Hi, This fix should work for almost everyone. If you had the same issue as me it will.
When i Pressed 'ALT + T' twice a wierd gun model popped out of my models chest and the taser didnt appear.
Now you should always try Reinstalling LCPDFR(with admin rights of course), And enable the taser. If you have and it still dosent work, open the console (on US keyboard press the button below ESC, on EU(others i guess?) Press the one besides 'L'. In there Type "Reloadscripts" Without the ". That should work. Hope it helped! If it didnt, Comment below!
