The New York City public advocate on Monday asked federal regulators to investigate whether the gun manufacturer Smith & Wesson had made adequate disclosures in its financial statements.

In an eight-page letter, the public advocate, Letitia James, said the Securities and Exchange Commission should examine whether Smith & Wesson misrepresented or omitted information about how often its products are involved in crimes and what it has done to keep its guns out of the hands of criminals.

Shareholders would want to know whether Smith & Wesson faced heightened regulatory scrutiny or significant litigation risk, Ms. James said in the letter.

Nearly two weeks ago, a terrorist attack in San Bernardino, Calif., left 14 people dead and provoked a fresh outcry about gun violence in America. It also is the third anniversary of the shootings at Sandy Hook Elementary School in Newtown, Conn., where a gunman killed 20 children and six adults.
