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

NOTE: There are no “i”s or “o”s in the numerical portion of the serial number.
