Modifies provisions relating to concealed carry permits

HB 2135 modifies Missouri's concealed carry permit system by establishing new eligibility rules and validity periods. It requires applicants to be at least 18 years old (or a member of the U.S. Armed Forces), meet residency or military status requirements, and have no disqualifying criminal history (including certain violent misdemeanors or drug offenses within five years). Permits would be valid for five years from issuance, and failure to renew within that period could trigger federal background check restrictions under 27 CFR 478.102(d). This bill directly affects Missouri residents and military members seeking concealed carry permits, replacing previous rules with updated criteria for permit issuance and renewal.
