Just thought I'd put this out there for others, like myself, who also have a Sig P320 in their firearm collection. Sig Sauer is offering a voluntary upgrade on these firearms due to the possibility of an accidental discharge if the pistol is dropped in a certain way. The announcement in the link below comes from their website - they are saying there will be more details coming out Monday (8/14/17). Just wanted to get the information to others who may have this pistol in their collection.
