P226 Blackwater Tactical - a nearly identical pistol also with 20 round 9mm magazines.[8] The Blackwater Tactical has since been discontinued, having been replaced by the Tactical Operations. It is essentially the same weapon, but lacks Blackwater markings.
P226 SCT
The P226 SCT (Super Capacity Tactical) is an all black, Nitron finished P226 featuring front cocking serrations, accessory rail, a SIGLITE rear night sight, a TRUGLO Tritium Fiber Optic front sight and comes with four newly designed 20-round magazines for the 9mm version or four 15-round magazines for the .40S&W version.
P226 Equinox
The P226 Equinox comes chambered in .40 S&W and features a two-tone accented design. The design is achieved by the brush polished flats of the slide and nickel accents of the gun's controls. The P226 Equinox comes with a TRUGLO Tritium Fiber Optic front sight, rear SIGLITE night sights, SIG accessory rail, and gray laminated wood grips.
P226 ST
The SIG Sauer P226 ST was a limited production all-stainless version of the SIG P226 pistol. It is heavier than a standard P226 because the frame was made of stainless steel instead of aluminum. Weight with the magazine was a hefty 42.2oz vs 34oz of the standard aluminum-framed version. The added weight of an all-stainless frame is claimed to provide greater recoil reduction and a quicker return to target between shots making it a common choice among Practical Shooting competitors. The P226 Stainless had a blued barrel and featured an M1913 Picatinny rail. These frames were made in Germany. Prototypes were tested in 2006 and it went into production in very limited numbers. The P226 ST in no longer manufactured.
P226R HSP
On sale 2005-09-11, SIG Sauer Homeland Security Pistols (HSP) are the same models SIG builds for the United States Department of Homeland Security. This is a limited production run of 1,000 P226R HSP pistols available engraved with the American flag and Homeland Security X of 1000. Additionally, each pistol comes in .40 S&W caliber and is engraved with serial number barcoding just like those which were shipped to DHS. The HSP also features the new DAK trigger, a stainless steel Nitron slide topped with SIGLITE night sights, and a light weight alloy frame with rail.
There is also a P229R HSP model available with the same features.
P226 X-Five
The SIG Sauer P226 X-Five is a competition only variant of the P226 with a 5 in (13 cm) slide and barrel, beavertail grip, and an adjustable rear target sight. Intended for IPSC Wa1500, bullseye and other centrefire competitive shooting, the X-Five is hand-fitted and assembled in Germany, and its resulting accuracy accordingly rivals the legendary SIG P210. Available in 9mm or .40 S&W, there are four models being offered in the United States:
* The "Competition" model has a single-action-only (SA) trigger, ambidextrous thumb safety, flared magazine well, and high-capacity magazines (19-round 9mm/ 14-round .40 S&W).
* The "Level-1" model adds a special adjustable SA trigger and Nill wood grips.
* The "Allround" model has a double-action/single-action (DA/SA) trigger, a decocking lever and a standard magazine well designed to accommodate P226 magazines.
* The "Tactical" model comes with a black Ilaflon finish, and features a heavy-weight alloy frame with a SIG rail, and fixed contrast or tritium night sights. Available in either SA or DA/SA configuration. (US models only come chambered for 9mm, but a .40 S&W model is available in Germany.)
All SIG P226 X-Five models include a factory test target with a sub-1 inch 5-shot grouping from 25 metres (82 ft).
