About the Sig Sauer P320
The Sig Sauer® P320 is an ambidextrous and modular striker-fired centerfire pistol, specifically engineered for civilian target shooters, personal defense shooters, and law enforcement agencies across the United States and abroad. Available in 9mm, .40 S&W, and .45 ACP, the P320 features enhanced ergonomics and ambidextrous fire controls for improved comfort and control with either hand, while the striker-fired trigger system offers a consistent pull and crisp break for enhanced accuracy and speedy follow-up shots in virtually any target or tactical shooting scenario.

Modularity and Conversion
The P320 boasts a serialized internal stainless steel frame fire control unit, designed to deliver quick installation with interchangeable grip modules for versatile field service and adaptability.

Additionally, the P320 is easily converted using a variety of factory and aftermarket drop-in conversion kits, allowing you to convert your 9mm pistol to a rimfire .22LR pistol, a.40 S&W, or .45 ACP and back again — without altering your pistol or forfeiting reliability.

What is a striker-fired fire system?
Striker-fired pistols are simple in their operation because after the shooter manually racks the slide to chamber a round, each trigger pull fires a single round, ejects the spent casing, loads another round into the chamber, and rearms the firing pin, all in less than one second. Because there is no hammer to cock or release, the trigger pull of most striker-fired pistols is effortless to pull and has low pull weights, allowing shooters of all shapes and sizes to operate the firearm more reliably under extreme stress. Striker-fired pistols require the slide to be pulled rearward, or “racked” back and released forward, pulling the firing pin rearward and capturing it under spring tension. The trigger releases the striker mechanism, allowing the spring tension to release and force the pin forward to strike the primer, firing the round in the chamber. 

Why Choose the Sig P320?
The real question is: why not? The P320 is a combat-proven semi-auto pistol, trusted by civilian and law enforcement shooters across the globe. Better yet, the P320 is the predecessor to the M18 duty pistol, adopted by the United States Army as the standard-issue sidearm for all US troops in 2018. The Nitron-coated stainless steel slide and anodized aluminum frame easily withstand years of heavy use and abuse in harsh tactical and personal defense environments, promising consistent, dependable operation when exposed to wet, sandy, cold, and other potentially corrosive environments. Plus, the P320 comes equipped with enhanced ergonomic grip panels for improved comfort and control with shooters of all shapes and sizes, making it the favored pistol design for a variety of law enforcement agencies, military personnel, and civilian shooters alike.
