fusion firearms has some nice low profile adjustable sights for $49, I would buy them but fitted all my glocks with hi-vis fo sights.
The tool that came with mine is a very small very short straight screw drive. No actually a screw driver, just a small black plastic handle with a small flat blade.Be sure to use the correct rear sight tool. You'll need to use an angled tool and not a straight tool.
It's all good. I knew you'd figure it out.Sorry, I thought you were talking about the adjustment tool, not the install tool. My bad.
