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.
