The 26-year-old said he’s in good spirits. “I’m just glad my wife did not get hit.”

The instructor did not return a call for comment, but Piemonte said he has been calling him regularly to check in.

“It makes me feel good that he is so concerned,” he said.

The Fairfield County sheriff’s deputy who responded to the scene described the shooting as accidental, The Columbus Dispatch newspaper reported.

Piemonte doesn’t have a gun yet, but was planning to get one this year. He still plans on doing so.

“It was the first time I’ve been shot,” he said. “And hopefully the last.”
