The Tec-9 was designed by George Kellegren and manufactured by Intratec, originating from Sweden and the U.S. Its production lasted from 1985 to 1994 in which it was originally banned in the U.S. by the Federal Assault Weapons Ban. Its open-bolt predecessor the Interdynamic KG-9 was famously known as being easily converted to fully automatic fire, which led to the development of the closed-bolt and semi-automatic only KG-99 and its various offspring including the TEC-9.
In-game, the Tec-9 holds 32 rounds of 9mm pistol cartridge. It starts with 120 rounds in reserve and 32 in the initial magazine. It costs $500 and kill award is default.
Unless you're a highly skilled pistol user, avoid close-ranged combat with all users whenever possible.
Once a Tec-9 user sprays bullets and you are not in close range, he is less likely to score a lethal headshot. This will also give you more time to eliminate an enemy wielder.
More accurate and powerful weapons are recommended to engage users.
Watch out for enemies who are wielding the Tec-9 if you have to reload. The Tec-9 has a large magazine and can be reloaded quickly, giving them an advantage if you are equipped with weapons that have a low rate of fire. small magazine capacity, and lengthy reload time.
Rushing at enemies armed with this weapon is ill-advised, unless they are not aware of you.
Weapons with a high rate of fire can counter Tec-9 users at close ranges.
Unlike depictions of some movies and video games, the Tec-9 cannot fire full auto without modification. In Counter-Strike: Global Offensive, the Tec-9 fires semi-auto, just like the original civilian version of the Intratec Tec-9.
