There are many different uses of guns, and therefore many different reasons people can be attracted to them, or find them useful and relevant in their lives. I bet if you ask 100 different gun guys or gals why guns are a part of each of their lives, you'll get more than a dozen, at least slightly, different answers. I would love to hear your stories.
My own answer has changed over the years, and I think quite a bit, in retrospect...:
When I was 13 and my stepdad put a .22 rifle into my hands (and gave me one bullet at a time - yes, I was Barney Fife for a while), I felt like I took a rite of passage toward manhood; the gun meant something about my own identity.
Later, when I was in high school toward the end of the cold war, I foresaw the day I would fight the Russians. I grew up listening to every word Ronald Reagan said. What I wanted was the biggest badest loudest rifle, and I cherished my DCM M1 Garand. I joined the Military Book Club and assembled quite a library. I read about Carlos Hathcock in Vietnam and probably read "Marine Sniper" 8 times until I could tell every story myself, and took everything as a learning experience, because as Plato said, "only the dead have seen the end of war"; the gun meant a means of defending the common good, and it validated my patriotism.
It was during high school that I also got very political, quoting NRA stats whenever possible in history or sociology or writing classes; although I was the socially awkward kid initially, the gun made me an expert in something and I felt knowledgeable and credible to speak on a subject.
That day I would 'fight the Reds' never came; the Berlin wall fell in my Senior year, and "Red Dawn" became irrelevant in memory. In college, I learned to love the challenge of shooting, and I didn't pick up the M1 Garand or the AR15 as much as the bolt action gun or the shotgun for sporting clays; the gun became a symbol of discipline and skill.
After college, I started to manage retail and had to make deposits at night in some areas of town not known to be exactly crime-free. I didn't pick up the bolt rifle as much, but if I had my handgun I felt completely safe. Without my gun I felt utterly vulnerable; the gun became my foremost means of personal protection and home protection.
Later, when I began to take self-defense classes that acknowledged the role of a defensive gun in a struggle, I was introduced to real world situations that awakened me to how the gun incorporates into self defense, and is not itself the great equalizer against the odds; I realized that my idealism of simply carrying and not preparing very much for self-defense in other ways was simplistic and naive, and the gun became a tool in a far broader toolkit for personal protection. It was with this awareness that I began to offer permit to carry classes.
When I married, my entire focus on the gun was about self-defense. I married into a family of hunters who live in rural areas with little to no crime, and don't carry. My new spouse had some adjustment to make, and I had to be attentive to her feelings as they were not the same as mine, and she felt anxiety about the differences in perspectives ("This is new to me, we had guns for a different purpose. Whenever my dad took the gun out, something died and we ate it"); I took my first deer and the gun became a way to connect with nature and with my new in-laws.
A gun has been with me on my journey in many different configurations, and if you'd have asked me at different stages of my life "What's special about guns to you?", if I would have had the clarity to honestly reflect, I may have given some pretty diverse responses over the years. To some degree, today, the gun means to me all of the things above, though my focus has been in some flux. Whatever our reasons, what brings us together as a 'community' is this object - this thing of steel and wood or plastic that goes boom and blows holes into nearly anything in its path from 0 to 1000+ yards. So, what is YOUR story? What's special about your guns in your life?
