TUCSON — Gabrielle Giffords looked slightly stricken as she considered the question: Would she feel bad about starring in a political advertisement against her former House colleagues who declined to stand with her on guns? “Yes,” she said, it would be painful.

“Sometimes you have to do things that are hard,” said Mark E. Kelly, Ms. Giffords’s husband, as she tucked herself close to him on their couch. Ms. Giffords nodded, as she often does when Mr. Kelly — as he often does — intuits the many thoughts she is still unable to express fully. “Really hard,” she added.

Ms. Giffords, a former Democratic congresswoman from Arizona, a gun owner, an astronaut’s wife, a shooting survivor and an incipient gun-control advocate, is settling into the third act of her public life.

Her career as a lawmaker is behind her, but so is her role as the fragile, slightly mysterious victim in the months after she was shot point-blank in a parking lot here just over two years ago. Now, she is the face and emotional dynamism behind a new advocacy group and a separate political action committee, Americans for Responsible Solutions, dedicated to reducing gun violence. It is an effort, she said, that gives her “purpose.”
