As per my conversation with Chad please build holster for a standard Hellcat with the open bottom of the barrel / slide area cut to fit an RDP weapon ( ie to allow compensator to protrude through bottom of opening similar to what a weapon sitting in a yaqui slide would look like ). Any questions you can check with Chad or please call me direct at 203-228-3634. Thank you
