Grandma, too, was saved by a gun. While distracting the wolf with compliments about the size of his eyes and ears, she slowly reached for her weapon.

“The wolf leaned in, jaws open wide, then stopped suddenly,” Ms. Hamilton wrote. “Those big ears heard the unmistakable sound of a shotgun’s safety being clicked off. Those big eyes looked down and saw that grandma had a scattergun aimed right at him.”

Hansel and Gretel got a similar treatment. The story began with them hunting in the woods, eventually bagging “a magnificent 10-point buck,” when they stumble upon a gingerbread cottage where two little boys were imprisoned by a witch.

The siblings climbed through the cottage’s windows and rescued the boys while the witch slept in the next room. As Hansel unlocked their cage, his sister “stood at the ready with her firearm just in case, for she was a better shot than her brother.”

When they returned home the next morning, the children told the parents about the witch and soon, “Villagers, prepared with rifles and pistols, headed into the forest, Hansel and Gretel leading the way.” The witch was locked up by local law enforcement, and then everyone ate her house.

Efforts to reach Ms. Hamilton on Friday were unsuccessful. In an interview with N.R.A. News, she said her versions were “kinder” than the originals by the Grimm brothers because no grandmothers or children were eaten and, despite the guns, the villains were not shot. “The kids do just what they are supposed to do and get an adult,” she said.

Mr. Everitt of the Coalition to Stop Gun Violence compared the modified fairy tales to other N.R.A.-produced fare aimed at young people, such as “Noir,” a program on N.R.A. News starring Colion Noir, a young African-American gun enthusiast who shoots guns and delivers monologues on the importance of the Second Amendment against a hip-hop soundtrack.
