Setting Line Render position directly forward from facing of game object

Question

So I have this script here that handles the firing of a weapon using raycasts and I'm trying to have it use a Line Renderer directly forward from the facing of the gun object. Initially I used hitInfo.point as the 2nd point for the line renderer but as there is no collision with the sky the line will not render there. After reading through other answers I determined that transform.TransformDirection(Vector3.forward) should project the line forward but when I run my game the line is always rendered to a fixed point despite which direction my player is facing ( and hence the gun's facing direction). If anyone could point out my mistake here, it would be much appreciated.

     public class RaycastMachineGun : MonoBehaviour {
     
     float mCooldown = -0.1f;
     float mFireRate = 0.1f;
     
     int mGunAmmo = 0;
     int mGunMaxAmmo = 500;
 
     int mGunDamage = 10;
     
     LineRenderer mGun;
     float mGunCountDown = 0.125f;
     float mCurrentCountDown = 0.0f;
     
     void Start () {
         mGun = GetComponent<LineRenderer>();
         mGun.enabled = false;
         mGun.SetVertexCount (2);
         mGun.SetWidth (0.01f, 0.01f);
         mGun.SetColors (Color.yellow, Color.yellow);
         mGunAmmo = mGunMaxAmmo;
     }
     
     void Update () {
         if(Input.GetButton("Fire1") && Time.time > mCooldown && mGunAmmo > 0)
         {
             mGunAmmo--;
             RaycastHit hitInfo;
             Vector3 direction = transform.TransformDirection(Vector3.forward);
 
             if (Physics.Raycast(transform.position, direction, out hitInfo))
             {
                 if(hitInfo.transform.tag != "Player")
                 {
                     Health enemyHealth = hitInfo.transform.GetComponent<Health>();
                     if (enemyHealth!= null)
                     {
                         enemyHealth.mDamage(mGunDamage);
                     }
                 }
                 mGun.enabled = true;
                 mGun.SetPosition(0, transform.position);
                 mGun.SetPosition(1, direction);
             }
             mCooldown = Time.time + mFireRate;
         }
         
         mCurrentCountDown += Time.deltaTime;
         if (mCurrentCountDown >= mGunCountDown)
         {
             mGun.enabled = false;
             mCurrentCountDown = 0.0f;
         }
     }
 
     void OnGUI(){
         GUI.Label (new Rect (5, Screen.height - 45, 100, 100), "Ammo: " + mGunAmmo.ToString () + " / " + mGunMaxAmmo.ToString ());
     }
 }

Also as this is my first question on here, I'm not entirely sure I formatted everything properly, if someone could also point me to where to do that, thanks in advance.

I have since managed to fix my own mistake using the following code

 public class RaycastMachineGun : MonoBehaviour {
     
     float mCooldown = -0.1f;
     float mFireRate = 0.1f;
     
     int mGunAmmo = 0;
     int mGunMaxAmmo = 500;
 
     float mGunDamage = 10.0f;
     
     LineRenderer mGun;
     float mGunCountDown = 0.125f;
     float mCurrentCountDown = 0.0f;
     
     void Start () {
         //Set values for line renderer as feedback
         mGun = GetComponent<LineRenderer>();
         mGun.enabled = false;
         mGun.SetVertexCount (2);
         mGun.SetWidth (0.01f, 0.01f);
         mGun.SetColors (Color.yellow, Color.yellow);
 
         //Intially set the amount of ammo to max
         mGunAmmo = mGunMaxAmmo;
     }
     
     void Update () {
         //Check if player fires
         if(Input.GetButton("Fire1") && Time.time > mCooldown && mGunAmmo > 0)
         {
             //Subtract from ammo
             mGunAmmo--;
 
             RaycastHit hitInfo;
             Vector3 direction = transform.TransformDirection(0,0,1);
 
             //Find the object that is hit
             if (Physics.Raycast(transform.position, direction, out hitInfo))
             {
                 if(hitInfo.transform.tag != "Player")
                 {
                     //Render the line as player feedback
                     mGun.enabled = true;
                     mGun.SetPosition(0, transform.position);
                     mGun.SetPosition(1, hitInfo.point);
 
                     Health enemyHealth = hitInfo.transform.GetComponent<Health>();
                     if (enemyHealth!= null)
                     {
                         //Apply damage to enemies
                         enemyHealth.mDamage(mGunDamage);
 
                         //Create Particles if hit enemy
                     }
                     else
                     {
                         //Create Particles if not hit enemy
                     }
                 }
             }
             else 
             {
                 //Render the line as feedback
                 mGun.enabled = true;
                 mGun.SetPosition(0,transform.position);
                 mGun.SetPosition(1, transform.TransformDirection(Vector3.forward)*1000);
             }
             //Apply firerate cooldown
             mCooldown = Time.time + mFireRate;
         }
         //Turn off line renderer 
         mCurrentCountDown += Time.deltaTime;
         if (mCurrentCountDown >= mGunCountDown)
         {
             mGun.enabled = false;
             mCurrentCountDown = 0.0f;
         }
     }
 }
