The SIG Sauer P320 COMPACT is a modular striker-fired pistol built for serious shooters who demand adaptability. Its serialized fire control unit allows for quick caliber and grip module swaps, making it a versatile platform for duty, defense, or competition. Since we added it to our lineup in fall 2025, it has consistently ranked among our top-selling handguns in its class, proving its popularity with knowledgeable buyers.
Key Features
- Modular Fire Control Unit (FCU): The serialized chassis is the firearm’s core. Swap grip modules and slides in minutes to change size or caliber.
- Striker-Fired Reliability: Smooth, consistent trigger pull with a short reset for rapid, controlled follow-up shots.
- Optics-Ready Design: The slide is cut from the factory to accept popular micro red dot sights (adapter plates may be required).
- Enhanced Ergonomics: Textured grip module provides a secure hold, and the low bore axis reduces muzzle flip for faster recovery.
- Ambidextrous Controls: Includes a reversible magazine release for left- or right-handed operation.

Frequently Asked Questions
Is the P320 COMPACT optics-ready?
Yes. The slide comes cut from SIG Sauer to accept a variety of micro red dot sights. You may need a specific adapter plate depending on the optic model you choose.
Can I change the grip size?
Absolutely. The modular design means you can purchase different SIG grip modules separately. They snap onto the serialized Fire Control Unit, allowing you to customize fit and size without an FFL transfer.
What’s included in the box?
The pistol comes with one 15-round magazine, a cable lock, and manuals. A note from our staff: The firearm itself is flawless, but the factory box is somewhat flimsy. We handle all shipments with extra care to ensure it arrives securely.
