The rot of statist control of individuals has certainly affected some here very deeply and that is sad to see. Anyone who would actually post that hiking or any other legitimate activity with a gun is somehow ...nuts... should seriously question his own prejudices and the destruction of freedom in the British Commonwealth, during the 20thC.
I HAVE not only hiked, but, actually lived alone in some of the remote and very wild regions mentioned and, quite frankly, a good gun on my pack is a very welcome feeling, as it is in the big seaport city I now reside in, with it's "multicultural" stabbings, lethal home invasions and shootings by gangs of "non-traditional" immigrants, allowed entry by leftist-liberal politicians and gutless cultural traitors.
This particular "gun" is junk and worthless and, btw, a shotgun in a "survival" situation, in most respects, is a poor choice. This is due to the weight and bulk of the ammo and it's relatively poor performance as a defence against aggressive bears, where that is a concern.
A tested, reliable, compact rifle is a far superior choice and for longer wilderness stints, a really good .22 pistol is also very useful. A 20" bbl.ed .308Win. plus an S&W K-22 is a very sound combo in most regions, with the .308 being replaced by a compact .375H&H in coastal B.C.-Alaska where Grizzlies are numerous, huge and sometimes truculent.
This opinion is based on decades of personal experience in exactly these areas, btw, not on what some urban "gun writer" published or posted on the 'net. So, I would not waste .02 on this "Pac-Rifle" pos.
