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.
3 Steps To Upgrading Your SIG SAUER P320 Pistol
- Enter your serial number to the right to see if your P320 has already been upgraded.
- If the message indicates your pistol has not been upgraded, reach out to SIG SAUER Customer Service at 603-610-3000 option 1 (8:00am – 5:30pm EST)
- Have your P320 serial number and home address available for the customer service representative.
Once SIG SAUER receives your P320 pistol, they will apply the upgrades, test it, and then return it to you free of charge.
If you own multiple P320s, you will need to enter each P320 serial number separately.
