Considering the bullet speed is it worth it? Also do they make any with factory threaded barrels?

Don't know about the pistol but the p90sbr is a great host.

tornado-technologies will thread the existing barrel for suppressor use.

Gem-tech sells a suppressor designed for the pistol and they recommend 2 other vendors that sell barrels for it.

Jarvis makes a drop in replacement for the fiveseven.

Once I pick up my second FiveseveN I will certainly be purchasing a threaded barrel for one of them for a suppressor. That being said, 5.7x28mm is loud. A friend of mine brought a suppressed 11" AR57 to a ballistics gel test that we performed and while you don't have to wear ear pro while shooting it, it's still startlingly loud. We shot SS197, SS190, S4M, Trident, and ProtecTOR out of it. You can get subsonic 5.7x28mm that is designed to be used with a 5" barrel but it only achieves 978fts-117 ft LBS.

I am not sure how much a suppressor would help unless you have subsonic ammo and that kind of defeats the purpose of 5.7?

I have one, it gets the least amount of use out of my suppressors.

The silencerco tests showed the dB range in the low 130s, hearing safe but it's obviously a fast/louder round unless you buy subsonic.
