Yes. The P320 meets and exceeds all US safety standards. However, mechanical safeties are designed to augment, not replace safe handling practices. Careless and improper handling of any firearm can result in an unintentional discharge.
This will include an alternate design that reduces the physical weight of the trigger, sear, and striker while additionally adding a mechanical disconnector.

Note regarding Invalid Serial Message: If your P320 was manufactured after our voluntary upgrade program started (August 8, 2017), it already includes the upgrade by default, which is why our system may not recognize the serial number. For P320s produced before this date, please double-check your serial number to ensure it's entered correctly. If you're still experiencing issues, don't hesitate to contact our customer service team for assistance.
Thank you for choosing SIG SAUER.
Your P320 serial number can be found by looking on the right side of the pistol grip. The serial number will be stamped into the receiver. This number should be entered into the first entry field of the form. SKU will automatically populate if your P320 is on a qualified list of U.S. Domestic consumer serial numbers.
With some exceptions, most U.S. Domestic Consumer P320 serial numbers begin with “58A”, “58B”, or “58C”, followed by six numbers.
NOTE: There are no “i”s or “o”s in the numerical portion of the serial number.
The updated slide will feature a disconnect notch near the striker assembly. The mechanical disconnector provides an additional level of safety against cartridge failure events. Additionally, the mechanical disconnector prevents a “dead trigger” condition if the trigger is pulled while the slide is retracted.
These changes are expected to refine functionality for the pistol and improve both its ergonomics and performance.
The new trigger for the P320 pistol will feature a thinner profile and reduced mass. This is expected to improve the trigger-pull experience.
Yes. The P320 meets and exceeds all US safety standards. However, mechanical safeties are designed to augment, not replace safe handling practices. Careless and improper handling of any firearm can result in an unintentional discharge.
SIG SAUER is offering a voluntary program for P320 pistols. This will include an alternate design that reduces the physical weight of the trigger, sear, and striker while additionally adding a mechanical disconnector.
Through additional testing above and beyond standard American National Standards Institute (ANSI)/Sporting Arms & Ammunition Institute (SAAMI), National Institute of Justice (NIJ), Department of Justice (DOJ), Massachusetts, California, and other global military and law enforcement protocols, we have confirmed that usually after multiple drops, at certain angles and conditions, a potential discharge of the firearm may result when dropped. Although it is a rare occurrence, with very specific conditions, SIG SAUER is offering an upgrade to all of its current P320 owners.
The language used in major manufacturers’ owner’s manuals with regard to drop safety is consistently written to warn the user that dropping a loaded firearm is not recommended and could possibly result in an accidental discharge. All precautions should be taken to avoid dropping a loaded firearm. Although extremely unlikely, it is still possible for any loaded firearm to discharge when dropped.
Due to the modularity of the pistols, which all share the same trigger group, all calibers and pistol sizes are affected.
A variety of calibers and brands of ammunition were used. NOTE: Loaded ammunition is not used for drop testing, only primed cases with the powder and projectile removed are used.

The new design has a physically lighter trigger, sear, and striker assembly with the addition of a mechanical disconnector.
Yes. However, the X-series flat trigger will not be replaced.
You should send any and all P320 slides with your shipment, as the striker(s) will be replaced, and the slide(s) will need the disconnector cut. You should also include the grip module for subcompact models as these need to be replaced as part of the upgrade as well.
No, the MHS pistol is a different variant of the P320 platform. It has passed the US Army’s testing protocols (TOP).
There are four options based upon what type of consumer you are:
No. The upgrade is being offered to our consumers at no cost.
Yes
This is a voluntary service, as the P320 meets and exceeds all ANSI/SAAMI, NIJ, DOJ, California, Massachusetts, and safety standards. Sig Sauer welcomes all of its P320 owners to take advantage of this program.
DO NOT RETURN YOUR P320 WITH ANY MAGAZINES, AFTERMARKET TRIGGER GROUPS, OR ACCESSORIES SUCH AS OPTICS, LIGHTS, OR LASERS. IF YOU SEND YOUR FIREARM IN WITH AFTERMARKET ACCESSORIES, SIG SAUER CANNOT GUARANTEE THAT THOSE ITEMS WILL BE RETURNED TO YOU.
No. The functional enhancements have been made for all current and future P320 shipments.
For the US Commercial market, once your P320 is received at Sig Sauer, turnaround time will be approximately 3-4 weeks. Transit times may vary depending on your geographic location and receipt of your returned pistol.
No. This work must be done at the SIG SAUER factory.
Please visit our Voluntary Upgrade page and enter your serial number to determine if your serial number is affected.
Yes
The most obvious external difference is the lightweight trigger. It has a thinner profile than the standard curved trigger. The other changes are minimal and would likely not be noticed.
Minimal reported drop-related P320 incidents have occurred in the US commercial and law enforcement markets, with hundreds of thousands of guns delivered to date. These instances occurred in conditions that appear to be outside of normal testing protocols. The current P320 design meets and exceeds all US safety standards. As it relates to the ad hoc media drop tests, these were not part of standardized testing protocols, and they were performed using firearms in unknown conditions.
NO. SIG SAUER DOES NOT RECOMMEND THAT ANY CONSUMER PERFORM DROP TESTING BEFORE OR AFTER THIS UPGRADE. Mechanical safeties are designed to augment, not replace safe handling practices. Careless and improper handling of any firearm can result in unintentional discharge. Be aware that ad hoc testing is occurring and individuals are testing guns in conditions outside accepted testing protocols. ALL STANDARDIZED DROP TESTING IS DONE IN CONTROLLED ENVIRONMENTS WITHOUT USING LIVE AMMUNITION.
Yes, the pistol can be returned with any factory trigger components.
Please remove your aftermarket trigger components and send back your pistol without a trigger.
SIG SAUER can only guarantee the function and safety of original and upgraded SIG SAUER trigger components. Any questions regarding aftermarket components should be directed toward the aftermarket manufacturer.
Yes
No, this is not part of the upgrade.
There is no change to the grip module for full size, compact, and carry variants. The changes are only in the metal receiver frame and the slide. The one exception is any subcompact variant. Subcompact versions of pistol will be returned with a new grip module that has a beavertail design in line with the other 320 sizes in order to effectively take advantage of the upgraded components.
Not for the full size, compact or carry kits. Only the upper components are required so we can update and test fire using the CALX kit (slide, barrel, recoil spring, and guide rod). However, subcompact kits should come back with the grip module so we can swap it out.
No
The slide is made of stainless steel so we will not be refinishing that small area. It is no different than hammer ramps on the bottom of the slide that get polished or wear. The exposed metal has no issue with corrosion.
No, the upgrade will only be performed if you elect to be part of the Voluntary Upgrade Program.
You will be able to track the arrival of your P320 at SIG SAUER by checking the tracking number on the prepaid shipping label provided by SIG SAUER. From there, the next communication you will receive is return tracking information once your pistol is shipped back to you.
No
Some states have legal restrictions for the purchase of items so we need to ask for your location.
Some products have purchase restrictions for those under the age of 21, please verify your age.
