A tactical device holster (TDH) system is described that is a complete carry and deployment solution allowing for split-second deployment of hand-held non-lethal/lethal deployable devices (HNLDD) by tactical personnel. The TDH system allows tactical personnel to deploy HNLDDs without having to disarm because deployment requires only a single hand, and the TDH system indexes the HNLDD in the proper position for deployment. The TDH system allows the HNLDD to go from secure carry to deployment in under one second while not impeding the deadly force option during deployment. The TDH system keeps the fuze lever of the HNLDD fixed in a pre-specified position. The HNLDD is not altered for use with the TDH system and allows quick insertion of the HNLDD. The TDH system supports numerous HNLDDs and tactical pyrotechnic and incendiary devices, and can be fixed to various tactical clothing, vests, holsters, equipment, and vehicle components.
