[Max-imus]

With an NPC Server you can just delete it from the level and then delete it from the weapons database.

On a playerworld without an NPC Server, just put this in the weapon you want to delete

if (playertouchsme) {toweapons weaponname;}
if (weaponfired) {sleep.1;destroy;}
if (isweapon){sleep.1;destroy;}

If the original weapon isn't on the server anymore, just make a new npc with an image, put that script in the npc, and make sure the weapon name is the same.
