US Air Force survival gun?

One of my secondary duties was oversight of our Global Survival Kits
carried in our F102s. Since we sometimes crossed the northern US
border (even in winter - brrrr!) the contents had to meet some
stringent requirements. One of the pilots said all he needed was a
dime for a phone call. (Long time back!) I laughed and replied 'And if
you break a leg on landing in your chute at night?' Lots of empty
territory up there in the Northern spaces. We had the M6 - ISTR along
with a 50-round pack of 22 Hornet and a dozen 410 shells. The M6
wasn't as fancy as the LW gun but a) it worked well and b) the USAF
needed a LOT of them, roughly one per crew position, at a guess around
10,000. And it didn't weigh a dozen pounds as most drillings did (do).
