Did you notice this?
Evil catch-22. It's possible that the renewal could be approved after one's birthday, and it would then be impossible to issue a license that both A)Expires on one's birthday and B) Expires not less than 4 years nor more than 4 years from date of issuance.(3) SUBJECT TO SUBSECTIONS (8) AND (9), AN APPLICATION TO RENEW A LICENSE TO CARRY A CONCEALED PISTOL MAY BE SUBMITTED NOT MORE THAN 6 MONTHS BEFORE THE EXPIRATION OF THE CURRENT LICENSE. IF THE CONCEALED WEAPON LICENSING BOARD APPROVES THE RENEWAL, THE DATE OF ISSUANCE OF THE RENEWAL LICENSE IS THE DATE OF EXPIRATION OF THE CURRENT LICENSE OR THE DATE OF APPROVAL OF THE RENEWAL, WHICHEVER IS LATER, AND THE DATE OF EXPIRATION IS THE APPLICANT'S DATE OF BIRTH WHICH IS NOT LESS THAN 4 YEARS NOR MORE THAN 4 YEARS FROM THE DATE OF ISSUANCE.
Maybe that's a typo, but maybe not.
