The last time I heard any numbers was in March, but back then Beretta had around 40 nanos returned in total out of 5,000 sold. Not all of those were for FTE issues, some had lose sights, some had finish irregularties. So based on those numbers you had about 8 tenths of one percent to get one with any issue. That is also assuming that all of the fte issues were gun related and not shooter or ammunition related. My nano is a great gun. Glad you like yours.
