There are so many viable options that it's hard to pick just one. Off the top of my head Ruger and S&W are hard to argue with, but honestly most any of them in the same price range are good. Pick the one with the features you like.
Just to add, indoors I still prefer a handgun. There are times having one hand gun free is important and it is just easier in close quarters. If I didn't own a gun at all I'd advise handgun 1st. If you already have a handgun then adding an AR is a good idea.
