I can think of No Reason whatsoever that a 10 year-old kid should be roaming the neighborhood, or even his backyard with a handgun and loaded clip. How many time have we read that (fill in the blank) was doing (fill in the blank) with a firearm and didn't realize there was a round in the chamber, thus resulting in the death of a friend or relative. Bottom line is Granddad needs to secure his firearms - period; hopefully there's a lesson learned there. Kid needs to attend mandatory firearms safety class - it will actually be fun for him in addition to being educational. Plus, ten year-olds can very well understand the concepts of firearm safety, use and maintenance. This mishap can easily be a learning experience if handled correctly.
