Suppressors Gem-tech MM9 w/LID - what hosts are you running?

[Heronion]

I have recently purchased/sent in paperwork for a Gem-tech Multimount. I will be using this for 9mm handguns. I would like to hear from the owners of the MM9/LID which host you are running with GOOD or BAD results? I have several options for my host at the moment and would like to know what has worked for you guys.

Also, currently have a Walther PPQ that I could get a threaded barrel for.

Thanks,

Brian
