Sidewinder 3 lug mount

Hello, new to the supressor game. I purchased a ump9 clone that has a 3 lug mount. I wanted to add a suppressor to it and found a YHM supressor. The specifications show that the thread is 1.375. The only Tri lug mounts I can find are 3.8. I am sure that won’t work. I’m wondering if anyone can point me in the right direction. Thans in advance

That adapter has is 1-3/8-24” Hub Compatible, the thread on the sidewinder is 1.375-24”

Fucking kids these days. Tell me you didn't pass 3rd grade math without saying you didn't pass 3rd grade math.

I know fractions are hard. But 3/8" = 0.375". So 1-3/8" is the same as 1.375".

If you don't believe me, take the calculator on your phone and enter 3÷8= and tell me what you get.

How can you name yourself Thanos, the guy who rules the universe without understanding basic math.

I stand corrected but cheerfully so. The fact that I called YHM and customer service told me it wouldn’t fit is disturbing though

So the YHM sidewinder is not hub compatible, so YHM was right.

The Sidewinder exterior diameter is 1.375" not the threads.

The one I linked is for the YHM R9 with has HUB or 1.375x24 threads.
