Good idea, the TAK Impactor Training Gun. When we used a standard-issue blue gun (inert) in a Krav Maga course I was aware of the danger, should a participant get carried away. Which reminds me: are you ready for close-quarters combat? You know; with a gun? Do you have a plan? Have you had any training in that regard? Both in terms of shooting from the ground and counter-attacking an assailant to get to your gun?
