Agree with the above - a gun is absolutely a last resort. If you can quietly call "911" as you shelter in place with a perp unaware you're there, that's the best case but it may not be realistic in all situations - and every situation will be different. If you buy a gun, you'd best be prepared to use it. Get something you can extract and use simply and as second nature. Guns with complex safeties aren't great - if / when a situation happens were you need it you'll be stressed, maybe not thinking clearly, possibly in the middle of the night, half asleep, with poor lighting, etc. It needs to be so suing you can use safely in your (near) sleep.

Also, get one now if you're considering it. As time goes on the laws, restrictions, etc. only get more onerous and an option you have today might not be there on a year or two. Just something to consider.
