Animation is inconsistent when firing..?

When the joystick value is 0.7 and above, it is constantly firing and animation plays at the same time. (Gun recoil) It's okay.
However, when I fire only once, the animation plays 2 times. (until transition from firing animation to "idle" animation)

In short, I'm trying to make a way of working like in a "shooter" game that fires rapidly when the joystick is pressed, works once when pressed once, and fires one by one when continuously pressed and released. (My attempt is for 2D)

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class pistolAttacking : MonoBehaviour
7. {
8.     public Transform firepoint;
9.     public GameObject bulletPrefab;
10.  
11.     public float bulletForce;
12.  
13.     public Rigidbody2D rbp;
14.     public Joystick AttackJoystick;
15.  
16.     bool isShooting;
17.     public Animator pistolShoot;
18.  
19.     void Start()
20.     {
21.         isShooting = true;
22.     }
23.  
24.  
25.     void Update()
26.     {
27.         if (Mathf.Abs(AttackJoystick.Horizontal) > 0.1f || Mathf.Abs(AttackJoystick.Vertical) > 0.1f)
28.         {
29.             float x = AttackJoystick.Horizontal;
30.             float y = AttackJoystick.Vertical;
31.             float z = Mathf.Atan2(y, x) * Mathf.Rad2Deg;
32.             rbp.transform.eulerAngles = new Vector3(0, 0, z);                
33.         }
34.  
35.     }
36.  
37.  
38.     void FixedUpdate()
39.     {
40.         if (Mathf.Abs(AttackJoystick.Horizontal) > 0.7f || Mathf.Abs(AttackJoystick.Vertical) > 0.7f)
41.         {
42.             pistolShoot.SetBool("pistolShooting", true);
43.             if (isShooting)
44.             {
45.                 StartCoroutine(Shoot());
46.                 isShooting = false;
47.             }
48.         }
49.         else
50.         {
51.             pistolShoot.SetBool("pistolShooting", false);
52.         }
53.     }
54.  
55.     IEnumerator Shoot()
56.     {
57.         GameObject bullet = Instantiate(bulletPrefab, firepoint.position, firepoint.rotation);
58.         Rigidbody2D rbb = bullet.GetComponent<Rigidbody2D>();
59.         rbb.AddForce(firepoint.up * bulletForce, ForceMode2D.Impulse);
60.  
61.         yield return new WaitForSeconds(0.3f);
62.    
63.         isShooting = true;
64.     }
65.  
66. }
67.
