The TEC 9 is a cheap open-bolt handgun manufactured in the United States between 1980 to 1994. It was known for the gun to commonly be converted to fire fully automatic illegally.
In the GTA III Era games, the TEC 9 fires in a very slow rate of fire, holding 50 shots in the magazine. It is commonly used by gangs in Vice City, Los Santos, and Liberty City. When the Hitman skill level is reached, the TEC 9 can be dual-wielded.
