P320 vs. P365 | SIG Sauer’s Pistols Head-to-Head

When it comes to SIG Sauer, one of the most reputable names in the firearms industry, two of their most popular pistol models stand out: the SIG P320 and the SIG P365. Both are widely respected for their reliability, accuracy, and innovative features. But which one is better for your specific needs? Whether you're a concealed carrier, competitive shooter, or a gun enthusiast, understanding the strengths and differences between these two models can help you make an informed decision. In this article, we'll compare the P320 and P365 in detail, highlighting key factors like size, capacity, versatility, and price.

1. Overview: SIG P320 and P365

The SIG P320 and P365 are part of SIG Sauer's extensive pistol lineup, each targeting slightly different users and applications.

• SIG P320: This is a modular, striker-fired pistol that has gained a large following, especially after it was selected as the U.S. Army's official sidearm under the designation M17. The P320 is known for its adaptability, with numerous grip and slide options, making it highly customizable.
• SIG P365: Launched as a game-changer in the world of concealed carry pistols, the P365 has a compact size but boasts an impressive capacity, offering a balance between size and firepower that made it an instant favorite among concealed carriers.

Let’s break down the specific characteristics of each pistol to help you determine which best suits your needs.

2. Size and Dimensions: Concealment vs. Full-Sized Power

When choosing between the P320 and P365, size is one of the most critical factors, especially if you’re considering concealed carry.

• SIG P320 Size: The P320 is a larger pistol and comes in various sizes, including Full-Size, Carry, Compact, and Subcompact models. For example, the P320 Compact has a barrel length of 3.9 inches, an overall length of 7.2 inches, and weighs around 25.8 ounces. While its size may make it less ideal for deep concealment, its larger frame offers more comfort and control when shooting, especially for those with bigger hands.
• SIG P365 Size: The P365 was designed with concealment in mind. Its barrel length is only 3.1 inches, and the overall length is just 5.8 inches, making it significantly smaller than the P320. It weighs only 17.8 ounces, making it easier to carry for extended periods. Its slim profile (1.06 inches wide) also makes it a favorite for appendix or pocket carry. Despite its smaller size, the P365 doesn’t compromise on firepower (as we’ll discuss in the next section).

Winner: The P365 takes the edge for concealed carry due to its compact size, though the P320’s larger size could be preferable for those wanting a more traditional full-sized pistol feel.

3. Capacity: Big Firepower in Small Packages

Capacity is a major consideration when choosing a handgun, especially for self-defense or competition.

• SIG P320 Capacity: The P320 offers a range of capacities depending on the model and magazine used. The P320 Full-Size typically holds 17 rounds in a 9mm configuration, while the Compact version holds 15 rounds. You can also use extended magazines to increase the round count.
• SIG P365 Capacity: Despite its smaller frame, the P365 was revolutionary for offering a high capacity in a micro-compact design. The standard P365 ships with 10-round flush-fit magazines, but 12-round and even 15-round extended magazines are available. The P365 XL, a slightly larger variant, comes standard with a 12-round magazine.

Winner: The P320 offers higher capacity overall, but the P365’s ability to pack up to 15 rounds in such a small package is impressive. If capacity in a compact frame is essential, the P365 is your choice.

4. Trigger: Performance and Feel

The trigger can make a significant difference in the shooting experience.

• SIG P320 Trigger: The P320 features a smooth, crisp, striker-fired trigger. The modular trigger group in the P320 can be swapped into different frame sizes and configurations, allowing you to change the trigger’s feel or style. The trigger pull weight is around 6 pounds, making it heavier than some competition guns but manageable for a duty or self-defense gun. The P320 X-Five model features a flat-faced trigger, designed for competition shooting and faster reset.
• SIG P365 Trigger: The P365’s trigger is also striker-fired and has been widely praised for its smoothness and reliability. The pull weight is around 6 pounds, similar to the P320, but it is designed for a shorter reset, which can make follow-up shots faster and more accurate. The P365 XL also offers a flat-faced trigger similar to the P320 X-Five, which is another option for those who prefer this style.

Winner: Both pistols feature excellent triggers, but the P320’s modular design allows for more customization options.

5. Modularity: Customization and Versatility

One of the standout features of the SIG P320 is its modularity.

• SIG P320 Modularity: The P320 is built on a modular chassis system, meaning the internal fire control group can be moved between different grip modules, slide lengths, and calibers. Whether you want to change your P320 from a compact carry pistol to a full-sized competition gun, the P320 makes it easy. This adaptability is why it’s become a favorite among professional users, including the military and law enforcement.
• SIG P365 Modularity: While not as modular as the P320, the P365 has some customization options. The P365 XL model offers a longer slide and barrel for improved accuracy, and various grip and trigger upgrades are available in the aftermarket.

Winner: The P320 dominates in terms of modularity and customization. If you’re looking for a pistol that can evolve with your needs, the P320 is the better option.

6. Recoil and Shootability

Recoil control can determine how quickly you can get back on target and fire follow-up shots.

• SIG P320 Recoil: Thanks to its larger size and weight, the P320 handles recoil better than smaller pistols. This makes it easier to control and shoot, especially during rapid fire or in high-stress situations. The P320 X-Carry and P320 X-Five models, in particular, are designed for superior shootability and recoil control.
• SIG P365 Recoil: The P365, while designed for concealment, does a decent job at managing recoil. However, due to its smaller and lighter frame, it’s not as easy to control as the P320. The slightly larger P365 XL improves shootability with its longer barrel and grip, offering better recoil control compared to the original P365.

Winner: The P320, especially in its larger models, offers superior recoil management and is more enjoyable to shoot over long sessions. For concealed carry purposes, though, the P365 is more than manageable for most shooters.

7. Price: Budget Considerations

Both pistols are competitively priced within their respective categories, but their prices vary depending on the specific model and configuration.

• SIG P320 Price: The price for a standard P320 ranges between $550 and $700, with more premium models like the P320 X-Five or P320 Legion reaching upwards of $1,000. The P320 offers great value for a duty or full-sized pistol with high-quality features.
• SIG P365 Price: The P365 typically retails between $500 and $600, with the P365 XL and P365 SAS versions priced slightly higher. Even with its compact size, the P365 delivers excellent value for money with its high capacity and performance in a small package.

Winner: The P365 offers slightly more affordability, especially when considering it is designed primarily for concealed carry. However, the P320 offers tremendous value for shooters who want a versatile, modular pistol.

Conclusion: Which One Is Right for You?

Ultimately, the decision between the SIG P320 and P365 comes down to your specific needs. If you’re looking for a highly customizable pistol with greater shootability, the P320 is hard to beat. Its modularity, recoil control, and variety of models make it a versatile option for both beginners and seasoned shooters alike.

On the other hand, if you prioritize concealed carry, the P365 is a standout performer in a small package. With its impressive capacity, compact size, and shootability, it’s ideal for daily carry or those looking for an effective self-defense pistol.

Whether you opt for the P320 or P365, you’ll be getting a high-quality firearm backed by SIG Sauer’s reputation for excellence.
