Detailed Comparison: Sig 320 vs 365

Let’s delve into a detailed comparison of the Sig 320 vs 365 across various categories:

Size and Dimensions

The most significant difference between the Sig 320 and Sig 365 is their size. The P365 is significantly smaller and lighter, making it ideal for concealed carry. The P320, particularly in its full-size and compact variants, is larger and heavier, better suited for open carry, duty use, or home defense.

Here’s a general comparison:

• P320 (Compact): Approximately 7.2 inches in length, 5.3 inches in height, and 1.3 inches in width.
• P365: Approximately 5.8 inches in length, 4.3 inches in height, and 1.06 inches in width.

The P365‘s smaller dimensions make a noticeable difference in concealability, especially for those with smaller frames or those who prefer to carry inside the waistband (IWB).

Capacity

While the P365 is smaller, it boasts an impressive capacity for its size. Standard magazines hold 10 rounds, with extended magazines available for 12 or 15 rounds. The P320, depending on the variant, typically holds 17 rounds in its full-size configuration, with options for higher-capacity magazines.

• P320 (Compact): 15 or 17 rounds (depending on magazine).
• P365: 10, 12, or 15 rounds.

If capacity is a primary concern, the P320 generally offers more rounds, but the P365 provides a respectable capacity in a much smaller package.

Ergonomics and Handling

Both the Sig 320 and Sig 365 are known for their comfortable ergonomics, but they cater to different preferences. The P320‘s modular grip allows users to customize the grip size to fit their hand perfectly. The P365, despite its smaller size, features a well-designed grip that provides a secure and comfortable hold for most shooters. Many find the Sig 365 surprisingly comfortable to shoot, even with larger hands. However, some may prefer the more substantial feel of the Sig 320.

Trigger Performance

Both pistols feature striker-fired triggers, but their feel and performance differ slightly. The P320 is known for its smooth, consistent trigger pull with a clean break. The P365 also has a crisp trigger, but some users find it slightly heavier than the P320‘s trigger. However, both triggers are generally considered to be excellent for defensive pistols.

Accuracy

Accuracy is subjective and depends on the shooter’s skill, but both the Sig 320 and Sig 365 are capable of excellent accuracy. The P320, with its longer barrel and sight radius, may offer a slight advantage in accuracy, particularly at longer distances. However, the P365 is surprisingly accurate for its size, and many shooters can achieve tight groupings with practice. Ultimately, the difference in accuracy is often negligible for most practical purposes.

Modularity and Customization

The Sig 320‘s modularity is a major selling point. The FCU allows users to swap out the frame, slide, and barrel to create different configurations, such as changing the size, caliber, or adding aftermarket parts. The P365 is less modular, but it still offers some customization options, such as different grip modules and aftermarket triggers. If modularity is a priority, the P320 is the clear winner.
