I really like the machete / shotgun sleeve combo, great idea for a scabbard.
Normally I hesitate towards thinking of a pistol grip shotgun as a survival piece, but in a semi auto format and with a bit of practice that may be quite practical. It has the cosmetics to scratch a post apocalyptic BOB itch or a simple piece of kit to grab and go for hiking the foothills with carnivores about. I dig it.
