The SIG Sauer P320 meets U.S. standards for safety, including the American National Standards Institute (ANSI) / Sporting Arms Ammunition Manufacturers' Institute, Inc. (SAAMI), National Institute of Justice (NIJ), as well as rigorous testing protocols for global military and law enforcement agencies, the company stated.
The design of the SIG Sauer P320 overcomes the most significant safety concern in striker-fired pistols today: the practice of pressing the trigger for disassembly. This can be performed with a round in the chamber which has resulted in numerous incidents of property damage, physical injury, and death. The disassembly process of the P320, however, uses a take-down lever rather than pressing the trigger, eliminating the possibility of discharge during the disassembly process.
