Sig MPX washer?

I have an MPX and want to put a suppressor on it. I was told that it should have a ring or washer or something so an Octane 45 cal would fit correctly. Does anyone have any idea what I should have so the suppressor mounts exactly to the barrel?
Thanks
Thom

Hey thom - I ran a Silencerco Omega 9k on that MPX. I forget the thread pitch but will try to look it up, left hand 10/24 I think, but has been awhile. I believe you just need the correct sized piston or even a 3-lug.

Thread pitch on a Sig MPX is 13.5x1LH.
Direct thread with a SilencerCo Alpha mount (which they don't make any longer but you can still find them online, part # AC1526), or mount a tri-lug onto the MPX barrel and put the tri-lug mount onto your Octane 45.

I have an MPX and I got one of thi in lead we trust barrels with the tri lug built into it. I use a dead air wolf man and it is amazing. However on my MCX I have a different flash hider on it and that did require the adapter so that the hider would tighten down properly.
