Goddamnit dimka, I already gave you the necessary information. As a server owner you should be eager to put as much effort as possible into it rather than awaiting someone to do it for you.
There's nothing difficult in changing the **** @RefWeaponID to your desired ID, then equipping it through _FN_ADD_INITIAL_EQUIP, assigning the returned ID64 to a variable, then using the ID64 to update the item at _Items.. I'm getting sick and tired of it..
When you're looking at _AddNewChar for days, ..ADD..EQUIP.. was apparently not obvious enough..
Sorry
