Are All Sig Sauer P365 Magazines Interchangeable?

Sig Sauer P365 magazines are generally designed to be interchangeable within the P365 series, but there are a few important nuances to consider:

  • Standard P365 vs. P365 XL: The standard Sig Sauer P365 magazines will fit in both the P365 and P365 XL models. However, if you use a standard P365 magazine in a P365 XL, it will sit flush with the grip, as the P365 XL has a slightly longer grip.
  • Base Plates: Some P365 magazines come with different base plates (flat, pinky extension, etc.). These base plates can affect how the magazine sits in the firearm and may impact concealability and comfort.
  • Compatibility with Manual Safety Models: There might be slight differences in magazine fit for P365 models equipped with manual safeties. While the magazines should still function properly, it's always a good idea to check compatibility if you have a manual safety variant.

What Is the Difference Between P320 and P365 Magazines?

The Sig Sauer P320 and P365 magazines are distinct and not interchangeable due to differences in size, capacity, and design. P320 magazines are larger and available in capacities ranging from 10 to 30 rounds, fitting the wider and taller grip frame of the P320 series. In contrast, P365 magazines are slimmer and more compact, with common capacities of 10, 12, and 15 rounds, designed for the P365's smaller frame ideal for concealed carry. The P320 magazines cater to duty and service use, while P365 magazines are tailored for personal defense and ease of concealment. Ensure you select the correct magazine for your specific model to guarantee proper fit and function.
