I looked into CHL insurance when i first got my permit
But I found that the CHLPP plan insurance (above) only covers you up to and including the Grand Jury. If the Grand Jury fails to bill you, no problem. If they do, the CHL insurance walks away and leaves you holding the bag.
For that reason alone, I did not buy the CHL insurance. Just when you really need them, they leave you on your own.
I keep a lawyer's card with my CHL instead. He and I have spoken, he is a CHL holder himself, and he will be there if I need him.
