The announcement of the CZ SP-01 Accu Shadow's SSP disqualification (meaning it is illegal to use in IDPA at all) was made public, as far as I am aware, on September 8, 2014 at 10:05 PM. You can review this: http://idpaforum.yuku.com/topic/1152...-legal-for-SSP for reference.
The IDPA National Championship began on September 9, 2014; less than 24 hours from the announcement on the IDPA forum.
If you can explain how that doesn't square with what I said, I'm all ears.
