Give a random player a weapon?

I have a script that chooses a random player, but I don't understand how to give that random player a weapon. Any help would be appreciated :D

wait(10)
dft = {} 
local plrs = #game:GetService('Players'):GetChildren()

function GetPlayers()
    local c = game.Players:GetChildren() 
    for i = 1, #c do 
        table.insert(dft, c[i].Name) 
    end 
end

if plrs >= 2 then
function Randomize()
    GetPlayers()
    local d = math.random(1, #dft) 
    local s = d 
    local m = Instance.new("Message", game.Workspace) 
    m.Text = "The random player is ... "..dft[s].."!" 
    wait(2) 
    m:Remove()
    local rndm = game.Players:FindFirstChild(dft[s])
    if (rndm ~= nil) then 
        local Player = rndm.Character
        Player:MoveTo(Vector3.new(6, 13, 49))
    end
end

while wait(20) do    
    print("Done waiting.")
        print("Randomizing.")
        Randomize()
break
    end


else
    local h = Instance.new("Message")
h.Parent = workspace 
h.Text = "Not enough players."
wait(10)
h:Remove()
end
    plrs = #game:GetService('Players'):GetChildren()
