No change to the Tec-9’s numbers in Valve’s file since May 2024.

CS2 weapon · Pistol · T side Tec-9

Valve: “Highly mobile, effective at range and up close.” An ideal pistol for the Terrorist on the move, the Tec-9 is lethal in close quarters and features a high magazine capacity.

Buy Tec-9 when…

You can take the first headshot inside 9 m — one helmeted headshot kills there.

Spray & firing mode

Phase
10 bullets · 1.08 s of fire at 500 RPM · 8 left in the magazine.
Valve’s recoil inputs: kick 23 ± 3 · direction variance 60.Valve’s file holds these inputs, not the path the bullets take — so no path is drawn here.

Firing mode guidance

Semi-automatic — one shot per click. Pace the taps: each shot widens the next.

Spread still varies shot to shot — a guide, not a guarantee.

What beats the Tec-9?

Weapon · edge30 m · headCost
Hits to kill from Valve’s file at your distance and armour — not win rates. Shotguns left out: pellets decide.

Economy context

  • Tec-9 + Kevlar + helmet$1,500$2,600 left
  • Tec-9 + Kevlar$1,150$2,950 left
  • Tec-9 alone$500$3,600 left
  • Glock-18 + Kevlar + helmet$1,200$2,900 left
Kill reward $300 — 2 kills pay the gun back. Armour: Kevlar $650, with helmet $1,000 (Valve’s items_game.txt).

Counterplay tips

  • Fight it beyond 22.09 m: past its standing accurate range even the first shot is not sure to land.
  • Catch it moving: on the move its first shot is only sure within 26.23 m.
  • It needs 5 chest hits at 15 m against armour — trade it rather than duel alone.
  • It moves at 240 u/s — expect it to reposition quickly.
  • Drop its holder first: they lose a $500 gun, and each kill it makes pays them $300.

No — 2 hits to a helmeted head at 30 m (68 each).
