                           File No. 333-48456

Ladies and Gentlemen:

     This letter is in response to certain  comments  from Mr.  Robert Lamont of
the Staff with  respect to the Trust's  Post-Effective  Amendment  No. 24 to its
Registration  Statement  on Form N-1A  filed with the  Commission  on August 16,
2006.  Where noted,  changes,  as  applicable,  have been made to the Prospectus
and/or  Statement of Additional  Information.  All page references  refer to the
pages of these  documents  which  have  been  marked  to show  changes  from the
previous versions included in Post-Effective Amendment No. 24.

1.   Comment: Please include Tandy language in your response letter.

     Response: The request language is included in this letter.


2.   Comment: Under the heading "Understanding the Trust", the Registrant states
     that there are  forty-six  portfolios  but the first page of the SAI states
     that it applies to forty-four investment portfolios. This disclosure should
     be consistent.

     Response: The SAI only covers 44 of the 46 Met Funds. A separate SAI covers
     two ETF funds.




3.   Comment: Under the heading  "Understanding the Portfolios",  the Registrant
     states  that  "[e]ach  Portfolio  is well  diversified  . . ." Should  this
     sentence  say   "non-diversified"   or  "diversified"   rather  than  "well
     diversified." Please note that on page 8, the Registrant indicates that the
     Strategic Growth and Income Portfolio is "non-diversified."

     Response:  The  disclosure  on page 3 has been  modified  to  delete  "well
     diversified." Revised page 3 is attached.

4.   Comment: On page 7, at the bottom of the page there is a disclaimer in bold
     print.  This disclaimer  should either be added or moved to the front cover
     page of the prospectus.

     Response: All of Met's current prospectuses have the same disclosure in its
     position  just  prior  to  the  disclosure  of  Portfolio  objectives,
     policies and risks. It is proposed that at the next annual update, the
     disclaimer will be moved to the appropriate place.

5.   Comment:  On  page  8,  in the  fourth  paragraph  down  from  the  heading
     "Principal  Investment   Strategy",   the  Registrant  states  that  "[t]he
     Portfolio  is  non-diversified,  which  means that it may  concentrate  its
     assets in a smaller number of issuers than a diversified portfolio". Please
     revise this  disclosure so that the word  "concentrate"  is not used in the
     context of diversification.

     Response:  The  requested  revision  has been  made  with  respect  to each
     Portfolio. Revised page 8 is attached.

6.   Comment: Please note that when a fund invests in affiliated funds, the fund
     must  aggregate  the  amount of  investments  of all  underlying  funds for
     purposes of concentration.

     Response:  Disclosure  has been added to the SAI  regarding the
     aggregation  of underlying  investments  in affiliated  funds for
     concentration  purposes.  Revised page 47 of the SAI is attached.

7.   Comment:  On page 10, it would be helpful if for each  primary risk listed,
     the Registrant  would include one or two sentences  describing the risk and
     refer readers to the back of the prospectus for more detailed  descriptions
     of the primary risks.

     Response:  The style of all Met  prospectuses  is to list the risk factor
     with a cross  reference to the section on primary  risks.  It is believed
     that the current format is clear and adequately presents the risks
     involved for each Portfolio.

8.   Comment:  On the back cover page,  the public  reference  room's  telephone
     number is 202-551-8090.

     Response: The requested change has been made.


9.   Comment:  On page 28, for both the Manager and the Adviser,  please include
     more disclosure about their experience.

     Response: The requested  disclosures have been added.  Revised pages 28 and
     30 are attached.

10.  Comment:  On page 32,  in the  discussion  of  voting  in the  second  full
     paragraph,  please state whether or not there is a minimum  number of votes
     that is required for a quorum. If the Registrant uses echo voting or mirror
     voting,  please  state that as a result of using  such a voting  method the
     disposition   of  a  matter  may  be   determined  by  a  small  number  of
     shareholders.

     Response:  The  requested  disclosure  has been added.  Revised  page 32 is
     attached.


         In connection with this filing, the Trust acknowledges that: (1) the
Trust is responsible for the adequacy and accuracy of the disclosure in the
filings; (2) staff comments or changes to disclosure in response to staff
comments in the filings reviewed by the staff do not foreclose the Commission
from taking any action with respect to filing; (3) the Trust may not assert
staff comments as a defense in any proceeding initiated by the Commission or any
person under the federal securities laws of the United States.

         The Trust will file a 485(b) filing on November 1, 2006.

         If you have any questions, please feel free to call me at (202)
775-1205.


                                                Very truly yours,



                                                /s/ Robert N. Hickey

  INTRODUCTION

     Understanding the Trust

         Met Investors Series Trust (the "Trust") is an open-end management
investment company that offers a selection of forty-six managed investment
portfolios or mutual funds, only three of which are offered through this
Prospectus (the "Portfolios"). Each of the three Portfolios described in this
Prospectus has its own investment objective designed to meet different
investment goals. Please see the Investment Summary section of this Prospectus
for specific information on each Portfolio.

Investing Through a Variable Insurance Contract

         Class B shares of the Portfolios are currently only sold to separate
accounts of certain affiliates of Metropolitan Life Insurance Company
(collectively, "MetLife") to fund the benefits under certain individual flexible
premium variable life insurance policies and individual and group variable
annuity contracts (collectively, "Contracts").

         As a Contract owner, your premium payments are allocated to one or more
of the Portfolios in accordance with your Contract.

         Please read this Prospectus carefully before selecting a Portfolio. It
provides information to assist you in your decision. If you would like
additional information about a Portfolio, please request a copy of the Statement
of Additional Information ("SAI"). For details about how to obtain a copy of the
SAI and other reports and information, see the back cover of this Prospectus.
The SAI is incorporated by reference into this Prospectus.

[SIDE BAR:

         Please see the Contract prospectus for a detailed explanation of your
Contract.]

                  Understanding the Portfolios


Each Portfolio was designed on established principles of asset allocation and
risk tolerance. Each Portfolio will invest substantially all of its assets in
other portfolios of the Trust or of Metropolitan Series Fund, Inc. (the "Fund")
which invest either in equity securities, fixed income securities or cash
equivalent money market securities, as applicable ("Underlying Portfolios").
Each Portfolio has a target allocation among the three primary asset classes
(equity, fixed income and cash/money market). The Adviser establishes specific
target investment percentages for the asset classes and the various components
of each asset category and then selects the Underlying Portfolios in which a
Portfolio invests based on, among other things, the Underlying Portfolios'
investment objectives, policies, investment processes and portfolio analytical
and management personnel. The Adviser may add new Underlying Portfolios or
replace existing Underlying Portfolios or change the allocations among the
Underlying Portfolios, dependent upon, among other factors, changing market
dynamics, changes to the personnel, investment process, or criteria for holdings
of the Underlying Portfolios, or the availability of other Underlying Portfolios
that may provide a risk-adjusted benefit to a Portfolio. Information regarding
                                -3-




                       Strategic Growth and Income Portfolio


Investment Objective:

         Seeks both growth of capital and income where growth of capital takes
precedence over income.

Principal Investment Strategy:

         The Portfolio seeks to achieve its objective by investing in Class A
shares of a diversified group of Underlying Portfolios of the Trust and of the
Fund. Under normal circumstances, the Portfolio primarily invests in large cap,
small cap, mid cap and international equity Underlying Portfolios and also
invests in fixed income Underlying Portfolios in accordance with targeted
allocations of 65% to equity Underlying Portfolios including Underlying
Portfolios that invest in real estate investment trusts (REITs) and 35% to fixed
income Underlying Portfolios. The names of the Underlying Portfolios in which
the Portfolio may invest and the approximate percentage of the Portfolio's
assets allocated to various types of equity and fixed income Underlying
Portfolios, as of the date of this Prospectus, are set forth above in
"Understanding the Portfolios."

         The Portfolio seeks to achieve capital growth through its investments
in Underlying Portfolios that invest primarily in equity securities. These
investments may include Underlying Portfolios that invest mainly in stocks of
large established U.S. companies as well, to a lesser extent, in stocks of
foreign companies and smaller U.S. companies with above-average growth
potential.

         The Portfolio seeks to achieve current income through its investments
in Underlying Funds that invest primarily in fixed income securities. These
investments may include Underlying Portfolios that invest exclusively in bonds
of U.S. issuers as well as Underlying Portfolios that invest in U.S. and foreign
investment-grade securities, as well as Underlying Portfolios that invest in
high-yield, high-risk bonds, commonly referred to as "junk bonds."


         The Portfolio is non-diversified, which means that it may invest its
assets in a smaller number of issuers than a diversified portfolio. However, the
Portfolio invests its assets in the Underlying Portfolios, each of which
generally has diversified holdings.


         As of the date of this Prospectus, the Portfolio currently plans to
invest in the following Underlying Portfolios and cash or cash equivalents at
the approximate percentages indicated:

                                       -8-



         With respect to swaps, a Portfolio (except for the Lord Abbett Bond
Debenture, Lord Abbett Mid-Cap Value, Lord Abbett America's Value, Lord Abbett
Growth and Income, Pioneer Fund, Pioneer Mid-Cap Value and Pioneer Strategic
Income Portfolios) will not enter into any swap, cap, floor or collar
transaction unless, at the time of entering into such transaction, the unsecured
long-term debt of the counterparty, combined with any credit enhancements, is
rated at least A by Standard & Poor's or Moody's or has an equivalent equity
rating from an NRSRO or is determined to be of equivalent credit quality of the
Portfolio's Adviser. With respect to repurchase agreements, the Portfolio may
invest up to 20% of its assets in securities subject to repurchase agreements.


     For the purposes of  determining  concentration  in any one industry,  each
Allocation  Portfolio will aggregate the amount of investments of all affiliated
Underlying Portfolios.


80% Investment Policy (Lord Abbett Bond Debenture, Lord Abbett Mid-Cap Value,
Lazard Mid-Cap, Met/AIM Small Cap Growth, T. Rowe Price Mid-Cap Growth, PIMCO
Inflation Protected Bond, Third Avenue Small Cap Value, Neuberger Berman Real
Estate, Turner Mid-Cap Growth, Goldman Sachs Mid-Cap Value, RCM Global
Technology, Van Kampen Comstock, Legg Mason Value Equity, Batterymarch Mid-Cap
Stock, BlackRock High Yield, BlackRock Large-Cap Core, Pioneer Mid-Cap Value,
Pioneer Strategic Income, Dreman Small-Cap Value, Van Kampen Mid-Cap Growth and
MFS(R) Emerging Markets Equity Portfolios)

         Under normal circumstances, each of the Portfolios listed above will
invest at least 80% of its respective assets (defined as net assets plus the
amount of any borrowing for investment purposes) in certain securities as
indicated in the current Prospectus. (See the Prospectus for a detailed
discussion of these Portfolios' investments.) Shareholders will be provided with
at least 60-days' prior written notice of any changes in the 80% investment
policy. Such notice will comply with the conditions set forth in any applicable
Securities and Exchange Commission rule then in effect.

         Unless otherwise indicated, all limitations applicable to a Portfolio's
investments apply only at the time a transaction is entered into. Any subsequent
change in a rating assigned by any rating service to a security (or, if unrated,
deemed to be of comparable quality), or change in the percentage of Portfolio
assets invested in certain securities or other instruments, or change in the
average duration of a Portfolio's investment portfolio, resulting from market
fluctuations or other changes in a Portfolio's total assets will not require a
Portfolio to dispose of an investment until the Adviser determines that it is
practicable to sell or close out the investment without undue market or tax
consequences to the Portfolio. In the event that ratings services assign
different ratings to the same security, the Adviser will determine which rating
it believes best reflects the security's quality and risk at that time, which
may be the higher of the several assigned ratings.

                                   -47-




Management

     The Trust's  Board of Trustees is  responsible  for  managing  the business
affairs of the Trust.  The Trustees meet  periodically  to review the affairs of
the Trust and to establish  certain  guidelines which the Manager is expected to
follow in implementing the investment  policies and objectives of the Trust. The
Trustees  also review the  investment  program  furnished  to the Manager by the
Adviser.  Information about the Trustees and executive  officers of the Trust is
contained in the SAI.

The Manager


         Met Investors Advisory, LLC (the "Manager"), 5 Park Plaza, Suite 1900,
Irvine, California 92614, has overall responsibility for the general management
and administration of the Portfolios. Since February, 2001, the Manager has been
the investment adviser of the Trust with portfolio assets of approximately $24.3
billion as of June 30, 2006. The Manager selects and pays the fees of the
Adviser for the Portfolio and monitors the Adviser's investment program. The
Manager is responsible for implementing the asset allocation determinations of
the Adviser and identifying the Underlying Portfolios that are available for
investment by each Portfolio. The Manager is an affiliate of MetLife.


         As compensation for its services to the Portfolios, the Manager
receives monthly compensation at an annual rate of a percentage of the average
daily net assets of each Portfolio. The advisory fees for each Portfolio are:

YOUR INVESTMENT

     Shareholder Information

     The separate  accounts of MetLife are the record owners of the  Portfolios'
shares.  Any reference to the shareholder in this Prospectus  technically refers
to those separate  accounts and not to you, the Contract owner. The legal rights
of you, the Contract  owner,  are different  from the legal rights of the record
owner.


     However,  MetLife is required to solicit  instructions from Contract owners
when voting on shareholder  issues.  Any voting by MetLife as shareholder  would
therefore  reflect the actual votes of Contract  owners.  Neither the Securities
and Exchange  Commission nor MetLife requires any specific minimum percentage of
Contract owners to vote in order for MetLife to echo vote the remaining  unvoted
votes.  MetLife  seeks  to  obtain  a  reasonable  level of  turnout  given  the
particular voting trend. MetLife may use various methods of encouraging Contract
owners to vote, including additional solicitations.  The practice of echo voting
means that a minority of Contract owners may, in practice,  determine whether an
item  passes or fails.  Please see  "Voting  Rights" in the  prospectus  for the
Contracts  accompanying  this  Prospectus  for more  information  on your voting
rights.


Disclosure of Portfolio Holdings


     Shares of the Trust are offered only to separate  accounts of MetLife.  The
following  information  is generally  made  available  on one or more  Insurance
Company  web sites  (including  www.metlifeinvestors.com);  (i) the ten  largest
portfolio holdings of each Portfolio;  (ii) unless the Adviser has objected, the
percentage that each of these holdings represents of the Portfolio's net assets;
and the  percentage  of the  Portfolio's  net assets that these top ten holdings
represent in the aggregate. This information is generally posted to the web site
on or about the first  business day of the second month  following  the calendar
quarter.  The Trust may exclude any portion of these  holdings  from the posting
when deemed in the best interest of the Trust.  These postings  generally remain
until replaced by new postings as described above.


     A description of the  Portfolios'  policies and procedures  with respect to
the disclosure of the Portfolios' portfolio securities is available in the SAI.

Dividends, Distributions and Taxes

Dividends and Distributions

         Each Portfolio intends to distribute substantially all of its net
investment income, if any. Each Portfolio distributes its dividends from its net
investment income to MetLife's separate accounts at least once a year and not to
you, the Contract owner. These distributions are in the form of additional
shares and not cash. The result is that a Portfolio's investment performance,
including the effect of dividends, is reflected in the cash value of the
Contracts. Please see the Contract prospectus accompanying this Prospectus for
more information.
