Don't get me wrong, the Ti-Rant is supposed to be the latest in new tech and it is SUPPOSED to be the next big thing.
Truth be told, I am looking at adding the Ti-Rant to a pistol I am getting, but AAC worked with the pistol manufacturer so the pistol is basically "designed" to function with that specific AAC suppressor.
The Brugger I have seen work with the HK Mark 23 ( the big, heavy daddy of the USP's ) and I know the quality is there. Brugger-Thomat has been in the supressor game for quite a while and their's flat works.
I have not shot, or seen, the Ti-Rant up close, so I don't know. The press has been very positive.
Best bet would be to call AAC, they are VERY helpful, and tell them exactly what you want the pistol to do with the rounds you will be using and field conditions.
