Most gun owners in the US don't use them a lot.
TL;DR - Fire Extinguishers
In a case study of Danoff, it depends on which guns you're talking about, and what constitutes a use.
I have 6. It'll itemize:
1) Revolver handgun
2) 9 mm handgun
3) M1 garand (for the uninitiated this is a
semi-automatic rifle from WWII).
4) M1 carbine (another semi-automatic rifle from WWII).
5) Double-barreled shotgun, well over 100 years old
6) Reproduction civil war black powder musket.
All of these guns are in a long gun safe. So let's run through them really quickly. Do I
use the black powder musket? Well, no probably not. I don't know how to load it, I don't own black powder, I don't own a musket ball. I'm not a civil war re-enacter, I have no interest in shooting a musket. As you might have gathered, I did not purchase this gun, it was a hand-me-down. I don't know that I'm dying to sell it, but I'm also not dying to use it. I also don't think it can hurt anybody, because I imagine that if I took a poll of the 10,000 people nearest to me, there might be like 1 that would actually know how to load and fire it. I wouldn't be surprised if none of them did.
Do I use the double-barreled shotgun? Well again, probably not. That one is really ornamental, and it does a bad job of that in my safe, where nobody can see it. The last time it was fired was approximately 80 years ago, and it was so old at that time that it broke itself (one of the hammers shattered). At this point firing it would probably further break it. I don't own ammunition for it, and I don't consider it to be much of a liability. I find it interesting because it pre-dates gun serial numbers and it's one of the earliest gun-guns (as opposed to muskets). So really more of a collector's item. Am I
using a collector's item? Uh... probably not as a collector normally would. I don't display it.
How about the M1s? Do I
use the M1s? I'll admit that I don't have ammunition for them and don't know how to load them (apart from my experience watching the CGI guy do it in Call of Duty). Once again, I own these more like a collector would. I don't display them, but I find them interesting and I like that I own them. I also don't think they pose any risk to anyone. Once again, I don't own the ammunition, loading them is not exactly super straight forward (so it's not like a toddler is going to do it, without ammo, on accident). And they're in a safe.
So that's 4 guns down. Let's get to the real ones.
Do I
use the handguns? Well I have fired them both recently. I'd say within the last 2 years. I try to take them to a gun range and keep skills sharp periodically. I find that I forget a few little details here and there if I don't do that. I also like to exercise the spring in the magazine of the 9mm a little and make sure that it actually performs its reload function. But I do not particularly enjoy shooting at the firing range. It's expensive and loud and kinda uncomfortable. And I really despise jams, which the 9mm will do if you're firing cheap ammo. I go fire these guns regularly because I consider it to be my adult responsibility to be proficient and accountable for my safety and the safety of my family.
In a sense, I use these guns every moment that I'm at home. The represent the ability to defend if needed. I also own an emergency kit that includes some food and water in case of a blizzard. I don't
use the emergency kit, I've never
used it. But I'm prepared for an emergency. So I
use it to be prepared. I also own fire extinguishers. Now I've never had my house on fire. But in a very real sense, I use those fire extinguishers every day to be prepared for one. If you took my fire extinguishers away, would it affect my day-to-day life? Well not in an outwardly visible fashion, but I'd be less prepared, and I'd stress that a little. I'd feel less in control of my life and circumstances, irresponsible, and if the worst should happen, and a fire starts, I'd feel criminally wronged by the government that prevented me from being prepared.
