Suppressor

The suppressor (or silencer as it's also known as) is an attachment put onto guns in frount of the muzzle to suppress or silence (hence the name) the shots fired. It is mainly used for stealth so you can fire your gun without anyone hearing you. It is seen in only a few GTA games and only really has a use in one but it's still worth mentioning.

In Grand Theft Auto 2 the first silenced gun the Silenced Machine Gun was used so as not to attract attenction from pedestrians police and gang members but appart from that it is not used in any stealth missions and therefore serves no real purpose appart from some silenced fun.

In Grand Theft Auto: San Andreas the Silenced pistol was introduced. Unlike in GTA 2 where the Silenced Machine Gun had no real purpose the silenced pistol serves a purpose now. It can be used in many missions where it is nessecary to use stealth and where it isn't nessecary.

In Grand Theft Auto: The Ballad of Gay Tony the Assault SMG has a silencer but serves no purpose. A weird thing about the Assault SMG is although the suppressor does quiet the firing sound (like what it's suppose to do) when you do fire it it will alert pedestrians and police around you even though there is a suppressor on it.
