Problem with people holding weapons

[Freezak]

Hello, well i have tried everything but didn't figure it out. Simply every person i see (even me) have their weapon [instead in hand(s)] in stomach. This is really annoying as i see people shooting from their fingers. I don't know what to do, i tried remounting all the games, didn't try reinstalling the whole garry's mod or other game though, it takes some time and i believe there is easier fix for that. If anyone know what to do, please post here. Thanks in advance.
