Solid offering from SiCo. Alternatives would be the Hybrid 46 and the Hybrid 46M.
Either the Omega 36M or Hybrid 46 would be a good choice for what you described. I went with the Hybrid 46 for multi-cal/multi-rifle use. Hybrid 46M is the least-useful combination of both IMO.
The Omega 36M papers slightly better for sound than the Hybrid 46, but I'm not sure how much of that is the smaller hole in the end cap - that can account for 1-3 dB of difference on it's own, and each can takes a threaded cap so if you want you can put in the exact diameter of what you're shooting to maximize your attenuation. 46 has a bigger hole, but if 35 cal is your upper limit that's no benefit to you.
Hybrid uses the Bravo/ HUB standard threads, the Omega 36M uses the SiCo Charlie which IIRC is the same diameter but a finer pitch so fewer replacement mount options available.
The Omega has a stellite blast baffle, but both are rated to 10" for 5.56 SBR use (what I consider to be about worst-case use for a can), so toss up there. You won't hurt either of them with 9mm.
I don't consider the modularity of length adjustment as a beneficial feature, just another place in the can that can have a failure. If handgun use isn't one of your uses I don't know when saving 3oz and 1.5" of length would really matter that much. This is why the 46M is the least useful - unless 45 cal pistol and rifle is on the list of what you'll shoot there's no benefit to splitting the can in half.
