i shoot 410 out of a bond arms 410/45lc derringer, savage m42 22wmr/410 o/u, h&r single and khan folding single. my b.a. is an edc, loaded with handgun specific defense ammo. the khan folder is a nifty trunk gun, unobtrusive in a gym bag, useful in handgun-unfriendly locales. ammo is light, weight is light, recoil is light (in a long gun). 410 is the 22lr of shotguns for protection: easy to shoot, bigger rounds are better stoppers, but nobody will volunteer to stand in front of either a 410 or 22.
