Home defense requires a platform that balances accuracy, capacity, and intuitive controls under stress. An owner needs a pistol that is reliable straight out of the box, easy to manipulate for all shooters, and adaptable to changing needs—whether outfitted with a light or moved between grip modules.

SIG SAUER P320 is a full-size, modular, striker-fired pistol built around a 4.7-inch barrel and a polymer medium grip module that prioritizes accuracy and controllability for defensive and range work.

Design and modularity that matter

The SIG SAUER P320’s modular fire control unit allows the entire serialized chassis to move between slides and grip modules without gunsmithing. That system supports different hand sizes or mission profiles without buying a separate serialized firearm. Tool-free 3-point takedown speeds maintenance and reduces takedown errors during routine cleaning.

Ergonomics and controls

The full-length slide includes front and rear serrations for positive manipulation. The medium polymer grip sits well for most shooters and the ambidextrous slide stop with reversible controls accommodates left-handed users. A Picatinny accessory rail accepts lights or lasers for low-light home defense setups.

Trigger, safeties, and sights

The SIG SAUER P320 is striker-fired with a smooth, crisp trigger and a short reset that supports quick follow-up shots. It does not include a manual thumb safety but incorporates internal safeties—a striker safety and a disconnect safety—helping prevent accidental discharge from drops or manipulations. SIGlite front and rear night sights offer real-world visibility in low-light defense scenarios.

Caliber and capacity

Chambered in 9mm, the P320 balances recoil management, magazine capacity, and ammunition availability—making it a sensible choice for home defense and range practice. Standard capacity is 17 rounds (some configurations are limited to 10 rounds where required), providing extended capability without excessive reload frequency.
