How do I make a projectile bullet?

Hello,

I'm trying to make a weapon and this is its LocalScript:

local Players = game:GetService("Players")
local Player = Players.LocalPlayer
local Mouse = Player:GetMouse()
if not Player.Character then repeat wait() until Player.Character end
local Character = Player.Character
local Humanoid = Character:WaitForChild("Humanoid")

local Glock = script.Parent
local Handle = Glock:WaitForChild("Handle")
local Muzzle = Glock:WaitForChild("Muzzle")

local OnActivated = function()
    local Bullet = Instance.new("Part", workspace)
    Bullet.Material = Enum.Material.Neon
    Bullet.CanCollide = false
    Bullet.Anchored = false
    Bullet.Locked = true
    Bullet.FormFactor = Enum.FormFactor.Custom
    Bullet.BrickColor = BrickColor.new("Bright yellow")
    Bullet.Size = Vector3.new(0.25, 0.25, 5)
    Bullet.Position = Handle.Position
    Bullet.CFrame = CFrame.new(Bullet.CFrame.p, Mouse.Hit.p)
    local BodyVelocity = Instance.new("BodyVelocity", Bullet)
    BodyVelocity.Velocity = Bullet.CFrame.lookVector * 120
end

Glock.Activated:Connect(OnActivated)

But I realised the bullet's velocity is really slow. When I tried to increase it, the bullet goes in a weird way.

Is there a way I can use it without making it look weird? Thanks.
