Federal Register :: Implementation of the NICS Improvement Amendments Act of 2007 Worth reading if you are on SSI disability for a mental health condition or have a family member in this situation. This was particularly disturbing "We will use our regular program rules to determine whether an individual is disabled due to a mental impairment that is severe enough to meet the requirements of our mental disorder listings" The government, not your doctor, will determine if you have a mental impairment severe enough to be added to NICS for denial. Also, I've had patients who got on disability who designated someone to manage their finances for convenience. I've had patients where the person at the SSI office recommended it for that reason alone. Be aware that they could use that against you to determine you are unfit to purchase firearms. If you are young and healthy, consider getting a private disability insurance.
