I have a couple of cans, and one of my gunsmith's is going to send me one of the models he's now manufacturing. All I have to pay is for the receiving transfer at my FFL here, and the $200 tax stamp.
My FFL in Idaho is going to add me to his license, and I'm going to become a sales person here for his new suppressors. He has a couple of patents for his design, and it's an all new design compared to other cans on the market. He has taken the last 3 years working on getting it just right. He says it'll be one of the quietest can's available.
Personally I like the idea of putting the can into a trust, but the feds have made that much, much more difficult than buying it as an individual ownership.
Advice, find a dealer that does electronic filing of your paperwork. It'll shave months over the Tax Stamp process.
The hardest thing about telling you what can to buy, is not knowing what caliber/cartridge you'll be shooting. Right now AAC (Advanced Armament Corp.) makes some of the finest 30 caliber cans on the market. Silencer Co is another, and Gemtech is another.
30 caliber cans are large, and quite heavy.
For hog hunting, you might want to get an AR-15 in 300 Blackout. you can buy just the 300 BLK upper and use the lower for either weapon with one exception.
If the lower is registered as a rifle you can't convert it into a pistol by changing the upper into a pistol configuration. And you can't use a registered pistol lower with a rifle upper.
300 BLK ideal for hog hunting, and with a good suppressor you won't need hearing protection. Get your can from a reputable dealer, and put them in your hands before you buy one. That way you'll know the size, weight, and the suppressors decibel cutting specs in advance of your purchase. There is nothing worse than buying a can, spending at least $50 for the transfer, and another $200 for the Tax Stamp, plus $400-1,000 on the can itself, and finding out the can you bought won't serve your needs.
Selling a can is very difficult, because you have to get a transfer authorization from the BATFE before you can even put it in the hands of a FFL dealer, and then getting it transferred to the new buyer. Personal ownership suppressor transfers are much different that doing so in a retail store. Mostly because you need to get a release from the feds just to part with it.
This is a photo of one of my 300 blackout pistols with a can on it. The can is 9" long and weighs as much as the barrel alone.
I separated the can from the barrel for a comparison for the size of the can against the size of the pistol barrel.
