Maloney, a former Marine who is in his mid-20s, was participating in a training exercise when a stick of dynamite exploded in his palm. He lost his right hand.
The Bethel Park, Pa., man was the first person to get a hand transplant at the UPMC.
Maloney's surgery was one year ago Sunday, and he said he feels good.
"Drive down the road, and got a girl in my truck, I can hold her hand while I'm driving. It's pretty nice, you know, to feel normal again," he said.
Pollock is well on the road to recovery. Just three weeks after the historic operation, he is feeding himself.
He said he remembers the moment when he woke up after the surgery.
"They were telling me 'move your fingers,' and I was like, just doing that," he said. "I was, like, amazed ... it happened so quick."
