How to Implement First Shot Accuracy?

Question

I am making a fps in unity and i have implemented weapon accuracy by adding random number with the range of my "bulletSpread" to the camera.transform.forward. It works perfectly however I want the first shot from a weapon to be 100% accurate (or close to it). Here is the code for my raycast.

Also for some reason the debug.drawray is not working

 rayDirection = fpsCam.transform.forward;
         rayDirection.x += Random.Range(-bulletSpread, bulletSpread);
         rayDirection.y += Random.Range(-bulletSpread, bulletSpread);
         rayDirection.z += Random.Range(-bulletSpread, bulletSpread);
 
         RaycastHit hit;
         if (Physics.Raycast(fpsCam.transform.position, rayDirection, out hit, range))
         {
             Debug.Log(hit.transform.name);
             Debug.DrawRay(fpsCam.transform.position, rayDirection);
 
             Target target = hit.transform.GetComponent<Target>();
             if (target != null)
             {
                 target.TakeDamage(damage);
             }
 
             GameObject impactGo = Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal));
             Destroy(impactGo, .1f);
         }

 private void Shoot(bool useSpread) {
   // ...
   if(useSpread) {
     rayDirection.x += Random.Range(-bulletSpread, bulletSpread);
     rayDirection.y += Random.Range(-bulletSpread, bulletSpread);
     rayDirection.z += Random.Range(-bulletSpread, bulletSpread);
   }
   // ...
 }
 void Update() {
   // GetMouseButtonDown will only fire on the first frame the mouse is pressed,
   // this would be our first shot
   if(Input.GetMouseButtonDown(0)) {
     // First frame mouse is down, don't use spread.
     Shoot(false);
   } else if(Input.GetMouseButton(0)) {
     // Mouse is held down, use spread.
     Shoot(true);
   }
 }

Thank you for the reply I will try this when I get home my only question is that since not all of my weapons are automatic, won’t those have 100% accuracy on all of their shots?
