It started out as a '9mm Pistol Can', but it is so versatile with the multiple threaded adapters (both fixed and active booster types), that people began using it on rifles from 35 caliber on down with good results, so the manufacturer created an upgrade program to strengthen it (and improve noise reduction a bit as well). Recently I sent mine back to LibertyCans to upgrade it to current 'Mystic-X' specs, and now it is rated for up to 300 Win Mag...!!!
The diameter is 35 caliber, so it covers tons of cartridges, PLUS it is a take-apart can, so doesn't get gunky or hard-to-clean after hundreds of rounds of wax-coated lead bullets (I shoot lots of 38 Special and 357 Mag through it, and it is so light weight that I actually use it on my 22 LR's.
It's not particularly pretty, but as suppressors go, it is light weight vs the cartridges it covers, and being able to use it on pretty much anything you own in 35-caliber-or-less means you will likely not need another suppressor unless you want a really tiny 'rimfire pistol' one (the Mystic-X isn't bad on my Ruger Mk3/45 22 LR though), or a bigger-than-35 caliber one.
I could use mine on all the sub-35 stuff I own:
35 Remington, 357 Max, 357 Mag, 38 Spl, 9mm Para, 380, 7.62x39, 32-20, 32 H&R, 30-06, 308, 30-30, [u[300 Blackout[/u], 7mm Rem Mag, 280 Rem, 6mm, 223 Rem, 222 Rem, 218 Bee, 22 Hornet, 22 WMR, 22 LR, 17 Hornet, and 17 HMR.
Unfortunately I only have threaded firearms in a few of those chamberings., but once I find a gunsmith who can do that (and do it RIGHT), I'll spend the money from time to time to get a few more threaded. Several are Contender or Encore barrels, so they will be pretty easy I'd think; plenty of meat on the barrels, and barrel easy to remove.
So if anyone is looking at suppressors, I'd strongly consider LibertyCans - https://libertycans.net/mystic-x/
(...and no, I don't get any sponsorship from them or anything. I just want them to sell bunches of suppressors, and grow to a bigger company and make more cool stuff...
