Does anyone here know how to make a gun with a model? I just cant seem to get it working!

Does anyone here know how to make a gun? Note that I am not using a tool and that it is a model that is welded to the players hand.

If you do know the please do tell me.

Thanks.

:D

Btw here's what I've done so far with my script

local Player = game.Players.LocalPlayer
local Chara = Player.Character
local Mouse = Player:GetMouse()
local Reloading = false
local FireEvent = script.Parent.FireEvent

function Reload()
		if Reloading == true then
			print("Broke")
			return
		end
		Reloading = true
		print("Reloading")
		local Ammo = script.Parent.Ammo
		local MaxAmmo = script.Parent.MaxAmmo
		local Sound = script.Parent.Handle1.Reload
		if Ammo.Value < MaxAmmo.Value then
			Sound:Play()
			wait(0.6)
			Sound:Stop()
			wait(2)
			Ammo.Value = MaxAmmo.Value
			Sound:Play()
		end
		wait(1)
		Reloading = false
end

function Fire()
	local Aim = Mouse.Hit
	local Ammo = script.Parent.Ammo
	local MaxAmmo = script.Parent.MaxAmmo
	if Ammo.Value == 0 then
		Reload()
		return
	end
	FireEvent:FireServer(Aim)
	print(Aim)
	print("Fire")
	local Sound = script.Parent.Handle1.Fire
	Sound:Play()
end
	
Mouse.KeyDown:connect(function(Key)
	if Key == "r" then
		Reload()
	end
end)

Mouse.Button1Down:connect(function(mou)
	Fire()
end)
