Raycasting Not Working Right

Help and Feedback Scripting Support
#1

I want to make a gun system.

The raycasting is weird, you have to aim infront of someone to make a hit.
I don’t know how I can make it faster, someone help that might

I really need help and it would be appreciated

Local script

function OnActivated(ActivatedToolYesOk)
	local Player = game.Players.LocalPlayer
	local PlayerMouse = Player:GetMouse()
	local FireTool = script.Parent
	local PlayeMousIcon = Player:GetMouse()
	if Ammo >= 1 then
		if CurrentReloading == false then
			wait()
			Ammo = Ammo - 1
			bullet = CreateBullet(PlayerMouse.Hit.Position)
			local shakeRate = 0 --how often to shake the screen in seconds. 0 is default, around 0.0166 seconds.
			local shakeMin = 0 --the minimum amount of shake to apply, use whole numbers only
			local shakeMax = 400 --the maximum amount of shake to apply, use whole numbers only
			Player.Character.Humanoid.CameraOffset = Vector3.new(math.random(shakeMin, shakeMax)/1000, math.random(shakeMin, shakeMax)/1000, math.random(shakeMin, shakeMax)/1000)
			wait()
			Player.Character.Humanoid.CameraOffset = Vector3.new(0,0,0)
			script.Parent.PistolEvent:FireServer(PlayerMouse.Hit.Position, FireTool)
			
			local raycastParams = RaycastParams.new()
			raycastParams.FilterDescendantsInstances = {Player.Character}
			raycastParams.FilterType = Enum.RaycastFilterType.Blacklist

			local raycastResult = workspace:Raycast(script.Parent.Handle.Position, (PlayerMouse.Hit.Position - script.Parent.Handle.Position)*300,raycastParams)

			if raycastResult then
				local hitpart = raycastResult.Instance
				local Model = hitpart:FindFirstAncestorOfClass("Model")
				if Model then
					if Model:FindFirstChild("Humanoid") then
						if Model:FindFirstChild("Humanoid").HealthChanged then
							PlayeMousIcon.Icon = "rbxassetid://7193947094"
						end
					end
				end
				wait()
				PlayeMousIcon.Icon = "rbxassetid://62814275"
