I bought some of the stuff. It is expensive. After reading the info from some of the responders, I have some doubts about the lethality of Magsafe. The Strasbourg tests are seemingly legendary, meaning not scientifically noted. If attacked by Alpine goats you need the Magsafes. I may mix them with the xtps in my .25 cal mouse gun. Don't laugh a .25 in your hand is better than a .45 back home in the gunsafe. I usally carry a .380 and a couple of Magsafes in the magazine might be useful. My wife has the .25 in her pocket book and it gives her a feeling of safety. At 70 she is not a great street fighter but she will shoot someone.
