This is going to vary a bit depending on your circumstances. Are you planning on bugging out and if so do you know where you are going? Are you going to be able to store items at your bug out location? I would start by digging around the site a bit and doing some research on each specific area and put together a plan. Once your plan is in place you can decide what your next step is but remember your plan may evolve over time. Personally I have no intention of bugging out however I plan on having a bag around just in case it becomes necessary, this is a decision I came to recently and was not part of my original plan. Once you decide what you're plan is post your questions in the appropriate sub forum and it'll make it easier to get answers to your questions in a timely fashion.
I'm not sure running out and buying a handgun would have been my first suggestion but you could have done a lot worse as far as your selection goes. I kind of swore off Ruger pistols as bulky and heavy with the P series but the new SR series of handguns is suddenly drawing me to them and I am considering an SR-45 as a 2nd floor home defense gun. I'm a firm believer in handguns in a SHTF situation simply for the fact that they are easier to have on your person every waking minute of the day. Spend some time at the range with that new gun and make sure you give us a range report. Welcome aboard by the way, there's a lot of good info and some very knowledgeable people here, I've learned quite a bit since joining.
