JIC:ADI was established to address the increasing demand citizens have for firearms training and armed defense instruction. Rather than build another gun business, we chose to build and grow a network of people, of all skill levels and abilities, with a range of interests from personal defense advocates to firearms enthusiasts . JIC:ADI was founded by Justin Lewter, certified pistol/rifle instructor with more than 5 years experience teaching marksmanship fundamentals and armed personal defense. Join our community. Follow our classes and schedule of events. Whetheryou are a student, instructor, or a proud practitioner of armed self defense, we’re here for you.
