I think anything but laminated safety glass, like a car windshield, would shatter.
As a kid of 12, I was not always the respectful, honorable, clear-thinking individual you have all come to know and love (I'm not wrong about that "love" part, am I?)

Anyway, I had a pocket rocket and a tube of BBs. My neighbor had a garage side door with a pane of single strength glass. I came to know about the "single strength" aspect of glazing when I later had to pay for the replacement of said window.
Twelve shots with my wrist-rocket punched 12 neat little holes in that window. It was waaay cool. At least it was until the neighbor returned home, exited his garage through the side door, and slammed the door closed--at which point the pane of glass disengaged itself from the door and crashed loudly on the cement floor of his garage. He knew exactly where to come for monetary relief (I don't know
how he knew), and my allowance was compromised for the next two months. As I recall, my butt was rather compromised by my dad's belt, too.

So, small rounds and slow speed can punch holes in regular window glass without shattering the glass (until it is disturbed at a later time.) I'm thinking sub-sonic .22 might just work.
