not shocking, apes and monkeys have insane power to weight ratios, chimps can literally disembowel you with their bare hands.
i love how they say it can withstand a 9mm round, because a 9mm round imparts SOOOO much kinetic energy. 
the windshield on my car can withstand a 9mm round.
Yep Chimps are insanely powerful and Gorillas would rip Chimps limb from limb with ease, here are some more accounts of brutal Chimp attacks below describing how powerful these animals are.

Texas man tells story of fatal chimp attack
His friend's hand was a mangled mess — most of it was gone. The station wagon had stalled after the driver desperately tried to ram through a gate. And now the chimpanzee that had attacked them on an isolated mountain road in West Africa was coming at them again.
What was supposed to be a day of sightseeing Sunday at the Tacugama Chimpanzee Sanctuary had turned into a moment that will forever be seared into Gary Brown's memory?
"I knew I was going to die, but I didn't want to die running," said the 51-year-old Texas man, who was working as a contractor in Sierra Leone.
Inside the Peugeot station wagon were Brown, two American co-workers, Melvin Mammah, a friend Brown had met in Freetown, and Issa Kanu, who had been driving them back and forth to work and other places during their stay. Brown was in Africa working for a telecommunications company at the American embassy, said officials with Spectrum Solutions and Caddell Construction.
Brown, who returned home Tuesday night, didn't know at the time that more than a dozen chimps had escaped from the 100-acre sanctuary on the outskirts of the capital of Freetown. And he didn't know chimps would attack people. When the chimp had appeared on the road in front of them, he had fished for his camera, eager to get a snapshot.
That's when the chimp charged, Brown said.
He said it tore off the side mirror and broke through the back windshield. "It was like the glass wasn't even there," he said.
Brown, said he's 5-foot-9 and weighs more than 200 pounds, and the chimp probably outweighed him.
"He had every bit two-inch fangs, and he was screaming like a banshee . . . when he was charging us."
Mammah fought the chimp off, but not before the chimp bit off half of his hand, Brown said.
They wrapped up Mammah's hand and drove forward, trying to outrun the chimp, he said. Then they came to a steel gate. Kanu rammed it, and the gate opened, but not enough to get the car through, he said.
The car stalled, its front end crumpled. Reverse didn't work, so they got out trying to push it backward so they could turn it around, Brown said.
"He was charging again, coming up the road," Brown said. "When we turned around, we all dove in the car."
Kanu tried the key again. The wagon started, and he tried to drive through the opening in the gate, but it became wedged into the opening, Brown said.
The chimp "went across the top of the car, and that's when . . . it was just a flurry trying to get away from it. Melvin got pulled out of the car by it."
When he jumped out of the car, Brown said he heard Mammah screaming for help. Everyone else in the car had fled, Brown said.
Kanu who had fled with the huge crazed Chimp in pursuit, tried to outrun it in terror and sadly was easily caught and killed. Later they would see the awful result of this terrible mauling by the huge animal
The Chimp reappeared out of the bushes
Brown said he used to work as a telephone lineman and was used to facing down angry dogs. He spotted a large tree limb.
"I grabbed it and I just started to charge around the car to go help Melvin," he said.
"I believe it was God who got me through it, he turned my fear into anger."
The chimp charged him, he said, and he drove the end of the limb into its throat, then chased it away.
Mammah looked like he was bleeding to death but refused to allow Brown to carry him, Brown said. He said he looked for the chimp and spotted it in the jungle, watching him. He could hear chimpanzees screaming all around them.
Brown said he helped Mammah hobble down the road, where a military patrol found them and took them to a hospital.
Later, a van pulled up with Kanu's mangled body in the boot of the car. Brown said he thought the other Americans were dead too.
Kanus both hands and feet had been ripped off as well as his jaw torn from his head
"I can't get it out of my mind," he said.
Mammah lost all but two fingers on one hand, but is recovering in a Freetown hospital. The two other Americans escaped safely to the American Embassy.
The other Americans all survived
