Apex explains it pretty well on Youtube. Shooting a handgun accurately is all about trigger control. By moving the second stage further back and decreasing over travel, there's less likelihood of pulling the shot. That's not to say you can't pull a shot with the apex sear and everyone is a little different. There is just less chance of torquing the shot when you decrease over travel. You can see if for yourself by watching the front sight while practicing w/ an empty firearm. If you are torquing the shot at all, the front sight will twitch to the right (right handed shooters) when the sear disengages, left for left handed shooters.
The USB is the ultimate striker block. This smooths the overall trigger pull and takes some of the grittiness you may feel with a stock firearm.

Lacking the experience, I will have a gunsmith do the work. I'd rather pay the money and have it done properly and safely.
