Just wanted to see how it performs.
I do want to suppress mine but the damn barrel is so expensive.

Does it perform well or lots of hangups?

Running a tornado technologies barrel on mine. Never had a hiccup with SS197. It's loud...more so than my supersonic 9mm suppressed but I am using a 9mm can on it. I'd consider purchasing a .22cal can made for the 5.7 or a .22 can rated for the round.

Run mine suppressed....silencero sparrow...performs very well. no hangups.

I have a Tornado Tech & Jarvis barrel. I use a Gemtech 5.7 can & Spectre II & they work great with subsonic ammo, but are meh with factory ammo due to the ballistic crack. I reload my own subsonic.

I really wanted to like the combo, but wish I spent the money on a different set up. My cans get more use with .22LR than 5.7.

YMMV

My experience as well.

I've thrown 9mm, and .45 suppressors on mine, in addition to .22 cans. I use SS197SR or AE TMJ or subsonics. Occasional failure to feed.

I've got the EFK barrel for mine. Runs like a top with SS198 or SS197. With the threaded barrel and using SS198 my point of impact is 2-2.5 inches high at 15-20 yards with the rear sight bottomed out, with SS197 my sights are adjustable again. Using my Spectre II it suppresses well, definitely takes the bark off when shooting. If I was going to shoot it a lot suppressed I'd buy a larger can just for it. My Octane 45 is much nicer to use on it, a LOT less blowback. When using it I just use the fixed mount 1/2x28 adapter and a Griffin 22 cal. endcap.
