FN Service Bulletin: FNS Family of Pistols

FN recently became aware of a condition found within the FNS family of pistols that, under a very limited and unlikely set of circumstances, could cause the pistol to delay fire after the trigger is initially pulled.  This condition can only be replicated in FNS pistols manufactured before February 12, 2017.

To our knowledge, this delayed-fire condition has only occurred in controlled testing environments; FN has not received any reports of delayed fire in the field under these unusual circumstances.

The condition may result after the FNS pistol slide is forced out of battery at a very small and specific distance, such as what might occur if the muzzle end of the slide is pressed against an object, and the trigger is pulled.  The pistol functions as designed and does not fire. However, if the condition occurs, one of two scenarios may result: (1) if the trigger is held to the rear, the pistol could delay firing until the time when the slide moves back into battery, or (2) if force is removed from the trigger and the slide moves back into battery, the pistol could fire if jarred.  In the unlikely event that scenario (2) occurs, keep the pistol pointed in a safe direction and rack the slide to the rear to reset the pistol.  Avoid a “tap, rack, bang” clearing sequence.

While this condition is highly unlikely to occur in the normal course of operation, out of an abundance of caution FN is offering to substitute the striker in affected FNS-9, FNS-9 Longslide, FNS‑9 Compact, FNS-40, FNS-40 Longslide, and FNS-40 Compact pistols free of charge. Once the striker is replaced, the condition no longer occurs.  Not all FNS serial numbers are affected by this condition. Therefore, FNS owners are asked to please use the serial number lookup found below. If the pistol is affected, further instruction on returning the FNS for service will be provided. Note: Please do not ship any affected product to FN until a FedEx label has been generated and sent. If the firearm is not affected, a message stating such will be displayed.
