SIG SAUER Issues Voluntary Upgrade of P320 Pistol

Sig Sauer has released an additional press release concerning the rumors surrounding the P320. For more information regarding these rumors, please see this previous post. The newest press release details the “voluntary upgrade” for affected P320 handguns to ensure the safety of usage. Please read on for additional information.


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

Newington, NH (August 8, 2017) – 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.”

  1. I have owned a sig since they came to the us with sig on one side and browning BDA on the other with a European heel release. I will send my P320 in although I have not had any issues with mine.

  2. So I’m confused. The civilian version has an upgrade available which owners will learn about on 8/14. Anyone who does not take advantage of this is a fool. Because you now own a gun for which a “safety” improvement is available but you chose not to avail yourself of it. Think Liability! Next is the military version. Why is the military version not affected? Is it because the update was already on the guns supplied to the military? If this is the case why was it not also furnished on civilian guns? If it is not, why would the military accept a gun for which a safety upgrade, especially one dealing with military rough handling which increases the possibility of a drop? Or is the military going to do the upgrade itself? In which case why would they accept a deficient product, and absorb the cost, above and beyond, what is already very high unit price? Sig generally has an excellent reputation for top quality products (full disclosure: I don’t like them because of high bore axis.) but I can’t help but believe they are fumbling the ball in this case, and fumbling, and fumbling…..

    • Maybe the military contract variant has a dissimilar mechanism than the civilian version; perhaps, it has a manual safety, which has long been a requirement of the U.S. Army for its pistols.

    • No other gun was tested in the same manner as the P320 with the drop at the 30 degree angle. I have two P320’s and have not been able to replicate the issue brought forth by a gun store. Nor, have I seen the full, unedited videos with the test methodology. It would be interesting to see if any of the other brand would experience the same issue.

  3. I bought a Sig P238 brand new from a reputable dealer a few years ago and it broke the first time I pulled the trigger. They are not as great a company as they would have you believe. They are like any other company out there, they use their customers for product testing. This is why I am sticking with H&K.

  4. I’m writing you because of the article in my NRA Rifleman magazine. It states that the military has the option of choosing a M17 orM18. Is this the upgrade you are talking about if not what is the difference between the M17 and M18?

    • The military version has some different specs. It also has a manual safety as required by the military requirements. Additionally, Apex, who makes aftermarket triggers was not able to replicate this on the 45. There are far more negligent discharges from people disassembling their Glocks than from dropped Sigs. I also know of a Glock discharging in a holster due to a worn firing pin safety plunger and cracked frame rail. Any firearm can have an issue. It appears that Sig is taking this seriously enough to offer a fix for those that feel it necessary. The firearm meets all safety standards for drop testing by SAMMI, NIJ and others. The reason that it is a voluntary product update is versus a recall is that the likelihood of a 30 degree drop at the right height is so remote that it is there to provide those that are concerned enough to have the firearm upgraded.

    • The M17 is the military equivalent of the full size pistol. The M18 is the Sig P320 Compact size. The military firearms are slightly different than the civilian models.

  5. ANY striker fired pistol is inherently less safe than a pistol with a hammer and a safety. No safety means more AD’s and more injuries and deaths. Yeah, yeah, training makes it safer up until contact and then all that goes out the window and the guy on the ground being cuffed gets a round through his back. More and more examples of the pistol with no safety going off “accidentally” are available every day. The Oakland subway shooting, the guy in teh Wal Mart parking lot, the idiot ATF agent in the classroom, and more. The Army will use them only so long before Soldiers are shooting themselves and each other and then shit can the lot….
