The Company also announced the results of recent tests on the effectiveness of certain of its chemical irritant self-defense projectiles, which testing was undertaken following a complaint from one user that he had received an ineffective round. “As soon as we heard there was a possible issue we advised all customers not to rely on the rounds for self-defense pending results of an inquiry and shipped free replacement rounds to all customers,” explained Ganz. While the Company found no problem with the Byrna Black rounds originally provided, the testing process led to some refinement of the Byrna Black formulation. These changes have made the rounds even more effective. “They are faster acting, longer lasting, and have an even greater deterrent effect,” Ganz elaborated. “I personally witnessed some of the testing and I would not want to be a would-be assailant hit with our rounds.” The Company sells the Byrna HD in the United States on its e-commerce site and in South Africa through Dave Sheer Guns.
