Updated 5:17 p.m. with concealed gun law information.
Missouri Gov. Jay Nixon announced late Friday afternoon that he has signed 22 bills and vetoed seven others.
One of the bills signed into law, House Bill 294, lowers the minimum age for obtaining a concealed guns permit to 21. The minimum age had been 23 - said by the National Rifle Association to be the highest in the country - since Missouri adopted its concealed weapons law in 2003.
