Decisions decisions ??????? the husband using wifes account?

I'm in the market for a gun but i have real problem , money and not just wanting one gun i wont / need two guns .... i live in a ruff neighbored and cant make up my mind if to get a handgun / springfield armory xd 9 mm or a tactical rifle/ rem 700 sps tactical 308 . one for home defense one for hunting . but at this time( one )is all i can afford and to note i already have an sks with a tasco stock and 1 thirty round clip and 1 forty round clip pluss hundreds of rounds for those mags . not the best idea for home defense considering i live in an apartment and not the best for a real all round hunting rifle that will drop most animals in north-america within at least 350 to 400 yards . its more of a combat / urban warfare rifle that fires rounds that penetrate plenty of materials . so seeing that all in all i have a gun (sks) that does do the job of either roll with the right type of ammo the idea of the 7.62x39 going through a wall and accidentally killing someone that is innocent and also not being able to really reach out and touch something / animal puts me in a bit of a conundrum . what to do ? and let it be known i do have a lot of gang members living all around me plus lots of homeless people all over the place and i have a wife and child . my concern is that the way things are going in the world would the sks fill most of that roll or to be honest if the $h!t hit the fan i would need a rifle that would put food on the table .the sks would do the job of protection if that was the case (worst case scenario) and drop animals too. so what should i do ? buy the hand gun or the rifle . i want honest opinions , which one is worth its weight in gold ? plus i do know that some time down the road i need to buy some version of a 22lr for small game but that is down the road .
