Vickers mag release IDPA legal

I have signed up for the Carolina Classic IDPA match. Are Vickers mag release (gen5) glock legal for CO or do I need to swap back to factory?

THANKS
Steve

IDPA CO is ESP with a dot. Not many limits.

Without the RDS, but with the Vickers release, it could be run in either ESP or CCP, but not SSP.

Best, Jon.

thanks, im bringing a factory (FBI) one with me just in case
