MPX K Recommendations

[Bobgoesoutdoors]

I’m pretty new to suppressors and have limited knowledge. Feel free to talk to me like I’m a first grader.
I just recently got a 30 cal can but have yet to shoot it. It’ll get most use on my AR, but I’ll pop it onto my 6.5 CM bolt rifle for some long range/hunting too. My biggest thing is minimizing cost- I just also got my Sig MPX K and 8” hand guard a week or so ago, and just as I typed that a moth fluttered out of my wallet.
I’m all set up for direct-threading my 30 cal can (AB A-10 Warthog, $30 thread adapter). It seems like that may not be that easy on my sub gun. I’ve seen quite a few mentions of tri lug adapters but I’m not sold on that route yet. I prefer a solid mount over speedy installation and takedown, which seems to be the tri lug trade off. Am I mistaken on that?
If my goal is a low price tag and solid mount, what should I go with? Also probably wouldn’t hurt for it to be low maintenance too, since I don’t know what the heck I’m doing.
Thanks in advance!

Generally speaking, you'll want steel. Shorter barrels have a lot more pressure and gas-heat than longer ones, so titanium cans in general would not be a good option. And there's no problem at all with direct-threading a K can on an SBR. It actually removes a lot of problems, and is generally lighter. If you're worried about it unthreading, just put a little vibratite on it. If you're looking for a durable, K-sized can that's on the cheaper end, the Polonium K is a pretty good option.

Does your MPX K have 1/2”-28 or M13.5x1 left hand threads? Seen them go both ways.

If 1/2”-28, the Shiv 9mm would be a solid option. Cheap ish, direct thread, light (2.5oz). Just thread it on and go.

If M13.5x1 LH then something like an SiCo Omega K or YHM R9 with a direct thread adapter would work well and not break the bank.

It almost sounds like you want to run the AB A-10 30 cal. suppressor on the MPX K. If this is the case, please remember that a 30 (.308) cal. can would be very unsafe on a 9mm (.355) firearm. If this is not the case, please ignore this post.

Head-slapper moment - OP, the Polonium K I recommended will most definitely not work on your 9mm subgun. Somehow what I read was that you were using a .223 pistol/SBR. Disregard.

Zero Fox, that Shiv looks really interesting. Haven't had any experience with these newer 3D-printed cans, but on some of them I see they have a lot of tiny vent-holes in the front. How are these things doing with high-round counts, in terms of fouling? I'd be concerned those tiny holes, and whatever the design internally is of the baffles/channels, would be more susceptible to getting clogged and becoming less effective with fouling at a faster rate than traditional designs. Any experience or info on this?
