I'm a little late to this thread but I didn't see anyone mention the Wiha
brand which also have a slim Nut Driver set with a 7/32" bit in the kit.
When I was refurbing a couple model M here, I invested in this Wiha set,

Easily found on Amazon but not in any local store around here...  especially
not Menards ;-)
