Can someone explain how a silencer on a gun works?
361706
It is amazing that anything is able to silence a gun, but gun silencers actually work on a very simple principle. \n\nImagine a balloon. If you pop a balloon with a pin, it will make a loud noise. But if you were to untie the end of the balloon and let the air out slowly, you could pop it making very little noise. That is the basic idea behind a gun silencer. \n\nTo fire a bullet from a gun, gunpowder is ignited behind the bullet. The gunpowder creates a high-pressure pulse of hot gas. The pressure of the gas forces the bullet down the barrel of the gun. When the bullet exits the end of the barrel, it is like uncorking a bottle. The pressure behind the bullet is immense, however -- on the order of 3,000 pounds per square inch (psi) -- so the POP that the gun makes as it is uncorked is extremely loud. \n\nA silencer screws on to the end of the barrel and has a huge volume compared to the barrel (20 or 30 times greater). With the silencer in place, the pressurized gas behind the bullet has a big space to expand into. So the pressure of the hot gas falls significantly. When the bullet finally exits through the hole in the silencer, the pressure being uncorked is much, much lower -- perhaps 60 psi. Therefore, the sound of the gun firing is much softer.

Bound's hubby here:\n\nMany of the answers contained herein are good answers. If you dissect an automobile muffler, there is very little conceptual difference from a firearms' silencer (or more correctly, suppressor). \n\nThe firearm's silencer contains a perforated barrel extension, that allows the propellant gases to flow into the expansion chamber formed by the barrel extension and the outer shell. Between the barrel extension and the outer shell is a medium, typically, steel wool. As the gasses flow into the expansion chamber the gases flow around/through the steel wool, cooling the gasses, and muting the crack of the shot (to a degree). Silencers will work with both sonic and subsonic ammunition ... it is that the silencer is MORE EFFECTIVE with subsonic ammunition. \n\nWhat many people have neglected to state, is the silencer's effect on the external ballistics of the projectile. Typically, the bleed-off of the propellant gasses slows the velocity of the projectile, reducing both its muzzle velocity and its muzzle energy! A firearm shot with both a silencer on and off, will hit in different places, and different effects on the object being shot.\n\nGood luck!

The bolt or the firearm is blown back, by the gases, to feed another round. I believe this is used on the HK G3, and the P7, as well as FAMAS rifle.\n\nIf you aren't refering to firearms, blowback is also a term used to describe the unforseen effects of covert operations.

I believe in CA they ARE considered Illegal. I tried to play at a field years ago with an F2 Illustartor with a silencer and was told that I could not because it's illegal.

GAUGE SNUBBERS\n\nThe irregularity of impulses applied to the fluid power system by some pumps or air compressors causes the gauge pointer to oscillate violently. This makes reading of the gauge not only difficult but often impossible. Pressure oscillations and other sudden pressure changes existing in fluid power systems will also affect the delicate internal mechanism of gauges and cause either damage to or complete destruction of the gauge. A pressure gauge snubber is therefore installed in the line that leads to the pressure gauge.\n\nThe purpose of the snubber is to dampen the oscillations and thus provide a steady reading and protection for the gauge. The basic components of a snubber are the housing, fitting assembly with a fixed orifice diameter, and a pin and plunger assembly (fig. 8-16). The snubbing action is obtained by metering fluid through the snubber. The fitting assembly orifice restricts the amount of fluid that flows to the gauge, thereby snubbing the force of a pressure surge. The pin is pushed and pulled through the orifice of the fitting assembly by the plunger, keeping it clean and at a uniform size.

you load up some hot loads and start shooting. Keep adjusting the elevation and windege till you can put them in the black.\nthen remember the load stats so you can do it again.

They do.\n\n(It bears mentioning at this point that there is such a thing as subsonic ammunition.)\n\nWhen something moves through the sound barrier (accelerates to beyond the speed of sound,) it creates a conical pressure wave that travels some distance behind.  The distance increases between the object and the face of tis pressure wave increases as velocity increases.\n\nThe size of this pressure wave is roughly governed by the size of the object.  Therefore, aircraft make very loud "sonic booms" whereas bullets tend to make a slight popping-whining sound as they travel past you.\n\nThe noise is, believe me, rather unnerving.

Not much.  The pillow *might* help a little bit, but the phone book I would think would serve the purpose of destroying the bullet as much as possible so it could not be matched to the gun's barrel as easy.  \n\nA 2 liter soda bottle will help a little bit.  \n\nNow none of these will even come close to a good quality silencer, but may help a little bit.\n\nCome to think of it, I seem to remember a movie where a guy shot a lady with a gun that had a silencer on it, thought the pillow.  (What was the point? Muzzle flash maybe?)\n\nI think it will effect muzzle flash more than sound.

They are about as loud as a .22 caliber. As long as it's not repetitive, no hearing loss should be a result. The DH and I shoot pistols/rifles every week at the club, but of course hearing protection is involved. I ran track in H.S., but don't even recall being startled by the starter (lol).

I'm not impressed with the .223 round. No recoil, all-plastic can't beat a bad guy with it if you need to. When I'm firing my weapon I disassociate from my emotions, but my Peacemaker does have a little kick, had a Glock .40 kicked worse than my .45 so I sold it. My 1911 I can hit just about anything

Okay... If ur serious then I'm game!!  The piston is attached to the piston rod.  When the rod is pulled down by the crackshaft, kinda like bicycle pedals.. the piston draws air into the cylinder.  Then the crankshaft pushes the rod and piston up causing compression.  Then the spark plug ignites and blasts the piston and rod back down creating power.  Then the crankshaft pushes the rod and piston back up expelling the waste.  The piston is the 'plunger' of the system, kina like the black rubber plunger in a hypodermic needle.

The knob on the side is your elevation, "or Up & Down". The Knob on top is your windage. "Left & right.\nTake 3 very steady shots at a target, not too far away. Look at your target, mark the holes with a pen or cover with tape or something so you do not loose them. Then raise of lower you elevation. Then 3 more shots... then adjust, over & over again. You want to hope that the 3 shats are always together, as you make each adjustment. Once you get the elevation, Next work on you windage. Turning the knob left, moves the shots to the right, & vice versa. You really do not want to have your target too far away in the beginning, because you need to get a tight 3 shot pattern to be able to make adjustments. once you are on target at say 25 or 30 yards, then move the target farther away. In the beginning, you just want that tight 3 shot pattern to make accurate adjustments. Don't forget to hold your breath & squeeze slowly. You will get a stray shot from time to time, but this can be expected. Takes about an hour to do it right.

They make a pellet rifle that takes two of the small CO2 tanks that is very quite and has power of 22 cal rifle.  But if you are rich then a silenced rifle would be sure thing.   They are not illegal like un educated people think.   but they are expensive.  Must buy through a class 3 gun dealer and must wait for FBI background check plus pay $200 tax on the gun.   Best bet is the crossman rifle that takes the CO2 tanks but you must remember that they are power full and deadly. be sure there is nothing behind your target that you wouldn't want to hit with possible misses.

+ It is pretty simple,\nTake out the Magazine (either kind Drum or Stick)\nHold So bullets will face forward and slide them in one by one all facing forward. Just press each one down and it clicks in around the edge. Most are Thompson 45 Cal Semi's. You might find a collector edition single, or a played with auto (but that would only get you into more trouble) \nYou know that now that you have asked, If something bad happens you will be found.\nGood luck (Hope you are a planing on being a re-en-actor or something and only using blanks. If so you will need to alter the muzzle so that the blow back is strong enough to push the bolt back)

I don't have one in front of me but\n1. make sure unloaded (duh)\n2. pull trigger\n3. with right hand grasp the gun in such a way that you can pull the slide back  a quarter to half an inch with only your right hand. wrap your fingers around the back of the slide and have the web of your pointy finger and thumb on the grip under the slide.\n4.squeeze your right hand this will pull the slide back slightly\n5. While the slide is back with your left hand squeaze the little bar in front of the trigger guard and pull it down then pull the slide towards the muzzle.\nVoila' \nNow with slide in hand push the recoil spring forward lift up and pull out. Then the barrel comes out easily. You are done\n\nI recommend  break free clp for cleaning (buy at walmart or anywhere). With spray tube lightly spray the rails on the frame.\nspray the the inside and outside of the barrel spray the inside and outside of the slide. While you are letting this soak use a brush and cotton swabs to clean the mechanism inside of the frame. clean ALL the Clp off and put a drop of clp on the top of the barrel right in front the chamber and put a drop on the top of the barrel 3/4 of an inch back from the muzzle. Then put a drop on each of the rails on the frame. Put back together. \nA couple of things to add: in spite of my explanation it is easy :pull slide back a little, pull down bar, and slide slides forward. If you use jacketed bullets don't worry about getting the bore (inside of barrel) sparkly. An easy way to clean it is with a bore snake. That's right all you need is a bore snake and a can of clp \nDon't clean your gun after every use. Clean it after a thousand rounds or once or twice a year which ever comes first. Let the arguing begin....

It depends on types of pistols and length of barrels. If both barrels are same length then the 9mm will be louder.  The 45 is a sub sonic bullet and 9mm is above 1000 fps.  As far as hearing protection goes you should wear it with both.

With in the casing above the trigger is the fireing mechanism, This consists of 2 springs ( 2 double barrel, 1 for singal barrel) and 2 hammers (1 hammer if singal barrel) The hammers are alined with what we call fireing pins which are also alined with the primer of the cartridge once the gun is loaded.\nOunce the trigget is pulled then the spring forces the hammer to hit the fireingpin, which hits the primer sending a chane reaction through the cartridge for the conbustion to take place with the gunpowder, then the casing(wad) which the shot is positioned behing projects the buckshot up the barrels at roughley 450ft per sec . That is just a simple explanation of a tipical double barrel shotgun. How ever some,  more common in over&unders work on the theory of inertia, where the recoile from the the first shot activates the mechanism for the second shot, its also the same princable for semioutomatic shotguns.
