That's mostly what I use, they are indestructible and compact. I have some that are as old as I am and still work perfectly. They can be taken apart to be cleaned as well. Mostly they are polished blue and look nice on blue guns. I posted a bunch of suppressor pics a few days ago under the post "Anyone have experience with Unique pistols?" Take a look. The attached pic is my 77/22 with PH steel can, the second is two BSA rifle projects with barrel profiles to match the suppressor, you can see where barrel ends and can begins. They're not the quietest but they are the prettiest and toughest. Not sure about US law to get them but they are the most common in England and have been around since WW2.
