I've got a Backpaker model of the Feather Carbine chambered in 10mm on the way & it should arrive in a couple of weeks.  The takedown feature and use of Glock magazines make it very attractive.  I'll stow it in the baggage caompartment when I fly cross country for use as a survival firearm.  A full G20 magazine of Double Tap 230 gr WFNGCs should deter most 2 and 4-legged predators...  It should make a great home defense weapon as well.
