pawn Code:

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate = PLAYER_STATE_DRIVER || newstate == PLAYER_STATE_PASSENGER)
    {
          if(GetPlayerWeapon(playerid)) == 24)
          {
           SetPlayerArmedWeapon(playerid, 0);
          }
    }
return 1;
}

Edit: Oh I just noticed you made that post, you must done it when I was making this post. Good to hear you found out what you needed!
