Honestly, the only thing that stopped me from getting the pistol version was that it is bolt action and not lever action. The Flashpup I had, had trouble chambering the pellets I was casting. The two new airguns I got are lever action and chamber the pellets without problem.
A good pcp rifle will fill the niche of any .22 LR, but if you cast your own pellets, you will no longer rely on a supply chain for ammunition. Last I checked, ammo was scarce and overpriced. I used subsonic .22 LR nearly exclusively, so the power difference is negligible. Like .22 LR, it's not something you'd want to rely on to defend yourself with, but what I've got will take down most small game without a problem. They're also really freaking quiet.
@Diptchip Good to know, but there is really almost no condition in which I'd dive air (though it is common for beginner divers who arent certified to use anything but air).. For me ill almost certainly be diving either shallow with nitrox (higher concentration of oxygen than in air), or at depth with trimix (a mix of oxygen, nitrogen, and helium).
That said if you want to get into SCUBA since the entry level that most people stop at is air only it would be a great purchase for you for sure.
