The Hush puppy was a special Smith&Wesson 9mm automatic read about it in book by a Vietnam era SEAL he said that the suppressor(true term for a silencer) absorbed so much gas that that the slide was unable to action on its own so you had to pull the slide back manually after each round which limited the use of the gun for dogs they also used them when they did grab missions to kill any guards around the targets hooch.One SEAL with a Hush Puppy for each guard.They also made a suppressor for the M-16 but the SEALs never used them in combat because they had to cocked each round thanks to gas absorption and the lowered powder in the special rounds.

Modern suppressors are much better and wont limit the guns action and the trend today is more for sound reduction rather than total silence(which is a rather Hollywood notion anyway but a very good suppressor can make a gun not sound like a gun quite well) many sniper rifles attach a suppressor but still fire full power rounds which makes the rifle much quieter than without the suppressor and adds the benefit of almost no muzzle flash a side benefit of the suppressor absorbing gasses of course by using full power ammo the rounds will still be heard if they pass near by someone braking the sound barrier.

The SEALs probably used M-4s with suppressors(with full power ammo they will sound like a .22 pistol which with the ambient noise in a city would make them gather little attention) and or MP5SDs which have a built in suppressor and are pretty quite but fire 9mm.The M-4s would have only been heard for a block or so at most rather than throughout the whole town.

There is one revolver that can use a suppressor the Russian Nagant revolver but its ammo the shell casing went past the bullet and into the chamber giving it a seal and allowing a silencer to work any other revolver it would not work well.These special Nagants where sometimes used by Soviet Elite troops during WWII.
