How to get a tool and remove a tool when using KeyDown?

What I am trying to do is when you press 'q' then it gives you a gun but what I am wanting is if you press it again, it gets removed. I am not sure on how to do this. An explanation would be very helpful.

01local Player = game.Players.LocalPlayer
02local Mouse = Player:GetMouse()
03local Tool = game.ReplicatedStorage['Pistol']
04 
05Mouse.KeyDown:connect(function(Key)
06    local NewKey = Key:lower()
07 
08    if NewKey == 'q' then
09        Tool:Clone().Parent = Player.Backpack
10    end
11end)

I highly suggest using the UserInputService and looking at input began/ended. Mouse.KeyDown is outdated. jtefurd 50 — 8y

You would and should use arguments for this o.o

There are different ways you can go about doing this but I am going to use classical ole if statements cause I love those, they're nice :D

Anyways...

01local Player = game.Players.LocalPlayer
02local Mouse = Player:GetMouse()
03local Tool = game.ReplicatedStorage['Pistol']
04 
05Mouse.KeyDown:connect(function(Key)
06    local NewKey = Key:lower()
07 
08    if NewKey == 'q' then
09    if Player.Backpack:FindFirstChild('Pistol') == nil then --If the pistol is NOT in the backpack
10        Tool:Clone().Parent = Player.Backpack --Puts the pistol in the players backpack
11    elseif Player.Backpack:FindFirstChild('Pistol') ~= nil then --If the Pistol IS in the backpack
12    Player.Backpack.Pistol:Destroy() --Destroys the pistol (removes it) c:
13    end
14end -- almost forgot we needed to add an extra end (i think) to close off our extra if statement
15end)

Explanation: The first if statement basically says if the Pistol is equal to nil (doesn't exist) then it'll put the tool (Pistol) in the players backpack. If the tool is not equal to nil('~=', is there) then it will destroy the Pistol.

Extra Info: You should always use :Destroy() when removing / deleting something with a script so that way it doesn't cause "zombies" in your code and hog up memory, which could cause lag if you use rusty old :remove() in too many scripts.

This is one of the many ways you can do this but I think this is the quickest way.

I hope this works, if not let me know!
