Have you heard of this? My question is how long does the CO2 cartridge last? I have a Colt SAA BB gun made by Numarex and it takes a CO 2 cartrdge. That cartrdige doesn't last very long. Maybe a couple weeks whether I shoot it or not. If you're carrying one of these Byrnas will you depend on the CO2 cartridge let alone the projectile itself? Interesting alternative for carrying a real firearm though.
