SIG Sauer Issues Voluntary Upgrade of P320 Pistol

Picture shows the new SIG Sauer polymer-framed P320.

I am sure many of you have already read internet chatter or watched a YouTube video regarding the SIG P320 failing drop tests. This is true, false, and somewhere in between. To be honest, this is not “new” news. Word spread at the 2017 NRA Show about the SIG P320 having a trigger issue. SIG Sauer P320 pistol right All SIG P320s that have been sold to date, regardless of when it was manufactured, will pass all industry and government standards for drop testing. This is due to the way the drop test is conducted. Current drop tests call for the pistol to be dropped with the barrel down or on flat on its side. The current issue was first noted during testing by the German police who perform drop tests at something like 25 different angles. One of these angles did in fact fail, which led to the new trigger design. In fact, SIG already had a replacement trigger used in the M17 P320 military contract.

So, what have we learned? The SIG P320 will pass all industry and government drop tests. Which puts it on par with every other pistol on the market today. It does have an issue if dropped in a particular manner, at an exact angle (something around 30 degrees), where contact is made to both the slide and frame simultaneously. Could this be the case with any other pistol you own or would potentially buy? Sure, but how many of us are willing to drop out guns on concrete from two meters 30 or so times to find out? That is not to say this is all hoopla to be unconcerned with. Even SIG Sauer admits that. While any of us could own a pistol with an unknown issue, few of us want one with a known issue. Although the P320 does meet all U.S. standards, SIG has stepped up to the plate by offering a voluntary upgrade. What does that mean? Well, we do not exactly know. SIG Sauer has released the following press release promising full program details on Monday August 14. Here is the release from SIG Sauer.

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.

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 3 Sig weapons and none have ever failed our family. When I first heard about this issue at large, my friends and I performed several drop test on all of our pistols. Not one of our weapons discharged during any of the test performed. We used 4 brands of arms and 3 calibers of each of the arms.
    My biggest concern runs along with a chambered round in any kind of revolver, revolvers have always been known to discharge when a live round is in the chamber and it happens to land on the hammer head.
    But please be thoughtful on how you would perform your own personal test in a very controlled area, meaning controlling any stray rounds.

  2. I want to see other popular guns drop tested in this new way
    It would be extremely interesting to know if Glock, Smith, Ruger, CZ striker fired models have this problem with non standard drop testing
    Sig came out with a fix immediately and is paying the postage both ways to fix it
    Seems like great customer service to me

  3. I had heard about this issue shortly after purchasing my first P320. I wasn’t real happy that Sig was already having an issue when they will be mass producing these handguns for the military and for people like myself. I have (2) Sig P320s, .357 Sig and .40 S&W. I am always careful when drawing my weapons or re-holstering them.
    The problem is that most of my weapons I have to wear in a shoulder holster because, basically, I have no hips and anything bigger than a single stack usually protrudes out enough to print. Being that the P320 is a double stack, I usually have to carry it in a shoulder holster. I have to be extra cautious because of this known defect and I carry with one in the chamber. It gets very hot where I live so wearing extra clothing to cover the weapon is not an option in the summer. I hope that Sig can give us an easy fix but also remember that swapping out the whole trigger assembly is not an option because (The Gun) serial number is on it. Anyway….I hope Sig comes up with a solution soon!

  4. Sig knew about the problem and denied it. Now they are offering to “volunarily upgrade” their pistols. They need to recall them. I have lost all faith in Sig as a company. I will not be buying any more of their products.

    1. Since they marketed the gun in good faith, it passed drop standards in different trials, they are legally off the hook. They are doing what they can in this voluntary upgrade.
      It appears that they may have found about this before it hit the net and had a solution already. If the gun has to be dropped from 2 meters at a 30 degree angle vertically on concrete to fire, think about it. That is not a drop from standing to the ground while holstering or even shooting the firearm, for anyone but maybe Wilt Chamberlain. The rest of us would have to be standing on a stool or ladder for this to happen.
      Sig is NOT going to open themselves up to a lawsuit on a government certified firearm, that would be corporate suicide. Stepping up to the plate now, after what had to be very contensious meetings in the last couple of days, with a solution to the problem speaks volumes.
      How many firearm companies have left potencially dangerous triggers, knowing there was a problem, but being to scared to fix them?
      This is a breath of fresh air coming from a huge multinational corporation.

    2. It doesn’t seem to take a 2 meter drop and I don’t care if they passed a test. They are selling a gun that can fire if dropped or is hit on the butt end. The worst part is they initially denied the problem and later denied they knew about it. They have earned a place on my boycott list.

    3. A company that is willing to fix a defect no questions asked. Imagine that. The p320 is still a superior firearm in my book
