SIG SAUER Issues Voluntary Upgrade of P320 Pistol

P320 pistol meets requirements for industry and government safety standards; performance enhancements optimize function, safety, and reliability.

The Army's new handgun, the Sig Sauer P320, is a polymer-framed, striker-fired design, but there's a lot more.
P320 pistol meets requirements for industry and government safety standards.

SIG SAUERNewington, NH-( The 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 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.

Recent events indicate that dropping the P320 beyond U.S. standards for safety may cause an unintentional discharge.

As a result of input from law enforcement, government and military customers, SIG has developed a number of enhancements in function, reliability, and overall safety including drop performance. SIG SAUER is offering these enhancements to its customers. Details of this program will be available at on Monday, August 14, 2017.

The M17 variant of the P320, selected by the U.S. government as the U.S. Army’s Modular Handgun System (MHS), is not affected by the Voluntary Upgrade.

“SIG SAUER is committed to our approach on innovation, optimization, and performance, ensuring we produce the finest possible products,” said Ron Cohen, President and CEO of SIG SAUER. “Durability, reliability and safety, as well as end-user confidence in the SIG SAUER brand are the priorities for our team.”

OK, I win the pool. Sig has acknowledged a potential problem. Now for my next prediction. The military variant that Sig says is not affected by this recall, will have the enhancement already installed before delivery, or quietly done after deliver and issuance by military armorers. Some one who is really interested, or has an inside track will have to ferret this information out because I don’t like Sig’s in the first place so I have no interest in the issue except to win the pool. Now, now children, don’t get upset because some guy says he doesn’t like Sigs.… Read more »
