Check out this video. It's not me ... but it's a good example of how I kill him everytime except I use a skullmasher instead of pistols to take out his critical spots (I'm also a Hunter, not a Siren).

You just need a decently powered rocket launcher and decent timing to hit him when he's down. I personally use a Crimson Harpoon that I found at some point. Great accuracy, great zoom, and the rockets fly much much faster so timing isn't as much of an issue.
