SIG Sauer is one of the world’s biggest firearms manufacturers for a reason. They produce high quality firearms that have seen service with military, law enforcement, and civilians all over the globe.
From concealed carry pistols to duty sidearms to sniper rifles to submachine guns to assault rifles and so on, SIG manufacturers just about every type of firearms one can imagine.
Originally based out of Germany and Switzerland, SIG has since relocated most of their production over to New Hampshire for the American market. Their dedication to quality, however, has not at all changed (nor has their reputation to innovation either).
Here are the greatest SIG Sauer guns of all time [user voted]:
The SIG Sauer P226 is perhaps SIG’s most famous handgun. This pistol was introduced in the 1980s to compete for the United States army contract as the new service handgun to replace the Colt M1911A1. For context, the P226 is essentially a double stacked P220 rechambered for 9mm. The P226 and Beretta M9 became the final competitors out of an initially much larger field, with Beretta emerging as the victor. However, the P226R was still adopted as the main handgun of the United States Navy SEALs, but it was later replaced by the Glock 19.
Standard capacity of the P226 is 15 rounds, but longer 18 round magazines are being made by Mec Gar. P226 pistols today are still in service with many law enforcement and military units all around the world.
In 2017 the SIG Sauer P320 in 9mm became the new service handgun of the United States military to replace the Beretta M9. The P320 is notable because it’s a truly modular handgun. You can remove the firearm action from the frame and the interchange as appropriate. For example, you can purchase different frame sizes of the P320 and swap the same gun into each giving you both a compact and a mid sized or full sized handgun depending on what you want.
The SIG Sauer P365 represents one of the more innovative concealed carry firearms in several years. The 9mm single stack handgun has served as one of the most popular genres of handguns for the American CCW market. Examples include the Glock 43, Ruger LC9, Smith & Wesson Shield, and the Walther PPS. Each of these pistols are very thin and compact and usually hold only 6-7 rounds in the magazine.
The reason why the P365 is so innovative is because it is of the same approximate height and width as the typical 9mm single stack pistol, and yet has a double stacked magazine with twice the capacity at 10 rounds. The P365 XL is capable of holding 12-15 rounds depending on the magazine. There’s simply no other pistol on the market now that is of the same compact size of the P365 and offering the same level of firepower.
The SIG Sauer P210 was the pistol that started it all. Released in 1948, it was the first major success for SIG Sauer. The P210 is a single action only hammer fired pistol with a single stack magazine that holds 8 rounds of 9mm Luger. The P210 was adopted by numerous European police and military units, and continued to see service until fairly recently. SIG released the P220 in 1975, which largely served as the P210’s successor. The Danish police, for instance, continued to use the P210 up until the 2010s, when it was finally replaced by the SIG Sauer P320.
The P210 ceased production temporarily in 2006, before being revived in 2017 as the P210A, which is essentially the same gun sold as a classic by SIG in limited numbers.
The P228 was originally developed as a more compact version of the P226, and was adopted by the United States army. The P228 later developed into the P229, and the two guns are one and the same only with the P229 slide built out of stainless steel in contrast to the P228’s carbon. This was done so the P229 could handle the higher pressures of the hotter .40 S&W and .357 SIG rounds. The .357 SIG version of the P229 serves as the main sidearm of the United States Secret Service, and earlier the P228 in 9mm served as their main sidearm.
The P228 was technically discontinued, but the same gun in the form of the SIG Sauer M11-A1 is still being made today. For all intents and purposes, the M11 is identical to the original P228, with only the markings being different. The M11-A1 is so named because it was the designation giving to the handgun by the United States military.
The SIG Sauer GSR 1911 is one of the highest selling 1911 pistols in the United States today. The GSR is also widely regarded as being one of the highest quality 1911s on the market, because of its extremely crisp single action trigger and excellent accuracy. SIG claims that the GSR 1911 is capable of producing a 1.5” group at 25 meters. The GSR 1911 is also offered in a variety of finishes, including stainless steel, Nitron dark, or two tone.
The SIG Sauer MPX is a gas operated semi-automatic pistol (or submachine gun for military and law enforcement). It’s very compact and utilizes a closed, rotating bolt that is actually rare in submachine guns but is intended to make the weapon more reliable. The MPX was unveiled in 2015, and later led to the release of the MCX as well.
The P220 was introduced as the first installment in SIG’s 220 line. Initially chambered in both 9mm and .45 ACP, the P220 later switched to being a .45 ACP only handgun, and it is currently only offered in the .45 ACP caliber. The P220 was essentially the successor to the P210. It has a double action single action trigger mode with a decocker lever located on the side of the frame that should be easy for the user’s finger or thumb to reach. Standard magazine capacity is 8 rounds.
The P220 is currently still being made today with improved ergonomics and a tactical rail located on the frame for adding lights and lasers. The old 9mm version is still serving as the main service handgun of the Japanese military.
The SIG Sauer MCX is a semi-automatic rifle similar to the AR-15. It utilizes a short stroke gas piston system that is designed to keep recoil to a minimum and reliability to the maximum. The design is technically based off of the pistol caliber MPX. The MCX is available for the 5.56 and .300 AAC, and is compatible with STANAG magazines. The upper receiver is also compatible with the lower receivers of the AR-15.
The SIG Sauer P225 is scaled down P220 chambered for 9mm with 8 rounds of ammunition in the magazine. The P225 is noticeably more compact than the P220, and was originally developed as the P6 for West German police forces in the 1970s, where it was introduced alongside the Walther P5 and the HK P7. The manual of arms between the P220 and the P225 is exactly the same.
The original version of the P225 was discontinued, but a new version called the P225-A1 was recently released by SIG a few years ago as the original P225’s successor. The new P225-A1 is essentially a single stack version of the P228/P229.
The SIG Sauer P238 is a clone of the Colt Mustang, which itself is basically a pocket carry version of the 1911 and rechambered for the .380 ACP round. The Mustang series of handguns are among the most shootable of the pocket 380s and the P238 is no exception. This pistol was unveiled in 2009 and the P938 came out a few years later. The P238 is one of the highest selling .380 pocket pistols on the marketplace today.
