How to properly synchronize wepaon switch between players

Options
I am trying to make players switch weapons they have (And show it to other players). I am doing it through activating/deactivating player's children in respective slots of weapon models. But no matter what i do, weapon models don't appear and don't change

Code fore weapon switch:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
using Hashtable = ExitGames.Client.Photon.Hashtable;
using Photon.Realtime;

public class player_weaponequip : MonoBehaviourPunCallbacks
{
[SerializeField] item_mainItem[] items;

public GameObject player;

PhotonView view;

int itemIndex;
int previousitemIndex = -1;



void Awake()
{

view = player.GetComponent<PhotonView>();

}

void Start()
{
if (view.IsMine)
{
equipItem(0);
}

}
void equipItem(int _index)
{
if (view.IsMine)
{

if (_index == previousitemIndex)
return;



itemIndex = _index;

items[itemIndex].itemGameObject.SetActive(true);
if (previousitemIndex != -1)
{

items[previousitemIndex].itemGameObject.SetActive(false);

}

previousitemIndex = itemIndex;

}
}

// Start is called before the first frame update


// Update is called once per frame
void Update()
{
if (view.IsMine)
{
weaponSwitch();

}
}

public void weaponSwitch()
{
if (view.IsMine)
{

for (int i = 0; i < items.Length; i++)
{
if (Input.GetKeyDown((i + 1).ToString()))
{
equipItem(i);
break;
}
// Debug.Log(i);
}

if (Input.GetAxisRaw("Mouse ScrollWheel") < 0f)
{
if (itemIndex >= items.Length - 1)
{

equipItem(0);

}
else
{

equipItem(itemIndex + 1);

}




}
if (Input.GetAxisRaw("Mouse ScrollWheel") > 0f)
{

if (itemIndex <= 0)
{

equipItem(items.Length - 1);

}
else
{

equipItem(itemIndex - 1);

}

}

}

}


public override void OnPlayerPropertiesUpdate(Player targetPlayer, Hashtable changedProps)
{
if (!view.IsMine && targetPlayer == view.Owner) //Подтверждает, что мы синхронизировали оружия
{

equipItem((int)changedProps["itemIndex"]); //Синхронизирует оружия между всеми игроками

}

Debug.Log("Recieved item");

}

}
