change weapon only one player in network

Hello, my problem is I want to make my player to change weapon in my fps but when the player changes weapon also change them to more, if I use networkView.isMine those of most players can not see the gun, as I do to change weapon and only change my character while those of most can see it?

I show the script for weapons:

var m9 : GameObject; var ak :GameObject; var fire : GameObject;

function Update () {

   //   if (networkView.isMine){
      if (verif == 1) {
     ak.SetActive (false);
     m9.SetActive (true);
 }
 if (verif == 2) {
     ak.SetActive (true);
     m9.SetActive (false);
 }
 }

function OnTriggerEnter (other : Collider){ if (networkView.isMine){ if (other.CompareTag ("M9")) {

     m9.SetActive (true);
         fire.GetComponent(Shoot).enabled = true;
         verif = 1;
  
 }
     if (other.CompareTag ("ak47")) {
         ak.SetActive (true);
         fire.GetComponent(Shoot).enabled = true;
         verif = 2;


  
 }

} }

are written in another script keys to switch weapons with a simple switch

sorry for my English, I'm using google translate

a greeting
