Established earlier, a chimp averages between 2.29 to 3.29 feet in height. Fits for a small creature. Heavy or not, it's a small creature that can grapple a nd medium creature. If the medium creature thought he wasn't going to be harmed, he wouldn't have run. If you listen to the commentator, the human suffered some extensive damage.
I'm not sure that a chimpanzee works as a good example here.
Even if the height of a chimp qualifies it as a Small creature, I think its hands are pretty big. In googling "chimpanzee hand size", I found this -- a life-cast of a chimp's hand:
http://www.boneclones.com/LC-23.htm
According to the description of this item, the hand cast is 9" long. I'm an adult male human, almost 6' tall, and I don't have small hands...but my hands are also about 9" long, from the tip of my middle finger to the wrist joint (which is what the hand cast of the chip is).
So, unless that replica chimp hand is from a particularly huge example of chimpdom, it appears that chimps have hands that are pretty close in size to human hands, despite chimps being only about half the height of humans. (In other words, in the tongue-in-cheek words of billd91, chimps might well have Monkey Grip as a racial feat.)
On the other hand (pun not intended

), all the official illustrations that we've seen of halflings and gnomes certainly makes them appear to be pretty much proportional to humans, just smaller...and that includes their hands.
If someone had a video of a 3-foot-tall primate,
with hands that were proportional to a human's, wielding some human weapon in a competent fashion, that'd be a different story.
