Suppressors are a fairly significant deal in the USA, by which I mean it is not something you can buy over the counter at a gun store and leave with the same day. It takes paperwork and around 6-7 months of waiting for the papers to be processed, in order to obtain a suppressor.
Here in New Zealand they are legal and have no restriction... have you heard a car with a hole in its muffler?
Makes shooting much more comfortable for both the shooters and those nearby.
Of course for tubes of plastic or metal they can be quite expensive... as I mentioned getting a suppressor for my SLR (FN FAL/L1A1) would be $750.
you mean silencer not suppressor
Supppressors and silencers are terms that mean essentially the same thing and are often used interchangeably.
Of course in the strictest sense a silencer cannot be used with supersonic ammo and often is built in to a weapon and includes holes drilled into the barrel so that normally supersonic ammo becomes subsonic.
A good example is the suppressed model of the Makarov pistol which has a detachable silencer and a drilled barrel so that it is quiet even with standard (supersonic) ammo.
Only in Hollywood are they called silencers, the correcy industry term is SUPPRESSOR. Nothing is totally quiet, we are talking about a dB reduction from 160 to 130, still loud but not loud enough to cause instant hearing damage.
Actually when firing my .22lr rimfire bolt action rifles with suppressors fitted you hear a faint click of the rim being crushed and the other sound you can hear is the impact of the bullet on the target. There is no Phutt sound or blowing sound like you hear in movies... that is of course with subsonic ammo.
a silencers and suppressorare are 2 things, one cancels as much noise as possible and indeed is hard get, the other one is is build diffrently and mostly suppresses the flash and only some noise
Then the difference is the ammo and action of the weapon used.
Here in NZ as I said there are no limitations... if you want you can phone a gunsmith and have them build you a rifle... the de lisle is a popular design to copy... 45 calibre round... any one you want, including 45/70, with an old worn out 303 bolt action rifle... wont be cheap but will be quiet and effective.
We have fairly strict laws regarding pistols however so suppressed handguns are more exotic.
A silencer is a media/movie term, although it doesn't help that the ATF/government also tends to use that term on some forms.
It doesn't matter what you call them here they pretty much mean the same thing and are interchangeable.
Generally speaking though if you ask for a silencer it will be for a bolt action and they will be expecting you to use subsonic ammo and the weapon will actually be quiet.
A suppressor is more for semi automatics and with supersonic ammo so you can shoot without ear protection.
I have taken a .22 out to shoot rabbits with a silencer fitted only to find it was zeroed for high velocity ammo after my first shot which went about half a metre high. The rabbit heard the impact behind it on the slope it was standing in but because I was lying down it didn't know what was happening so it ran about 3 metres and then stopped standing up on its back legs listening to work out what had happened. I gave the top turret a turn 8 clicks down and took another shot that hit the dirt about half a metre low, to which the rabbit jumped up in the air about a metre and turned and ran back the 3 metres to where it was when I first saw it and stopped and listened on its toes. I cranked the top turret up 4 clicks and shot it through the eye... it flopped over dead.
Once it was shooting to aim I had no further problems and just used a hold over for longer range shots.
