For a thread on .22 can, I'd take a hard look at the Liberty Regulator. Liberty isn't typically a go-to, they make monocore cans mostly for hunters but their .22 cans are just hot shit. I have two and another integral from them. The Regulator cost half as much as the Essence at $300-ish and weighs 1oz. more (Essence was already one of the top 3 lightest cans made at the time) and is one of the quietest cans made (noticeably quieter than the Essence, which was a $600 can and very quiet) only 3 parts and no tools to takedown, no FRP (Essence had a tiny bit) and with 1cc water it's basically silent and I had to dedicate this suppressor to my pistol with the least action noise in order to get the most out of it. If you can't honestly say that about your .22 can, then you'd do well to heed this.
That said, I still want a TBAC .22 can too. But the Pinnacle 2 integral I used to build a Kidd 10/22 has no other noise than the "click" of the action really. Spooky quiet for sure. And accurate. I wish I'd gone this route in the first place because I sure use it more than any of the others, it's as much fun as the M2HB! About $2000 for everything, but if you have a good rifle to start with then the barrel is only like $600 or so:
I have a Liberty Mystic X, it's the one "multi" can I have but I only ever used it on a 9mm. I didn't wanna spend much on it, I don't use a can on a pistol much, they're just too long and heavy. I'll probably put that one on a small 9mm rifle some day. But the Sico Omega 9k? That one's the titties for 9mm pistols IMO. It's short, it's not gonna be spooky quiet, none of the pistol cans really are IMO/E, but it does take down the boom to reasonable levels and the can is small so it doesn't upset the weight or length of the pistol so much. It's great on the G26, makes it about the same size as a G17 give or take.
I'd avoid using .45 cans on a 9mm. 9mm generally suppresses better and it'll do a better job with a "tighter" can. If most of your stuff is 9mm, just go that route. It's what I did. I have a .45 and a 10mm I'll never suppress. And I almost never use the 9mm can FWIW.
For the rifle, I'd get the TBAC 30 Ultra 9. It's light and it's quiet. The 7" is the best all around one I guess, but if you can accommodate the 9" I'd get it instead. Later if you want shorter, just get an Ultra 5 and go that route. It's what I did and each can has it's merits. The 5 is no slouch either BTW. The 6.5 dedicated cans are nice, but the 30 will work here just fine --you can always dedicate one later in 6.5 if you like, but IMO/E it's not necessary. You can use .223 through it too but just know that larger bore cans generally make a deeper, throatier sound with smaller bore rifles. In some cases the larger cans actually suppress the smaller rounds better than the dedicated cans, but I'd still aim at getting dedicated 5.56 cans later on if it suits you. I started out wanting the same 3 cans you did and ended up dedicating cans to most rifles.
You don't wanna use the Ultras on say, an M4 that's gonna see lots of sustained, rapid or full auto fire. I think they make one now in SS that'll do that in 5.56, and then there's the Saker in 5.56 and 7.62 that's made for that kind of abuse.
You can go a lot of routes, I'm just laying out what I did and letting you know what works best. I like to stick with known companies that have been around a while and have a good following. I have others, but I didn't recommend them for various reasons. However, if you can score Sico Saker cans on sale and they suit your application, then that's another solid contender for rifle cans, quality for cost. And you could probably get a 5.56 and 7.62 on sale for same price as one can, PLUS a free .22 can from Capitol Armory right now if they're still doing the BOGO deal. That'd be a damn good start. I just got two sakers there for $1000, plus mounts plus adapters made it $1300 (but missed the BOGO deal by like a week, not that I really needed it). Killer deal I couldn't pass up to suppress two 5.56 rifles with quality cans.
Elite Iron is another solid contender I'd look at that offers precision cans and hard use cans made of SS. The SS keeps the costs down. He makes these for alphabet soup agencies and they're solid suppressors. I use 'em in .50BMG and I have one in .338LM.
Good luck!
