Sig Sauer P320 vs P365: Comprehensive Guide for Red Dot Sight Selection

Sig Sauer P320 and Sig Sauer P365 are two highly popular handguns produced by SIG Sauer, each with their unique features and uses. When comparing these two firearms, especially considering the choice of red dot sights, here are some key differences and considerations:

Size and Weight:

• P320: Larger and heavier, available in various sizes (full-size, compact, and sub-compact). Suitable for law enforcement, sport shooting, or as a service weapon.
• P365: Smaller and lighter, a pocket-sized handgun, very suitable for concealed carry.

Magazine Capacity:

• P320: Offers multiple caliber options, including 9mm, .357 SIG, .40 S&W, and .45 ACP. Magazine capacity varies depending on the model and caliber, generally larger than the P365.
• P365: Provides an impressive magazine capacity for its small size (up to 15 rounds in 9mm).

Usage:

• P320: Due to its size and customizability, suitable for various purposes, including home defense, law enforcement, and competitive shooting.
• P365: Mainly used for concealed carry and personal defense.

Red Dot Sight Selection:

Compatibility: When choosing a red dot sight, first ensure it is compatible with your handgun model.

Size: For a small handgun like the P365, choosing a compact and lightweight red dot sight is more appropriate to avoid adding too much weight or bulk. The RMSc footprint sights, such as the Shield RMSc, and Foxarmy FXV22RPO, are usually a good choice.

For the full-size P320, sights with an RMR footprint, like the Trijicon RMR, are suitable.

Mounting Method: Ensure the red dot sight's mounting method is compatible with your handgun. For example, the P320 and P365 might require different types of mounting interfaces.

Durability and Performance: Considering different usage environments, choose a durable and reliable red dot sight.

Budget: High-quality red dot sights are usually more expensive; choose a product that fits your budget.

Modularity and Customizability:

• P320: Highly modular, users can replace the barrel, grip module, and slide.
• P365: Although not as modular as the P320, it still offers some level of customizability.

In conclusion, when choosing a red dot sight, considering the size and use of the handgun, as well as personal habits and needs, is crucial. Although both the P320 and P365 are excellent firearms, their design and purpose differ, which also affects the choice of appropriate red dot sights for them.
