Also called a silencer, these are legal in the US, but regulated by the same agency that handles machineguns. PART of the noise created by a gunshot is the shockwave created by the expanding gasses from the burning gunpowder. A suppressor captures most of the gasses in a system of baffles or chambers, slows and cools them, and releases them gradually. They do not truly silence a gunshot, but they can reduce or suppress much of the sound and muzzle flash.
The Maxim suppressor was made of steel.
Suppressor
Sometimes it will.
Yes, in general a suppressor can increase rate of fire by 50-100 rounds/ minute.
While not designed to make a gun louder, a muzzle brake usually has that effect.
You have to make one
If you have the time and money, you'd need to make a suppressor from scratch, since the average Thompson was not able to fit a suppressor.
By allowing the gases to expand in a controlled fashion.
YES! Any firearm that doesn't use a suppressor (silencer) will have a loud sound.
Usually suppressors can be screwed on, so there should be notches to screw it on.
Depends on the suppressor. Many are made to be taken apart, soaked in solvent, brushed, and reassembled.
No there is nothing like that.There is a pistol and a automatic hand gun Glock.
