ARs are very useful for a variety of threats, but not a realistic home defense option for many of us living behind the iron curtain of ignorance/stupidity in UNSAFE new yorkistan. I have done a lot of research and field testing, including publishing a bunch of stuff in various gun mags, but slugs wouldn't be my first choice for go-to home-D shotgun ammo. Some of the low recoil 00 loads from Federal (flitecontrol wad) and Hornady (versatite wad) are outstanding, produce super-tight patterns at typical home-D engagement distances (10-to-30 feet) and the reduced recoil allows for lightning fast follow-up shots if your 12-gauge is set up accordingly. Federal's LE1B load (15P, #1 buck, 1100 fps) is another interesting alternative, but is extremely hard to find. #4 buck is also a nice option and I just picked up a bunch of Federal's PD156-4B to field test and pattern for an upcoming product review. It's lower recoil at 1100 fps, with 34 pellets, but it's not flite control, so the pattern will be "expansive", probably following the usual 1" spread for every yard downrange. Will post some pics of my assortment of 590A1/590s later, but I'm fighting a story deadline for this weekend.
