We have it. There is a chart out there if you google that shows the top carriers and comparisons. I like how they pay for defense cost up from vs. a reimbursement type which the NRA one does. Which means if you're in court, you pay all the attorney fees yourself and then get your money back.
But the NRA one is good that it has a free spousal endorsement at no charge. This was in 2018 when we had the NRA Carry Guard, so IDK if it's still available. But the NRA one did have to switch carrier s a few times since 2016 and is not allowed in WA due to their insurance commissioners decision.
For self defense insurance, it's not only for CCW or OC type carrying . It could be if you're inside your home and need to defend yourself as well. My CCW instructor in NV had a student use deadly force legally, but was sued by the guy he shot. He had to spend $40,000 for attorney fees and ended up winning as well. He never got that $40,000 back because he had no insurance and the suing party doesn't have the money. Anyone can sue you for any reason, but winning is another story.
