JEFFERSON CITY, Mo. -- The Missouri House of Representatives Wednesday gave first-round approval to legislation that among other things, lowers the age for citizens to carry concealed firearms from 23 to 21. The first major change to Missouri concealed weapons law since its inception also specifies that state legislative staff members and staff members of elected officials who possess concealed carry permits may carry their weapons in the State Capitol. Lawmakers and state elected officials already have that right. An effort to lower the conceal and carry age from 23 to 18 was defeated on a floor maneuver. The bill, sponsored by Rep. Jeanie Riddle, R-Mokane, passed by a voice vote. A recorded vote will follow before the bill can move on to the Senate.
