The SIG Sauer P320 is a modular handgun platform known for its versatility and reliability. A key decision for potential buyers is choosing between the compact and full-size models. This in-depth comparison will help you understand the key differences and determine which P320 is the best fit for your needs and shooting style.
Size and Weight: The Most Obvious Difference
The most striking difference between the SIG P320 Compact and Full Size lies in their dimensions and weight. The Full Size model offers a longer barrel and slide, resulting in greater accuracy potential and a slightly flatter shooting experience due to the longer sight radius. This also translates to a higher capacity magazine. However, this comes at the cost of increased size and weight, making it less concealable and potentially more cumbersome for extended carry.
The Compact model, on the other hand, is noticeably smaller and lighter, making it far more suitable for concealed carry. Its reduced size makes it easier to maneuver and handle, particularly for individuals with smaller hands. While it offers a shorter barrel and sight radius than its full-size counterpart, it still delivers reliable performance.
| Feature | SIG P320 Compact | SIG P320 Full Size |
|---|---|---|
| Barrel Length | Typically 3.9 inches | Typically 4.7 inches |
| Overall Length | Approximately 6.8 inches | Approximately 7.2 inches |
| Weight (unloaded) | Approximately 24 ounces | Approximately 29 ounces |
| Magazine Capacity | Varies by model and state laws | Varies by model and state laws |
Capacity and Caliber Options
Both the Compact and Full Size P320s are available in a variety of calibers, including 9mm, .40 S&W, and .357 SIG. However, the magazine capacity will differ. The Full Size typically holds more rounds per magazine compared to the Compact. The exact capacity will depend on the specific model and any applicable state restrictions on magazine capacity.
Always check your local and state laws regarding magazine capacity before purchasing.
Concealability and Carry
The Compact's smaller size and lighter weight make it a much more practical choice for concealed carry. Its slim profile allows for easier concealment under clothing, making it a top choice for everyday carry (EDC).
The Full Size is less ideal for concealed carry due to its larger dimensions. While it's not impossible to conceal, it will be more challenging and less comfortable for extended periods. It's better suited for home defense or range use.
Accuracy and Shooting Experience
While the Full Size's longer barrel and sight radius contribute to improved accuracy potential, the difference isn't always significant for the average shooter. Both models provide reliable accuracy, suitable for self-defense and target shooting. The longer sight radius on the Full Size simply gives a slight edge in precision shooting at longer ranges. The Compact's shorter sight radius might require a bit more practice for consistent accuracy at greater distances.
Ergonomics and Handling
Both the Compact and Full Size versions maintain the same ergonomic design elements that the P320 platform is known for. However, hand size plays a crucial role in determining which model feels better. Shooters with smaller hands might find the Compact easier to grip and control, while those with larger hands might prefer the Full Size's more substantial grip.
The Verdict: Which P320 is Right for You?
The best choice between the SIG P320 Compact and Full Size ultimately depends on your individual needs and priorities.
-
Choose the Compact if: You prioritize concealability, lighter weight, and ease of carry for everyday situations.
-
Choose the Full Size if: You prioritize maximum capacity, potentially higher accuracy at longer ranges, and a more substantial feel in the hand. Home defense is a primary use case.
Consider handling both models at a gun range or store to see which feels more comfortable and fits your hand size and shooting style before making your final decision. Remember to always prioritize safety and follow all firearm safety regulations.
