Sig Sauer P320

The Sig Sauer P320 is a pistol that has been tested and abused over many years, and has never disappointed. Now it is regularly at the side of active military members, law enforcement, concealed carriers, and everyday gun enthusiasts. That fact is simply due to the P320’s modularity, incredible accuracy, and unyielding reliability.
The Sig Sauer P320 gives any pistol a run for its money in terms of performance and reliability. For that reason, the P320 is one of the most sought after pistols on the market. If you see one in your local gun store, it likely will not be there long.
Safety Without Compromise
It does not matter how smooth a pistol shoots, or how nice it looks if it is not safe to shoot and carry. Sig Sauer is never willing to sacrifice safety for performance with the P320.The P320’s safety system is one of the best on the market.
For starters, the P320 is striker fired and has a disconnect safety. Then it has a three point take down safety system, which allows you to disassemble your pistol without pulling the trigger. Certain models, like the M17 and M18, have manual safeties in addition to the already rigorous P320 safety system.

Sig Sauer P320 Models & Variations
The modular design of the P320 comes from the fact that Sig Sauer wants this pistol to fit the needs of absolutely any user. You can find a P320 for just about every use, and if you cannot find what you want, they will sell you their Fire Control Unit, and you can build your own P320 around it. You can get a P320 in a few calibers, 9×19mm Parabellum .357 SIG .40 S&W, 10mm Auto and .45 ACP; however, 9mm is the most common.

Sig Sauer P320 M17

This firearm went under the most rigorous inspections and tests available before it was adopted into the United States Military. It was selected for service because of its modularity, incredible performance, and capability to perform in any situation. So far, the Sig Sauer P320 M17 has not disappointed, and has been at the side of thousands of courageous soldiers.
Unlike most P320 models, the M17 has an ambidextrous manual safety. Many shooters prefer to have a manual safety. So much so that other models of the P320 have been outfitted with a manual safety just to meet customer demand. However, if you want a full-size pistol, and prefer or don't mind a manual safety, the M17 is the way to go. Plus, you can have up to 21 rounds in a standard magazine.

Sig Sauer P320 XFive Legion

The first thing you will say when you pick up a Sig Sauer P320 XFive Legion is “wow that's a heavy pistol!”, and that is all by design. This P320 variant is a 9mm, and out of a 43.5 oz pistol, you are going to get very little recoil. Although the strategy is not to just make this pistol as heavy as possible, the top of the slide is milled out to lower the pistol's center of gravity which reduces muzzle flip.
The TXG tungsten-infused grip helps add the weight of metal, while keeping the flexibility of polymer. This grip module, along with the special slide, is responsible for a 50% reduction in muzzle flip from the standard P320! The recoil system as a whole also received a hefty upgrade thanks to a solid steel guide rod, and a much stronger spring.
You will also experience a 30% lighter trigger pull thanks to the smooth trigger system and new skeletonized trigger. There was a lot of thought that went into this design, and it is no surprise that it won “Handgun of The Year” in 2020 from the Industry Choice Awards.

Sig Sauer P320 Spectre Comp

The Sig Sauer P320 Specter Comp is at the forefront of performance, looks, and functionality. It can do every job out there, from winning a competition, being your everyday carry, your nightstand home defense, or the nicest gun at the range. The custom designed compensator heavily reduces muzzle flip, and the TXG tungsten-infused grip module makes this pistol even easier to control.
The latest pistol in the spectre lineup features a redesigned slide with falling serrations and an optic plate cover. This makes it compatible with all of the most popular red dot sights, however, it still comes with X-Ray3 Night Sights. The trigger on this pistol is exceptional, and the design as a whole produces an incredibly capable firearm.

Sig Sauer P320 XCarry Legion

The Sig Sauer P320 XCarry Legion is yet another very capable P320 variant. This pistol is a perfect balance between performance and practicality. The XCarry Legion is big enough to be a workhorse, but still small enough to carry everyday if you wanted to. The TXG XCarry grip module adds enough weight to this pistol to reduce the muzzle flip by 50% when compared to similarly sized guns.
Thanks to its skeletonized trigger, smooth Fire Control Unit, and 30% lighter recoil, the XCarry Legion is a smooth shooter. Your 4.6 inch threaded barrel can also accept a suppressor if you wanted to add one. Between the barrel, grip module, skeleton trigger, XRay 3 sights, and extended magwell, this pistol does not just look good, it performs like no other.
