Gun sways way too much

My gun sway script can make my gun sway up too much so you can see that the arms are fake and that the weapon is fake as well. How do I make so that it doesn't do this?

Here's the sway script:

 var amount : float = 0.02;
 var maxAmount : float = 0.03;
 var Smooth : float = 3;
 var SmoothRotation = 2;
 var tiltAngle = 25;
  
 private var def : Vector3;
  
 function Start ()
 {
     def = transform.localPosition;
 }
  
 function Update ()
 {
         var factorX : float = -Input.GetAxis("Mouse X") * amount;
         var factorY : float = -Input.GetAxis("Mouse Y") * amount;
        
         if (factorX > maxAmount)
             factorX = maxAmount;
        
         if (factorX < -maxAmount)
                 factorX = -maxAmount;
  
         if (factorY > maxAmount)
                 factorY = maxAmount;
        
         if (factorY < -maxAmount)
                 factorY = -maxAmount;
                
  
         var Final : Vector3 = new Vector3(def.x+factorX, def.y+factorY, def.z);
         transform.localPosition = Vector3.Lerp(transform.localPosition, Final, Time.deltaTime * Smooth);
        
              
         var tiltAroundZ = Input.GetAxis("Mouse X") * tiltAngle;
         var tiltAroundX = Input.GetAxis("Mouse Y") * tiltAngle;
         var target = Quaternion.Euler (tiltAroundX, 0, tiltAroundZ);
         transform.localRotation = Quaternion.Slerp(transform.localRotation, target,Time.deltaTime * SmoothRotation);    
 }
