FM_CmdStart
This plugin will perform better if you work with Ham_Weapon_SecondaryAttack and m_flNextSecondaryAttack instead. Since there's no secondary attack in Deagle, you could just call it manually on Ham_Item_PostFrame as CS itself does.

Also, you should reset the model on Deagle holster and block this function if player is using shield.
