Whenever I visit my in-laws I tend to bring my p365 in case we're caught up in some sort of emergency where I want to be able to conceal carry and then whatever other pistol I think my sister-in-law would enjoy shooting in case we have time for a range trip.
Whether you bring a long gun or not depends to some extent whether you have anything that's legal in the state you're going to. I don't usually bother but if we were going to see them in the near-future then I'd consider my Maverick 88. It'd do just fine for most realistic encounters and definitely the most practical of my Cali-legal guns, the 1886 and Garand would have a lot more style though.
