The day before IDPA Nationals, IDPA sent out an email banning the CZ Accu-Shadow from SSP (Stock Service Pistol) division.

Caleb, over at Gun Nuts Media, explains why the CZ Accu-Shadow is illegal based on a review of IDPA rules.

To understand why the Accu-Shadow is illegal for SSP, you have to understand what the Accu-Shadow is. It is a custom variant of the CZ75 Shadow, which has an external barrel bushing fitting to it in order to improve accuracy. Barrel bushings are on the list of prohibited modifications in SSP.The Accu-Shadow is made by CZ Custom. CZ Custom is not a division of CZ-USA, but is in fact an independent company. CZ-USA may list the Accu-Shadow on their website, but because the bushing is not an OEM part made by CZ and fitted by CZ, the modifications to the Accu-Shadow make it illegal for SSP, and by default then illegal for IDPA. It’s the difference between a Roush Mustang, which is modified by a third party, and a Mopar Challenger. Dodge owns Mopar, Ford doesn’t own Roush.

It seems a rather ill-timed choice to announce the ban a day before a big match. The ruling could have been worse, but it seems they could have announced it sooner to give competitors more time to choose a back-up pistol to compete with.
