I am getting an obsidian 9. Is there a good threaded barrel for standard 365. Will using the modular can in sort configuration work reliably on my little Sig?

I am no expert, but I just wet through the process for my first suppressor and was originally looking at the Obsidian.

Input from others led me to change my mind (several times) and ended up ordering the YHM R9.

You might want to pursue my thread in this section if you haven't already.

Sig makes a threaded barrel for the 365 which would probably be the first one I would look at. And they smartened up and its 1/2-28 and not metric.
If you have already ordered the obsidian so be it, if not there are probably better choices.
No first hand experience but since its so small I would imagine its a bit finnicky suppressed, you can probably do an internet search and see what others say with practical experience. I would probably try to go as light as possible on the suppressor given the size of the gun.

I appreciate the great input. One thing I like about the obsidian is its modularity.

I got a threaded barrel from SilencerCo for my Sig P365 Macro.

I had a Ballistic Advantage threaded barrel for my P365. I had no issues with it with several different suppressors. I ended up selling my P365. I don't know what I did with the barrel. Probably in my locker at work. lol

For those that put Suppressors on the 365, is it worth it?

i can't answer your exact question as I've not done a 365 but I have done a whole bunch of others, but I am willing to say after a number of tries on suppressed pistols I go... yea possible but not really interesting.

I haven't shot this setup yet, P365 Macro Tacops with a Spectre 9. I've temporarily escaped the Texas heat for cooler air in the Colorado mountains and didn't bring it with me. I'll report back in about 10 days. I found this host used on a local gunboard, I think it's going to work out nicely. The Tacops comes with taller suppressor height sights, that barely clear the can. Will it be as good a host as a P226? Probably not, but I hope fun to play with.
