I've written a few stories where very bad stuff happens, and I have had trouble finding suitable magazines to submit them to.
To give you some idea, I'd guess most of you are familiar with Chuck Palahniuk's writing, and perhaps his short story, Guts: http://chuckpalahniuk.net/features/shorts/guts
If you had a story in that vein, and you weren't a well-known author (thus Playboy wouldn't consider you), what magazines would you submit to? Preferably professional rate, or at least well-respected markets.
