Outer Dark is really good, I would recommend that as well as Child of God. Both are some gritty dark tales in the south. If you are looking for a bit of a different McCarthy tale, check out Suttree when you get a chance - it has since become my favorite McCarthy novel or on par with Blood Meridian.
Those are all great as well and I was recommended those through Amazon after only reading MCarthy. If you ever need more, feel free to PM me, I pretty much only read this niche genre.
Check out Donnybrook by Frank Bill. It has a full cast of degenerates and violence on nearly every page. I absolutely loved it. It's not quite the violence you were thinking about (there is one hitman in it though), but I still think you will enjoy.

I loved both of those books. Donnybrook is another book about f*cked up white trash, that I highly suggest.
