Blue Mags are unique inert training magazines. They are made out of a solid synthetic plastic that is weighted to give the same feel as a fully loaded magazine. They are the safe, realistic alternative to loaded magazines for tactical reloading drills and dry fire training. Zero possibility of an accidental discharge and no more dropped and dented magazines. Instructors can tell at a glance if a student's handgun contains a blue mag or a live magazine. Blue Mags allow you to improve your training, increase your safety, and preserve your magazine life. Available in 4 styles.
