Apparently a consistent problem with this locking system.  (I'm told the Taurus M9 clone does not seem to have this problem.)

But wait there's more

If you find a Vektor SP1 imported by IArms LLC of Jensen Beach Florida, you should make sure to inspect the locking block carefully before firing it. But Atlantic Firearms did do their due diligence in contacting their customers when they discovered the problem - they only had 10 of these guns to begin with and it was easy for them to contact each buyer without needing to post a notice in public.
