Ok Nvm It solved, to fix it just go to hl2mp_player.cpp > CHL2MP::FireBullets and do this
void CHL2MP_Player::FireBullets ( const FireBulletsInfo_t &info )
{
/*
// Move other players back to history positions based on local player's lag
lagcompensation->StartLagCompensation( this, this->GetCurrentCommand() );
*/

FireBulletsInfo_t modinfo = info;

CWeaponHL2MPBase *pWeapon = dynamic_cast<CWeaponHL2MPBase *>( GetActiveWeapon() );

if ( pWeapon )
{
modinfo.m_iPlayerDamage = modinfo.m_flDamage = pWeapon->GetHL2MPWpnData().m_iPlayerDamage;
}

NoteWeaponFired();

BaseClass::FireBullets( modinfo );

/*
// Move other players back to history positions based on local player's lag
lagcompensation->FinishLagCompensation( this );
*/

}
