I think the forward serrations are handy.
You can rack with rear serrations from behind (hand is behind the slide). In case of an AD there, the slide gets a big bite out of your hand. Not likely, i know, but hey, it could happen.
When racking rear of slide from the front, your weak hand covers the ejection port. If you do it this way with a full chamber, your hand could bounce the brass back into the chamber and jam. Not likely either, and annoying at worst.
Racking on the front serration with hand toward the front puts your weak hand in front of the muzzle. Bad.
Or you could grab the front serration with your hand to the rear, covering the top of the slide. No risks, and a good grip. Perfect!
