I think you have it backwards. No most gun owners do not own air guns. I would bet most air gunners own at least one firearm though.
I was a life long firearm enthusiast before I was introduced to PCP air guns. Instantly fell in love and spent way too much money on PCP’s
I still shoot both but it is about 85% air guns and 15% powder burners. The air guns are so much more convenient to just go out and shoot. I also like to tinker with them. As long as you don’t get all carried away you can do a lot of stuff yourself on an air gun.
Judge away. We all do it, some of us just don’t mind admitting it
