Originally conceived by personal protection specialist and GG&G Technical Advisor Lance Harris, the new Tactical Impact Device (TID) fits easily on the bezel of the flashlight and is secured from removal by four small socket head screws. Manufactured from 4140 steel, it has a manganese phosphate finish. Although lightweight (from 0.05-pound to 0.10-pound, depending upon the model), the GG&G TID adds sufficient heft to the front end of the flashlight to accelerate the forward momentum during the thrust stroke. Its sharp, 5-teeth-per-inch pattern surrounds the entire bezel and provides an aggressive, and extremely effective, alternative to lethal force. As Lance Harris so aptly said in a recent interview; “The GG&G TID was developed to de-fang an opponent through the use of trapping and pressure-point-compliance techniques. There is no other alternative force tool available that offers the concealability, and versatility of the TID.”
