Bullet pickups/Accessing the inactive objects

How to pick up bullets more efficiently? I have a bullet pickup script with a string and object with shooting script. Everything occurs in shooting script: shooting raycasts, bullet count(each weapon has it's own magazine size and bullet count). But I can't increase it from the bullet pickup script because each time I change weapon, every other weapon is disabled. E.g the pickup is meant meant for a pistol but I enabled rifle for now. I go to pickup loop through the weapons(I CANT LOOP THROUGH INACTIVE OBJECTS AND IT GIVES ME ERROR) How can I iterate through inactive objects? Or how else to manage bullets?

  public class BulletPickup : MonoBehaviour
     {
         public int bulletAmount = 10;
         public string weaponForPickup;
         GameObject weaponRoot;
         private void Start()
         {
             weaponRoot = GameObject.FindGameObjectWithTag("WeaponRoot");
         }
         private void OnTriggerEnter(Collider other)
         {
             if (other.tag == "Player")
             {
                 foreach (Transform weapon in weaponRoot.transform)
                 {
                     if (weapon.gameObject.GetComponent<ShootingScritpt>().GetWeaponType() == weaponForPickup)
                     {
                         weapon.gameObject.GetComponent<ShootingScritpt>().AddFoundBullets(bulletAmount);
                     }
                 }
                 Destroy(gameObject);
             }
         }
 
     }
