The P320 Full-Size is a striker-fired, short-recoil, locked-breech pistol chambered in .45 ACP, offering a 10+1 capacity and a 4.7-inch non-threaded barrel. Its full-size format delivers a generous sight radius and stable handling in a durable, duty-grade configuration.
The slide wears a Nitron finish and is cut with front and rear serrations for confident manipulation. Steel 3-dot sights are dovetailed front and rear, with sight-height numerals on top for easy identification. The sight radius measures approximately 6.6 inches.
At the core is SIG's modular, serialized stainless-steel fire control unit (FCU), allowing grip module changes while maintaining the same serialized component. The .45 ACP FCU and slide architecture are specific to .45 ACP and are not cross-compatible with 9mm/.357 SIG/.40 S&W P320 components. Takedown is tool-free and does not require pressing the trigger.
A full-length M1913 Picatinny accessory rail supports common lights and accessories. The pistol uses a standard curved trigger, and construction combines a polymer grip module with a stainless-steel receiver. Made in the USA.
