Works perfectly, nice tight fit. They also have the best customer support. You email them any questions, they get back to you literally in minutes and gladly answer any questions, they even sent me a Free O-ring for my suppressor that wasn’t even worn out yet. I just wanted it for a backup. Top notch parts top notch service.

Great product

I have 2 of these in 1/2×28 and 1/2×36; this direct thread hub is a well made product works like it should. But then again, it’s Yankee Hill so that says it all !

Sidewinder M2 9mm , Direct thread 1/2×28 ,1/2×36

Posted by James Smith on Jun 30th 2025

This is my first silencer , I was going to buy one a few years back but the wait was way too long so thankfully now it took 10 days to get approved. I love the mounting options YHM has made and developed. I use this on my M9A3 pistol and my FM9 product AR, both with direct thread adapters and the silencer work flawlessly. Thanks for building great products!
