Cant switch between legacy animations

I have 2 animations for an FPS arm/gun. One for hipfire and one for aiming down sights. The problem is it only plays the hipfire animation even when aiming down sights. I'm using a simple javascript in Unity 5.2 Is there something I'm missing?

The "Pistol001Shot" is the hipfire and the "Pistol001ShotAim" is the aim down sights.

  var gunsound : AudioSource = GetComponent.<AudioSource>();
  
  function Update () 
  {
      if (Input.GetButtonDown("Fire1"))
      {
          if (Input.GetButtonDown("Fire2"))
          {
              gunsound.Play();
              GetComponent.<Animation>().Play("Pistol001ShotAim");
          }
          else if (!Input.GetButtonDown("Fire2"))
          {
              gunsound.Play();
              GetComponent.<Animation>().Play("Pistol001Shot");
          }
      }
  }
