To enable the debug menu, go to the pause screen, and go to the map/CompStat menu. At the menu, hold L1+R1, then let go of L1+R1 and hit right on the D-Pad, then hold L1+R1 right away(the last three steps must be done very quickly, within 1.5 seconds at the most).If done right you should have the music player up, and able to see the CompStat through the music player. When this is done, let go of L1+R1 and hit left on the D-Pad. This should bring you to the secret debug menu, where you can change most of the game's effects.

Extra Melee Weapon Slot
Simply throw your Nightstick. Then go to a trunk and equip another melee weapon. If you save and then load the data you will have the Nightstick back but will also have the extra weapon. Technically, this glitch gives you five melee weapon slots.
