Well with the introduction of the Chiappa M6 X-Caliber 12 gauge survival shotgun you can elect to leave your standard rifle and shotgun at home you choose to. It shoots 12 calibers of ammunition. The rifle was originally designed to fire a 12 gauge shell and a .22lr, but with the X-Caliber adapter set the M6 can fire up to 12 different calibers including .380 , 9 mm , .357Mag/.38SP , .40 S & W, .44 Mag, .45 ACP , .410/.45colt, and 20 gauge.
The entire system is made of steel except for a foam insert in the butt stock to reduce weight. By pressing a single lever, the M6 can be folded at a hinge point to a compact 18″ that can easily fit in most backpacks.
Do you have plans of taking a shotgun with you when it comes time to grab the bug out bag and get out of dodge? I know that shotguns are not normally part of bug out plans due to their size and weight. Most of us are already packing our handgun and a rifle, no one has room for a shotgun.
