Identifying Your SIG Sauer P320: A Comprehensive Guide
So, you own a SIG Sauer P320, but aren't quite sure which exact model you have? This is a common issue, as the P320 platform boasts a huge amount of customization and variation. This guide will help you pinpoint your specific P320 model through a systematic approach. We'll cover key identifying features, common variations, and resources to further assist your identification.
Key Areas for Identification
To accurately identify your SIG P320, meticulously examine these key areas:
-
Caliber: This is arguably the most important identifying factor. Check the barrel and slide for caliber markings (e.g., 9mm, .40 S&W, .357 SIG, 10mm). This is usually clearly stamped.
-
Frame Size: The P320 comes in several frame sizes, impacting the overall size and feel of the pistol. Common sizes include:
- Full Size: Largest frame, offering maximum capacity and stability.
- Carry Size: A more compact option suitable for concealed carry.
- Compact: Smaller than the Carry Size, ideal for deep concealment.
- Subcompact: The smallest frame, prioritizing concealability above all else.
-
Slide Length: Related to the frame size, the slide length can vary significantly. Measure your slide's length for more precise identification.
-
Barrel Length: This measurement is crucial and often varies between models within the same frame size. Check the barrel directly for the length marking, which usually indicates the barrel's length in inches (e.g., 3.9", 4.7").
-
Serial Number: Located on the frame, the serial number can be used to trace your firearm's history through SIG Sauer's website (though they may not disclose specific model details from the serial alone).
-
Markings and Features: Pay close attention to any additional markings on the slide, frame, or other components. These could indicate specific features or model variations (e.g., X-Carry, X-Compact, M17, M18). Look for engravings, logos, and any other unique identifiers.
Common SIG P320 Variations
The SIG P320 platform's modularity leads to numerous variations. Some of the most prevalent include:
-
P320 M17/M18: These are military-inspired models, differing slightly in size and features from the standard P320.
-
P320 X-Series: This series emphasizes performance and customization, often featuring upgraded triggers, slides, and other components. Sub-models within this series include X-Carry, X-Compact, X-Full, etc.
-
P320 AXG: This model features a heavier, more robust frame, usually made from aluminum.
-
P320 Legion: This high-end series boasts upgraded parts and premium finishes.
Further Resources for Identification
-
SIG Sauer Website: While they might not offer definitive identification from a serial number alone, the SIG Sauer website provides a detailed overview of the various P320 models. Comparing your firearm's features to their specifications is a helpful step.
-
Firearm Forums and Communities: Engaging with online communities dedicated to firearms can be beneficial. Posting pictures of your P320 and describing its features often leads to quick and accurate identification from experienced users.
-
Local Gun Shop: A trusted local gun shop is another valuable resource. They are likely familiar with the various P320 models and can help you identify yours based on a visual inspection.
By carefully examining the details outlined above and utilizing available resources, you should be able to successfully identify your specific SIG P320 model. Remember, always handle firearms safely and responsibly.
