Fair enough. One attraction is the low sound-level of airguns. That and the many other attractions have been thoroughly dead-horsed elsewhere.

That being said, I have decided that a very excellent option that sort of combines what I see as the advantages of airguns and regular firearms is the CB long cartridge in a .22 rimfire carbine or even long-barreled semi-auto pistol (more portable and packable). There's a high-quality short-barreled CZ bolt-action scout type or youth .22 RF rifle with an adjustable trigger (a very excellent feature of the older Beeman R1,R7, R9 etc airguns) that I think would be close to ideal with the CB longs for many purposes. Until then, I have an old Winchester 69A and a newer Marlin 60 that will do.
