I currently have the following pistol silencers:

Octane 45HD
Revolution 9

I mainly use the 45hd for 45 and 10mm while I use the Revolution 9 on sub guns and all my 9mm pistols.  I bumped into the Odessa at a Gun Store and thought what a cool setup it would be with 4-7 baffles on smaller pistols for backpacking, etc (think P365 or g43).  I can use my Revolution 9 in the K config but it's still fairly bulky in those applications.

Think i should stick to what i have or is there anything you may recommend as an alternative?

You may have better reply if you post your question in the Armory section.

If I were into collecting tax stamps (I'm not) if I had a can for 45/10 and one for 9 and smaller pistol calibers, I'd possibly look at a suppressed upper for a Ruger Mk II/III/IV or a integrally suppressed barrel set up for a Buckmark.

But then, I shoot a lot more rimfire than I do centerfire just 'cause economics.
