I'm thinking of getting one of these but am looking for owner feedback on this can. Thanks for any info.
Thompson Poseidon 45?

I considered getting one, but its an "old" design using "wipes" which need to be replaced rather often. It is remarkably short and light, but ultimately unless you are going to try and carry it on a suppressed handgun, I think the longer more modern designs are a better choice overall. There are a fair number of youTube videos out there about it, and its pretty good until the wipes deteriorate.

I have a 9mm Poseidon so it's close but the .45 will be slightly larger and will likely be louder given that it's on a .45. It's a fun can, but it's not going to be the quietest. My 9mm is hearing safe, but gets a little uncomfortable as the wipes get worn. I find wipes last about 20 rounds before you need to replace them.
I wouldn't call the Poseidon an old design. It mixes a short monocore with a wipe at the end. An old design would consist of only wipes and spacers.
Unless they've changed the design, the end cap that holds the threads which attach to your gun is officially a suppressor part so you can't get new end caps to swap the can down to a 9mm. The suppressor is light enough that it doesn't require a booster, so there's no easy threaded inserts that you can swap out.
I bought the Poseidon as my first can and it was fun, but now that I have a full sized can I almost exclusively use the full size can for 9mm. It is easier to use because I don't need to swap wipes and rewet it every 2 mags, but the full size can also ha a more pleasing tone. The full size can is deeper while the Poseidon is higher pitch which makes it less comfortable.
Now I mainly use the Poseidon on a .380. It works MUCH better on a .380 than the 9mm as there's less powder volume (and .380 is already subsonic which saves on trying to find 147gr 9mm) and wipes last a lot longer - about 40-50 rounds before I feel like I need to replace them. It also looks awesome on a Makarov.
They're great cans, but they're definitely specialty cans, not normal use cans. For what it's worth, I think it would make a great can on a defensive weapon if you wanted to use a suppressor on a HD weapon.
One warning though, being an almost sealed design, adding the Poseidon significantly increases back pressure. Though that's more of an issue on a blowback firearm like my Makarov rather than something that has a delayed blowback system like most larger pistols these days.

I think I'd hold off on buying any designs that rely on wipes.
