Detailed Features 

The P320 platform uses SIG's modular fire control unit, which means the serialized chassis can be swapped between different grip modules, slides, and calibers without additional paperwork. At 3.9 inches the barrel sits between a full-size and a subcompact, giving a workable balance of velocity and concealability. The striker-fired action runs without an external safety lever. At 1.6 lbs it is light enough for all-day carry. 
 

Usage 

The Carry configuration is a natural fit for concealed carry given its size and weight. It also works well at the range and in practical shooting competitions where 9mm capacity matters. The modular grip system lets you fit the gun to your hand size without buying a new pistol.

Positive Sentiments

1. Modularity: Owners consistently cite the modular design as the standout feature. Being able to swap grip modules, slides, and calibers without additional transfers is a practical advantage that few competing pistols offer.

2. Ergonomics: The grip shape gets frequent positive mentions. Most shooters find it comfortable for extended sessions, and the texturing aids control without being abrasive.

3. Trigger: The trigger pull is described as smooth and consistent, with a clean break. This comes up regularly as a reason owners prefer it over other striker-fired options.

4. Reliability: Most owners report solid reliability across a range of 9mm ammunition without meaningful malfunction issues.

5. Size and Weight: The Carry size hits a practical middle ground for those who want something smaller than a full-size but with more barrel than a subcompact. The 1.6 lb weight is frequently noted as a plus for carry.

Critical Feedback

1. No External Safety: The absence of an external safety lever is a polarizing point. Some shooters, particularly those transitioning from manual-safety pistols, find this a concern for everyday carry.

2. Trigger Reset: A minority of users feel the trigger reset is less tactile than they would prefer, especially compared to pistols with more pronounced reset feedback.

3. Price: Some buyers find the P320 priced above comparable striker-fired options, though most who purchase it feel the build quality justifies the cost.

4. Aesthetics: Preference for the P320's utilitarian look versus more traditional pistol profiles is personal. It comes up occasionally but is rarely a deciding factor for most buyers.
