SIG SAUER Announces Details of Free P320 ‘Voluntary Upgrade’ Program

Last week, SIG SAUER announced that they will be offering a “voluntary upgrade” program to owners of the 500,000 P320 pistols that have been sold since the gun was first introduced. This was prompted by reports that the P320 can fire when dropped. SIG decided to offer an upgraded trigger pack — one they’d designed for the M17 Modular Handgun System — for all P320 pistols that had been sold commercially.

Given the speed at which the reports and SIG’s response happened a week ago, the company needed some time to work out the logistical details. That’s now been done and SIG SAUER will upgrade the pistols free of charge. Here’s how the program will work:

3 Steps To Upgrading Your SIG SAUER P320 Pistol

1. Have your P320 serial number and home address available.

2. Fill out the Voluntary Upgrade Sign-Up Form — one serial number per form submission.

3. SIG SAUER will contact you regarding the best method for you to get your P320 pistol to them.

Once SIG SAUER receives your P320 pistol, they will apply the upgrades, test it, and then return it to you free of charge.

How to locate your P320 Serial Number

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.

– Example: 58Axxxxxx


Is my P320 safe in its current configuration?
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.

What is the P320 Voluntary Upgrade Program?
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.

Why is this upgrade happening?
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 (MGL, Chapter 140, Section 123) 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.

Does the owner’s manual say it can be unsafe?
The language used in major manufacturer’s 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.

What calibers and models are affected?
Due to the modularity of the pistols, which all share the same trigger group, all calibers and pistol sizes are affected.
