One question people often ask about our vest is, "Will it stop a .50 Desert Eagle?" We weren't really sure. We did know that our vest stops a .44 Magnum, and stays within the National Institute of Justice backface deflection limits when doing so.
When you have a question and you need an answer, you can run an experiment, so we conducted a quick test at one of our retailer's ranges. We were very happy with the test. The Desert Eagle is a rare and very powerful handgun. It isn't likely you will ever encounter one, but it is nice to know that the bullet from one will not penetrate your BulletSafe vest.
