Introduction
The Sig Sauer P320, often referred to as the Sig P320, is a semi-automatic pistol popular with security forces and civilian shooters alike. What makes this model unique is its modular design: it can be easily modified to change size, caliber and shape as required. The Sig P320 thus enables users to adapt the weapon to different situations, which is rare for a pistol.
Since its release in 2014, the Sig P320 has grown in popularity, to the point of becoming the US Army’s service weapon in 2017 under the names M17 and M18. In this article, we’ll look at why the Sig Sauer P320 is so popular, its technical features, and the different versions available.
History of the Sig Sauer P320
The Sig Sauer P320 was launched in 2014 by weapons manufacturer Sig Sauer. At the time, Sig Sauer designers wanted to create a pistol that could be easily transformed to meet the varied needs of security forces and civilian shooters. So they created a pistol with a central part (called the Fire Control Unit or FCU) that could be moved into other types of frame to change the weapon’s size and caliber.
This pistol quickly became popular, and in 2017, the US Army chose the P320 to replace the Beretta M9 as its official sidearm. Army models are known as the M17 (standard size) and M18 (compact size). This adoption by the army has reinforced the Sig Sauer P320’s reputation as a reliable and practical weapon.
Sig Sauer P320 Technical Specifications
The Sig Sauer P320 is appreciated for its modularity, ease of use and easy maintenance. Unlike other pistols, which are manufactured in a single size and caliber, the Sig P320 makes it easy to switch from one format to another simply by changing certain parts.
Main specifications :
– Calibers available: 9 mm, .40 S&W, .357 SIG, .45 ACP
– Magazine capacity: varies from 10 to 17 cartridges depending on caliber and model size
– Firing mechanism: with firing pin, for a smoother, easier-to-use trigger
– Safety: several internal safety devices, no external manual safety device by default
– Modularity: the internal chassis (FCU) can be moved to different frames to modify size or caliber
This modularity makes the Sig P320 highly adaptable. For example, someone who owns a Sig P320 can use it for sport shooting with a large size, then convert it to a compact version for concealed carry, all without buying a new pistol.
The Sig P320’s trigger system is also one of its strong points. The trigger is smooth and offers a short reset, enabling fast, accurate shooting.
Sig P320 versions
The Sig Sauer P320 is available in several versions, to meet the needs of every user. These different sizes and configurations enable the P320 to be adapted to both security forces and civilians.
Sig Sauer P320 Full-Size
The Full-Size version is the standard model of the Sig P320, featuring a 4.7-inch barrel for good stability when firing. With its size, this version is mainly used by law enforcement agencies, as it offers a larger magazine capacity and is easy to control when firing rapidly.
Sig Sauer P320 Compact
The P320 Compact is smaller and lighter than the Full-Size version. This model is designed to be easily concealed, making it an excellent choice for personal defense or plainclothes policing. Thanks to its reduced size, it’s easier to carry, while remaining accurate and stable.
Sig Sauer P320 X-Carry and X-Five
The X-Carry and X-Five versions are designed for sport shooting. The X-Carry is an intermediate model, lighter than the Full-Size, but offering good grip and large capacity. The P320 X-Five, on the other hand, is the sporting version with a longer barrel and high-quality components to optimize stability and accuracy during competitions.
Sig Sauer M17 and M18
The M17 and M18 models are the military versions of the Sig P320, chosen by the US Army. The M17 is the standard version, while the M18 is more compact. These models are built to meet military requirements, with special coatings to withstand extreme conditions.
Advantages of the Sig Sauer P320
The Sig Sauer P320 is a pistol that offers many advantages:
1. Modularité : Its ability to change size and caliber makes it unique. With a Sig P320, users can adapt their pistol without buying a new gun, which is both economical and practical.
2. Safety: Even without manual safety, the Sig P320 is designed to be safe thanks to its internal safety features. This makes it easy to use yet reliable.

4. Reliability and precision: Sig Sauer’s manufacturing quality ensures that the P320 performs well, even in difficult conditions. Its smooth trigger and short reset enable fast, accurate shooting, appreciated by professionals and sport shooters alike.
Comparison with other semi-automatic pistols
The Sig P320 is often compared to competing models, including the Glock 19 and Smith & Wesson M&P. Here are a few differences:
– Glock 19: The Glock 19 is known for its reliability and simplicity, but it does not offer the same modularity as the Sig P320. The Glock remains in a fixed configuration, whereas the P320 can easily change size or caliber.
– Smith & Wesson M& P: This model also has good ergonomics, but doesn’t offer the same flexibility as the Sig P320. The M&P can’t be as easily modified to change size or caliber.
– Beretta M9: The US army’s old pistol, the Beretta M9, is heavier and less adaptable than the Sig P320, which is why the army chose the P320 as its replacement. The P320 is more modern and offers more customization possibilities.
These comparisons show that the Sig P320 is a unique choice thanks to its modularity and its ability to meet the specific needs of each user.

Thanks to its different versions, it can be adapted to the needs of sport shooters, police officers, soldiers and civilians.
