by Amendment No. 1 thereto filed with the SEC on May 10, 1999 (as so amended,
the "Schedule 13D"), with respect to the common stock, par value $1.00 per share

2002, following the death of its Grantor, William B. Ruger, the Common Stock
held in the Trust was distributed in accordance with the terms of the Trust
Agreement. While Mr. Ruger remains the beneficial owner of the directly held
Common Stock disclosed in his January 10, 1991 filing, such beneficial ownership
was also disclosed in the Amendment No. 1 to the Schedule 13D and is referenced

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         Not applicable.

ITEM 4.  PURPOSE OF TRANSACTION.

        Mr. Ruger, Ms. Ruger and other members of the Ruger family have
discussed and considered their evolving investment objectives with respect to
their ownership of the Common Stock and have determined that they have a desire
to sell their shares of the Common Stock and redeploy their investment assets.
Mr. Ruger had a preliminary communication with the Board of Directors of the
Company (the "Board") earlier this year to determine if the Board would be
willing to facilitate this process, but the Board indicated that, at that time,
it believed the best course for the Ruger family would be to sell the shares of
Common Stock under Rule 144. On April 5, 2006, the Reporting Persons engaged
Stephens Inc. to act as their advisor in analyzing strategic and financial
alternatives in connection with their ownership of the Common Stock.

        In addition to the foregoing, the Ruger family monitors the performance
of their shares of Common Stock. The Ruger family intends to continuously
evaluate the Company's business, financial condition, operating results, capital
structure, management, stock market performance, competitive outlook and other
relevant factors. Depending on such evaluations, the Ruger family may, at any
time and from time to time, purchase additional shares of Common Stock or may
dispose of shares of Common Stock held by them.

        As part of such evaluations, the Ruger family have and may in the future
seek the views of, hold active discussions with and respond to inquiries from
members of the Board, officers or representatives of the Company, stockholders
of the Company, and other persons regarding the Company's affairs and strategic
alternatives, including a possible sale of the Ruger family's shares of Common
Stock or other strategic alternatives of the Company.

        Except as otherwise provided herein, the Ruger family have no plan or
proposal with respect to the Company which relates to or would result in any of
the matters listed in Items 4(a)-(j) of Schedule 13D.

        (a) Mr. Ruger is the indirect and direct beneficial owner of an
aggregate of 5,322,000 shares of the Common Stock, representing 19.77% of the
issued and outstanding shares of the Common Stock. These shares consist of
4,272,000 shares of the Common Stock held by the Partnership as to which Mr.
Ruger, together with Ms. Vogel, is the indirect beneficial owner, plus 800,000
shares of the Common Stock he owns directly, in addition to 250,000 shares of
the Common Stock subject to options, currently exercisable, which he also owns
directly. Ms. Vogel is the indirect and direct beneficial owner of 4,487,500
shares of the Common Stock representing 16.67% of the issued and outstanding
shares of the Common Stock. These shares consist of 4,272,000 shares of the
Common Stock held by the Partnership as to which Ms. Vogel, together with Mr.
Ruger, is the indirect owner, plus 215,500 shares of the Common Stock she owns
directly. Ruger Management is the general partner of the Partnership and as such
is deemed to be the indirect beneficial owner of 4,272,000 shares of the Common
Stock held by the Partnership representing 15.87% of the issued and outstanding
shares of the Common Stock. The Partnership is the direct beneficial owner of
4,272,000 shares of the Common Stock held by it representing 15.87% of the
issued and outstanding shares of the Common Stock.

Common Stock as to which he is the beneficial owner. Ms. Vogel is entitled to
direct the vote of 215,500 shares of the Common Stock as to which she is the
beneficial owner. In addition, the power to vote the 4,272,000 shares of the
Common Stock held by the Partnership is beneficially shared by the Partnership,
Ruger Management, Mr. Ruger and Ms. Vogel. However, Mr. and Ms. Vogel each own
50% of the capital stock of Ruger Management. As a result, they have the sole
power to direct and control the activities of Ruger Management which, in turn,
has the sole power to direct and control the activities of the Partnership,
including voting the shares of the Common Stock owned by the Partnership.

        (c) Ms. Vogel sold 156,000 shares of the Common Stock on May 12, 2006,
in the open market pursuant to Rule 144, for an average price of $5.90981 per
share of the Common Stock. Ms. Vogel also sold 28,500 shares of the Common Stock

         TO SECURITIES OF THE ISSUER.

        Mr. Ruger and Ms. Vogel each own 50% of the capital stock of Ruger
Management, which is the sole general partner of the Partnership.

        Except as described herein, none of the Reporting Persons have any
contracts, arrangements, understandings or relationships (legal or otherwise)
with any person with respect to the securities of the Company, including but not
limited to transfer or voting of any of the


                                       8

calls, guarantees or profits, division of profits or loss, or the giving or
withholding of proxies.
