Interesting timing of your inquiry, I am just sitting down after completing my CCW class, now have that certificate to present w/packet.
My three recc'd. letters are still not completed.
One of my letters is coming from active LEO so I'm not pressing it's completion. The other two are from retired professionals, and I'm having some difficulty crossing paths with them. Now that the CCW class has been completed, I'm putting the process back on front burner.
