I have pretty large hands, but I would characterize the grip on the VX-5000 stock as somewhat thick. However, it's near vertical, so it moves your hand closer to the trigger. Plus, if you're target shooting off a bench or bipod, you're not using a death grip on the stock anyway.
The VX stock's forend is totally flat, though it does have a cool-looking oval cutout machined in the center of the bottom to hollow out the forend and reduce weight. The skeletonized forend gives it a cool, "high tech" look. The perfectly flat, wide forend sits solid as a rock on a rest. It's not a hunting stock for certain. The buttstock shape is perfect for target shooting with a scope. I don't think a more solid platform for a .920" barreled 10/22 exists on the planet. It's kinda expensive, but when you consider that the entire front end of the stock is CNC machined from aluminum bar stock, it's not really expensive for what you get.
