The SIG Sauer P320 and M18 are both popular striker-fired pistols known for their reliability and modularity. Both are excellent choices for concealed carry, but which one reigns supreme? This in-depth comparison will delve into the key differences between the SIG Sauer P320 Compact and the M18, helping you decide which pistol best fits your needs. We'll examine factors like size, weight, capacity, features, and overall suitability for concealed carry.
Key Differences: P320 Compact vs. M18
The SIG P320 Compact and the M18 share a common ancestor, but distinct design choices make them tailored for different users. The core difference lies in their intended roles: the P320 Compact prioritizes size for everyday carry, while the M18 is a military-spec design, slightly larger but with enhanced features for professional use. Let's break down the critical distinctions:
Size and Weight: A Compact Carry Consideration
| Feature | P320 Compact | M18 |
|---|---|---|
| Overall Length | ~6.6 inches | ~7 inches |
| Height | ~4.6 inches | ~5.3 inches |
| Width | ~1.2 inches | ~1.3 inches |
| Weight (empty) | ~24 ounces (depending on model) | ~26 ounces (depending on model) |
As the table shows, the P320 Compact is noticeably smaller and lighter. This makes it more comfortable for concealed carry, especially for individuals with smaller hands or those who prefer a lighter setup. The M18, while still manageable for concealed carry, has a slightly larger grip and overall dimensions, making it less easily concealed for some users.
Capacity: Rounds in the Magazine
Magazine capacity varies depending on the state and the specific magazine used. However, generally:
- P320 Compact: Typically holds 12+1 rounds (15+1 is available with extended mags)
- M18: Typically holds 17+1 rounds (the standard for a military pistol)
The increased capacity of the M18 is a significant advantage for those prioritizing maximum firepower. However, this comes at the expense of a larger profile that makes it less easily concealed for many users.
Features: Military Grade vs. Everyday Carry
The M18 incorporates several features geared towards military and law enforcement use:
- Nitron Finish: Enhanced corrosion resistance for harsh environments.
- Enhanced Trigger: Often featuring a slightly different trigger pull than the P320 Compact, optimized for consistent performance under pressure.
- MIL-SPEC Features: It meets stringent military specifications for durability and reliability.
The P320 Compact, while highly reliable, generally features a standard trigger and finish, focusing on practicality and ease of concealed carry.
Trigger and Ergonomics: A Matter of Preference
Both pistols utilize SIG's striker-fired mechanism. While both trigger pulls are generally considered smooth, there are subtle differences in feel and weight, largely due to manufacturing and user modifications. The ergonomics of both pistols are generally well-regarded. However, users with smaller hands might find the P320 Compact's slightly smaller grip more comfortable.
Accuracy and Reliability: Both Perform Exceedingly Well
Both the P320 Compact and the M18 are known for their accuracy and reliability. Both pistols are consistently praised for their performance, with many users reporting few issues with malfunctions. The accuracy of each will vary based on the user’s skill, ammunition used, and proper maintenance.
Price: A Factor to Consider
The pricing on both pistols can fluctuate depending on retailer, model, and specific accessories. In general, expect to see some price variation between the two models, with the P320 Compact often being slightly more budget-friendly.
Which Pistol is Right for You?
The choice between the SIG P320 Compact and the M18 hinges on your individual needs and preferences.
-
Choose the P320 Compact if: You prioritize concealability and a lighter carry setup for everyday use. A smaller frame is crucial to you, and you may be more comfortable with a slightly smaller magazine capacity.
-
Choose the M18 if: You need maximum capacity and the enhanced features of a military-grade pistol. A larger, more robust pistol is acceptable, and perhaps preferred.
Ultimately, the best way to decide is to handle both pistols if possible. Visit a local gun store and try them out to see which feels more comfortable and natural in your hand. Consider your individual needs and preferences, ensuring the pistol is a safe and comfortable fit for your specific application. Remember to always practice safe gun handling and abide by all applicable laws and regulations.
