Tec9 from cs go to css
Now you see another weapon model, namely the adaptation of te9 from cs go for css.
This is the only tec9 skin that is 90% identical to the original. The differences are only visible in the way you hold the weapon, the animations are also slightly different.
And in general, there are almost no tec9 models for counter strike source. You should definitely try this skin on your client!
For all versions.
