SIG SAUER is offering a voluntary program for all P320 pistols. As a commercial dealer based in the United States, you are eligible to participate in this program.

The upgrade will include an alternate design that reduces the physical weight of the trigger, sear, and striker while additionally adding a mechanical disconnector.
