Siliencershop has the AAC Illusion in 9mm:
http://www.silencershop.com/silencers/pistol/aac-illusion-9.html
Price is 676.
Based on this: Build Material 17-4 Stainless Steel, 6061 T6 Aluminum, 7075 T6 Aluminum
I'd assume the baffles are aluminum, though its not listed what they are.

This talks about a stainless steel blast baffel, so I assume the rest are Al.
Couple of ounces heavier than the Ti-Rant, and about the same length for 9mm.
It seems like a Ti-rant, with the eccentric bore aspect to have it sit lower on the axis and thus be able to use factory sights. At 33 db sound reduction compared to 35-38 listed for the Ti-Rant, thought it's longer, it seems the off bore aspect reduces availible can volume and thus supression.
It's an interesting can. I just picked up a Ti-rant 9, so I'm pretty set for this nitche, but for first time buyers, who don't have a 9mm can and just want to be able to use factory sights, it's a good option.
Oh I should know better. I'll but it just becuase ever NFA stamp I get makes little Eric Holder cry.
