1. Yes you can buy a suppressor,
2. Yes you can own one,
3. Yes you can even make your own,
. . . but . . .
1. You have to buy it from a Class III ATF licensed FFL dealer.
2. You have to pay a $200 tax per each suppressor & every time it is sold the $200 has to be paid buy the buyer.
3. If you make your own you will need to have your FFL, pay the $200 tax and fill the RIGHT form out correctly.
A suppressor will cool & slow down the expanding gasses once they exit the muzzle severely limiting the sound from the muzzle blast but a bullet going faster than the speed of sound (900 fps or faster IIRC ) will still break the sound barrier thus the "crack" will be heard. That's why .45ACP, Subsonic 9mm & .22lr make for good suppressed pistols.
Wouldn't it be nice if suppressors were legal for hunting, sport shooting & plinking?
It is not illegal in GA to own a suppressor and you don't have to have a "special class license". You just have to submit the paperwork to the ATF and pay a $200 Tax for each suppressor that you buy. Here are a few of my (illegal according to edge) suppressors.
Suppressed Ruger 77/44
I strongly concur... With the right round & supressor, they are QUIETER than Hollywood quiet... Downright, SCARY quiet!!! You can hear the trigger/firing pin snap & then the bullet hit the target 100 yards away. This was with a fancy, German .308.... It was amazing!!!
Nice cans Climber. I just ordered a Marvel .22 conversion slide(with threaded barrel) for my Norinco 1911 frame and an AAC Aviator silencer from Polite Society. Mark from P.S. is very helpful if you have any questions and their web site can answer alot of questions. One interesting note, at least as far as .22 silencers go - adding a silencer typically will cut your group size in half. I guess it sort of works like an inverse BOSS system. http://www.politesocietyinc.com/
