What Sets the SIG SAUER P320 Nitron Carry Apart

1. Modular Fire Control Unit (FCU)

At the core of the P320 Nitron Carry is its revolutionary serialized FCU—a stainless steel chassis that is the legally recognized “firearm.” This core component can be swapped into different grip modules and slide assemblies to create the exact configuration you want.

Unlike traditional handguns, which are locked into one design, the P320 empowers users to switch between full-size, carry, compact, and subcompact layouts. The FCU is fully removable, allowing you to clean or customize your weapon without altering serialized parts.

2. Nitron Finish for Durability

The slide’s Nitron finish is more than just aesthetics—it’s a shield. This black nitride coating protects the stainless steel slide against rust, moisture, and scratches. Whether you’re using your pistol in the rain, storing it in a humid safe, or carrying daily, the finish ensures long-term durability and performance.

3. SIGLITE Night Sights for 24/7 Target Acquisition

In low-light conditions, visibility can mean the difference between success and failure. The SIGLITE tritium night sights on the P320 Nitron Carry are factory-installed and designed for rapid target acquisition even in the darkest environments.

Tritium dots glow softly in darkness without needing an external power source, providing a reliable sight picture during emergencies, home defense scenarios, or nighttime carry.

---

4. Carry Frame Configuration: Balance of Control and Concealability

The P320 Carry offers a unique frame setup: it combines a compact slide (3.9”) with a full-size grip. This delivers an optimal blend of comfort and concealability:

• Compact slide: Shorter barrel makes the pistol easier to conceal and faster to draw.

• Full-size grip: More surface area to grip, resulting in better recoil management and 17-round capacity.

This hybrid design is especially favored by those who need a dependable concealed carry option without compromising firepower.

5. Smooth, Consistent Trigger Pull

The striker-fired system produces a clean and consistent trigger pull, often compared to that of more expensive target pistols. It offers a crisp break and a short reset, allowing faster follow-up shots and greater accuracy. The trigger pull weight is around 6.5 pounds, striking a balance between performance and safety.

---

6. Internal Safety Systems

Although this model does not feature a manual thumb safety, it includes three key internal safety systems:

• Striker safety

• Disconnect safety

• Optional manual safety (available in other configurations)

These layers of protection prevent accidental discharge, making the P320 Nitron Carry a secure option for concealed carry and home defense.
