I wish to respond to the article concerning the effectiveness of the Maryland Handgun Roster Board {"Effectiveness of Gun Law Is Challenged by Both Sides," Metro, Dec. 7}. Michael A. Pretl, attorney for Marylanders Against Handgun Abuse, continues to complain about the board's being inconsistent and not having specific criteria by which to judge handguns.

As the former co-chairman of the Maryland Committee Against the Gun Ban, I know the truth is MAHA wrote the law that established the board; it's their law. Now that it is not banning enough guns to satisfy members of MAHA, they want to change it.

Three people who campaigned vigorously for passage of this law sit on the board, including a member of MAHA. Not one person from the Maryland Committee Against the Gun Ban sits on the board. The National Rifle Association representative did not participate in the referendum drive.

Since MAHA has had a seat on the board from day one, why has it waited almost two years to complain about the board's deliberations. Since MAHA's own man sits on the board, it can't complain that it didn't know what was going on.

It sounds to me like a case of sour grapes and proves that MAHA wants to ban as many firearms as possible, not just Saturday night specials. SANFORD M. ABRAMS Silver Spring
