a low-slung voice

Purring, perhaps, to keep to the car metaphor. Or is it a cat creeping though the undergrowth?

Having said that, this bit comes after they have done quite a bit of shooting at some missiles (at a futuristic and higher stakes equivalent of a paintball club) and she proves to be a fast, sharp shooter that sort of saves our hero's ass. I think that was why my mind steered towards low-slung guns etc. But "knowing" and "roguish" (coupled with her slow, deep voice) do imply sexy to me as well. Thanks again.

There's another image too: one might talk about a 'low-slung car' — one of those cars that seems to 'hug the ground', making it 'sexy' and presumably go faster...

Yep, that was my other guess; now I feel a little bit better about it. Time to go and find something that does not sound ridiculous in Turish.
Thank you.

Even as a native speaker, I am as puzzled as you by this imagery.

Personally, I don't see it as having anything to do with weapons — the idea of a low-lsung gun-belt doesn't really seem to me to remate to a deep voice, especially in a woman; unless, of course, there is anything in your wider context to specifically suggest that.

I think it is more a sort of sexy reference — not only is her voice quite deep, but she uses it, pitches her voice in low, perhaps sultry kind of way. Like wearing a low-cut dress, or wearing jeans low-slung on the hip, perhaps leaving some exposed flesh on her tummy...
This would, I feel, be more consistent with being 'roguish' and to some extent 'knowing' — saying "Would you like a cup of tea?" in a voice that seems to suggest "... or something more?"
