I have read the terms and conditions of NRA, USCC, and Law Shield policies. You best read them carefully before buying in. Get convicted of a crime in defending yourself, you don't get paid, and you have to pay back anything they advanced. They do not cover most legal costs but only reimburse them, if you comply with the terms and conditions. There are many pitfalls in their coverage but you have to read the small print of the policy not just the advertising claims.
Today at Rugertalk.com I epread about CCW Safe. It sounds great compared to the others, but I have not looked at the small print yet. I am going to do that later today.
