While you can achieve really good and even excellent results with some of today's precision air guns, I feel as though the slug came before the slug gun and that we are still awaiting its arrival. Perhaps there is so much money to be made trying to find the right slug, barrel, regulator pressure, hammer spring tension, barrel tension, moderator etc that producing an air gun specifically to shoot slugs properly, would be economically damaging to the sport overall. We have the ability to do so and relatively inexpensively if we want to, so why not do it? Why create this rabbit hole and the supply enough lubricant to allow any unsuspecting, would-be slug slinger to not only fall but willingly dive headlong into said sink hole? For it truely can swallow all who venture too close, even just to peer over the edge - innocently enough. By design? Say it isn't so! Is there any light at the end of this tunnel? Even a black hole has an exit as it were... .
