I have mostly 9mm and 45's.  I understand that 45's are "easier" to suppress, but 9mm is MUCH cheaper (plus I have about 10k rounds in the safe room).

With the 9mm cans, can you shoot without hearing protection?  

I also want to be able to mount it on a 9mm AR, can a pistol can be mounted on a rifle?

How well does a .40 can suppress 9mm?  Again with an emphasis on shooting without hearing protection.

Can you travel to a different state (where they are legal, obviously) without paperwork to the ATF?

Anything you want to add, be my guest.

It will be purchased on my Trust along with my SBR, so I am covered there

If talking handguns you got it backwards da 9mm silences the best.  You want to be looking at the SWR Trident or AAC Evolution 9 with the multiple mounts to go pistol and rifle.  Gemtech has a new product out but no reports yet on the web how it works.

A 9mm suppresses MUCH better than a .45 can when shooting dry.  Most .45 cans require some wet medium in the can to gain adequate sound suppresion.  Shoot subsonic ammo through the 9mm for best suppression.  

Yes, you can shoot a quality 9mm can without hearing protection.  Subsonic ammo is key or you get the supersonic crack.

Mounting a .40 can on a 9mm pistol is a challenge because of thread/barrel sizes.  You would need some type of adapter to go between the pistol and the can.

You can travel to anywhere silencers are legal without filling out the ATF travel form.  You can pass through states where cans are not legal as long as your destination allows silencers.  I would always keep a copy of my Form 4 with the NFA item and would gladly show it and explain the NFA world to any LE that asks.  The Form 4 is technically a tax document and you are not required to show it.  I personally feel that people who say, "I would never show my personal information to LE; it is none of their business..." are foolish.  You will beat the rap but you will take the ride.  Help educate LE in a polite, professional way.  Since you are doing a Trust transfer I'd also keep a copy of the Trust with me.

You will need to fill out an ATF travel form to transport the SBR.

Some pistol cans can be mounted on rifles.  Buy a can that has a booster for use on (most) pistols and a fixed barrel adapter for use on ficed barrel weapons, like an AR.

Best of luck,

Isn't almost ALL .45 subsonic?  Thats why I thought it would be easier to suppress...

Its a bit harder to suppress because of the nearly half inch bore (or so I've been told)

ETA: I've had my 9mm suppressor for about a week and am pretty impressed with its performance.

45 silencer real nice if you want a 2"X12" submachinegun sized silencer, if you want something compact on a handgun it just has too big a hole through the middle to trap the sound.

You must understand that .45 cans should be shot wet.  A good .45 wet will be quieter than a good 9mm dry.  Try something like an AAC Evo-45, SWR HEMS II or a KAC can.  These all have wonderful booster systems that allow reliable cycling and with proper use of an ablative are very quiet.  

Go to your local pharmacy and buy syringe bodies (needles not needed).  Then hit the pet store for some aquarium tubing.  Last stop is Home Depot dor a large $6 bottle of wire pulling gel.  Cut the tubing to fit the syringe and have enough tubing to get the gel into the blast baffle area of the can.  This makes for easy "topping off" of the wet medium.
