How to do Switching Weapon System

Well i’m making an FPS and blah blah…I need more than 1 gun, so, what’s the easiest way to do a weapon switching system (C# or JavaScript)? I have my Player Like this:
Player > Main Camera > PrimaryWep > M4; Bullet-FirePoint;
And my Gun script(Attatched to PrimaryWep, M4 is just the 3D model) works like this:

#pragma strict
//Weapon Script

var bullet : GameObject;
var gunBarrel : Transform;
var reloadSound : AudioClip;
var shootSound : AudioClip;
var emptySound : AudioClip;
var hudAmmo : GUIText;
var hudMags : GUIText;

var ammo : int;
static var mags : int;
var fireRate : boolean;
var shootTime : float;

var aimingDownSights : boolean = false;

function Start () {

	ammo = 45;
	mags = 225;
	fireRate = true;
	shootTime = 0;

}

function Update () {

	hudAmmo.text = "Loaded:" +ammo;
	hudMags.text = "Stored:" +mags;

	if(Input.GetButton("Fire1")){
		if(ammo > 0){
			if(shootTime > 0.1) {
				ammo--;
				audio.clip = shootSound;
				audio.Play();
				Instantiate(bullet,gunBarrel.position,gunBarrel.rotation);
				shootTime = 0;
				if(aimingDownSights){
					animation.Play("ADSAnim3");
					} else {
					animation.Play("FireAnim1");
				}
			}
		}
	}
		
	if(ammo == 0 && !audio.isPlaying){
		audio.clip = emptySound;
		audio.Play();	
		
	}
		
	shootTime += Time.deltaTime;
	
	if(Input.GetKeyDown(KeyCode.R)){
		if(ammo == 0 && mags > 0) {
			audio.clip = reloadSound;
			audio.Play();
			animation.Play("ReloadAnim");
			ammo = ammo + 45;
			mags = mags -45;
		}
	}

	if(Input.GetButtonDown("Fire2")){
		aimingDownSights = true;
		animation.Play("ADSAnim1");
	
	}
	
	if(Input.GetButtonUp("Fire2")){
		aimingDownSights = false;
		animation.Play("ADSAnim2");
	}	
}

Well i’m thinking about crating another script like this, but changing the ammo and etc…Also i’ll make another Bullet-FirePoint(Position where the bullet is instantiated) and etc…

So what’s the easiest way to do this? I was thinking about something like: Inside Main Camera I’ll create another empty called SecondaryWep, then i’ll attatch the Gun2 script, and put inside another gun model, and the other Bullet-FirePoint…then use “activeSelf” to enable and/or disable the guns when i press 1 or 2…Can someone help me with this script? Also if you know a better way to do this please tell me (and please write the script, if you can)…

Programming is programming so either language is fine. C# is generally faster than JS but JS is still fine. I see you use java yourself, which I’m not familiar with but here’s a java tutorial on YouTube.
