Mississippi requires no license to carry a loaded or unloaded pistol or revolver on the person in a sheath, belt holster, or shoulder holster, or in a purse, handbag, satchel, similar bag, briefcase, or fully enclosed case. The fully-enclosed-case exemption traces to 2015's SB 2394, and the sheath/holster language was added by 2016's HB 786 (Church Protection Act), effective July 1, 2016.
"No license shall be required under this section for a loaded or unloaded pistol or revolver carried upon the person in a sheath, belt holster or shoulder holster or carried in a purse, handbag, satchel, other similar bag or briefcase or fully enclosed case."
