Recs for a noob with an Omega 9K?

Hey everyone, I just got my first suppressor a week ago or so, an Omega 9K. So far it's decent on my Kuna when running 147s, and has what I'd call a quieting effect on 300BLK (190 and 200 grain loads, 10.5" barrel AR). I mostly got it for the Kuna because compact and rated full auto for subs and supers in both 9mm and .300blk. I definitely plan on making my Kuna capable of taking advantage of that full auto rating as soon as work takes me back to a locale that hasn't made FRTs/FRSs illegal. I'd also like a unit that will absolutely be safe for firing inside my RV without hearing protection if I should absolutely need to.

All that out of the way, what do you all recommend for my use case? I don't mind having a longer suppressor at this point if it means a drastic difference in decibels. I don't necessarily regret my first can, but I feel like there are better options... any help would be appreciated 👍
