Was talking to my local gun shop owner about getting a suppressor this year - and he suggested a local manufacturer which has an .45 ACP suppressor that uses adapters which threads in to the barrel end of the suppressor allowing caliber changes of 9mm - .40 and .45
He says some suppressors DO NOT allow this functionality but this manufacturer does.
Ever hear of such a thing? (Pun??) He does admit that with the .45 suppressor used on a 9mm there is a bit more noise released, but not remarkably so, and my hearing is so shot... I will never hear the difference.

Just realized I put this here, and not in pistols.... sorry - mods.

You did right, it could be for a carbine. ;D
Rastus and a couple others are the suppressor guru's but when ever I hear "multi caliber" I think, one size fits no one right.

From my research, a suppressor will work best in the maximum caliber it's designed for. It will work for smaller calibers, but not as well. Also, bigger calibers may require a bigger, heavier, suppressor. So, a .308 suppressor will work on a .223, but not as well as a .223 can. The .308 can may also weigh more and be bigger.
I know that Yankee Hill, a large suppressor maker, makes adapters allowing caliber changes, or more accurately, using one can on guns of different caliber. Remember that the barrel outside diameter is what's important, not the size of the hole in it.

I thought they were fairly standardized 3/8 - 18 or so ? I understand that a smaller (223 ) bullet passing through a larger can (308) will allow more gas to escape around the bullet creating more noise.

I have an order in for one of the new AWC Titanium suppressors. They advertise it as multiple calibers, .223, 22-250, 204 Ruger and 22LR.

That sounds like it would be more effective, since they are all pretty close in size.

One of my co-workers uses a 30 caliber suppressor on his AR with a little loss in effectiveness. I've thought about getting a suppressor or paying my NFA tax and making my own for 22LR

Yes, there are suppressors that work for multiple calibers. http://www.advanced-armament.com/product.aspx?pid=865
The AAC 7.62-SDN-6 is a compact fast-attach sound and flash suppressor for 7.62x51mm and 300 AAC BLACKOUT (7.62x35mm) weapons. It is 1.25” shorter than the 762-SD and features a fully welded all-Inconel® baffle stack and front end cap to maximize durability on select fire 7.62mm SBRs. The 762-SDN-6 also functions as a superb multi-caliber suppressor for multiple hosts, providing excellent performance on 7.62 NATO, 300 AAC, 6.8 SPC, 6.5, and 5.56mm NATO. When employed on a 300 AAC BLACKOUT (www.300aacblackout.com), the overall SPL of 126 dB with subsonic ammo is quieter than the 9mm HK MP5-SD.
