What use does have something intended for a last-ditch survival use if in reality you cannot make good use of it? This is especially true in the case of survival guns.
Our body is not like PC hardware, it is said indeed that our
brain is like a gigantic computer but we cannot upgrade it, neither we
can change our operating system and software - our soul - when it fails.
We cannot reinstall things and thus, we have to keep what we have and
survival techniques and knowledge are intended for that.
And among all
survival items there are survival weapons and firearms: these exist as a
last-hope, last-stance, and last-everything under duress and life-
threatening situations. If a survival firearm fails then everything else
fails and we will not be able to boot-up our operating system again,
and there is no possibility to talk with any sort of customer support.
