how quite is a suppressor really?

    I am considering buying a suppressor. I have a 1911, and M and P in 9mm. I have seen the decibel ratings, and realize that they are not movies quite, but are they seriously worth it? can you shoot without plugs? If I shot at a groundhog with a suppressed rifle would it know it if I missed by just the sound? Not that I plan on missing. Anyway, any knowledge would be appreciated.

    Worth it is a relative term. And I doubt anyone will speculate on what a groundhog is thinking.

    I say go for it... it makes a big difference. And I think everyone who can own one should.

    Ok, let me add another question then, what suppressor, for what pistol of the two listed.

    How quiet they are depends on the suppressor itself, some are very quiet, some just take the edge off. Generally speaking the smaller the can the louder it will be. I have very small GemTech for a 9mm that reduces very little, really a waste to tell the truth even with subsonic ammo. I have a Ceiner can for my .308 that allow shooting indoors without earplugs very easily when subsonic is used, and outdoors with any ammo. The can on my 300 Whisper is the same way.

    When I decided to build up a 10/22 for a suppressor I decided on an integral simply because they use more baffling and more cubic inches of expansion space and are quieter than most screw on cans.

    They are quite fun!

    Some are more quiet than others though.

    All of my pistol caliber suppressors can be comfortably shot without hearing protection -- especially after adding a little water.

    To the question on handguns, yes, with most good quality cans you can shoot without ear plugs, especially outdoors, though sometimes I've found that indoors you might want to stick to sub-sonic ammo.

    If you're shooting ammo that moves faster than 1,126 fps (of so, depending on elevation), the sonic crack of the bullet is going to be louder than the report from the suppressed gun. So a bullet passing an animal at supersonic speeds is going to make a noise that they absolutely will hear. (Though, it won't appear to come from your direction.) If you can get or load subsonic ammo, you'll be better off.

    A good can will -- in general terms -- reduce the very distinctive and loud blast of a gun shot to more like the noise of a door banging shut. How big a door and how hard it's slammed is going to depend on the size and design of the can and how much gas is being dissipated.

    A subsonic .22 can often be suppressed so it sounds about like an air rifle -- sometimes even a pretty quiet air rifle. Semi-autos tend to be less effectively suppressed as there is gas escaping from more places. Rifles (especially full-speed cartridges) tend to suppress just to the point of not being painful to shoot without ear pro.

    I have a suppressed 22lr (Tac-65) and .223 (Gemtech). The host weapon is a TC Contender (g2). The 22lr is extremely quiet and a real pleasure to shoot. The .223 makes shooting m855 .223 ammo out of a 11.5" barrel bearable. With the .223 I can shoot without hearing protection. However, I usually still use hearing protection because it is still loud.

    My only experience with a suppressor was with a factory one on a MAC 11, that I bought when I was a Class III dealer. Naturally I test-fired it, but I wasn't impressed. It reduced the sound of the .380 to about that of a .22 (or so it seemed from my vantage point as the firer). Big deal. For this kind of performance, I wouldn't go through the hassle of a tax stamp. It did look cool on the gun, though.

    Strange. I thought the Sionics can was supposed to be good, at least for its day. Was it the wipes kind or the later wipeless version? (Wipes could have been toast which would degrade performance.)

    The biggest benefit for most users probably was giving you a safe place for your support hand. :)

    It was the single-stage type with wipes, I suppose, although I never took it apart to find out. I bought it new from SWD circa 1981, so wear wasn't an issue. I put maybe 50 rounds through it total before I sold it to someone else.

    Yes, exactly. The gun just didn't look right without the suppressor. It came with a short strap to hold down the muzzle if you didn't have the suppressor mounted. The suppressor had a black foam-rubber sleeve and then a Nomex cover over that so that your hand would be protected from the considerable heat that would quickly build up. (These are all my somewhat hazy recollections.)

    A good centerfire rifle suppressor will reduce the report to something akin to an air hose disconnecting, a .22lr, or 132-138 dB, take your pick which one makes more sense.
  12. Go to youtube and watch some suppressor videos. You should be able to get a good cross section of suppressors and results from them.

    Better yet, haul your laptop out into a field and play one of those videos for a groundhog and watch to see if he notices the sound of the shot. I mean, really, that's the only way to be sure.

    I'm glad to see there is at least a sense of humor here :).
  15. Well, it all depends on if the groundhog you are shooting at is deaf or hearing impaired. :D Some hogs seem to just sit there and ignore the shot until they get a fix on the location of the shooter. I can tell you with certainty, a suppressed rifle (or handgun) will allow you to shoot at the groundhog longer, or for more shots, than a nonsuppressed gun.

    My Osprey on an FNP 45 shooting Wolf FMJ is definitely quiet enough to use outdoors without hearing protection. The sound of the bullets hitting the steel plates at 10 yards is way louder than the report. In fact a .22LR with ear muffs is perceptually louder.

    I've not stood along side anyone else shooing it yet -- right behind is the "quietest" location because you are in the acoustic "shadow" of the gun. The decibel tests are typically done 3' to the side, even with the muzzle which has got to be close to the worst case scenario other than getting hit with the bullet :)

    I watched the posted Osprey video with the sub caliber conversions. Anybody know if this can be used with a .308? How loud/effective is it?

    Check out Liberty Suppressors, they make some great stuff.

    .223 suppressed sounds about like .22 magnum unsupressed

    Plenty of gas back in the face too if you shoot it from an AR15.


    ...and the "Gasbuster" charging handle does virtually noting to mitigate.
