Why wuold anyone buy or use something like this that would render their firearm inoperable. Might as well not have the firearm.
Clearly, education and training is the key ... but that is JUST the thing the gun grabbers do not want spread abroad because then every law abiding citizen's gun will be ready to use at a moments notice.
Scares the be-whillies out of those who want the guns removed and mystifies those untrained and unfamiliar with the real root issue of why firearms are so important in the first place.
This guys heart may be in the right place ... but the philosophy and the article are way off the mark IMHO.
Best to you.
