I'm not sure, but I know it's doable. I just laid out my key set and trial and error. Sorry I'm no help.

I have done several, installing Firesights on the dovetail models of the MilPro.

To remove the REAR sight takes a 2mm hex/Allen wrench.

The FRONT sight takes a 1.5mm hex wrench.

SOME of the sights that I have removed had the set screws very tight with a LocTite type sealant.
Use a GOOD quality 1.5mm wrench to remove the front sight because some of the cheap hex wrenches rounded off rather than removing the set screw.

If you install FIRESIGHTS, they take a .05 inch allen wrench. I bought them in quantity on eBay.

This is correct. Be gentle with the front sight. This small of a hex head will either round out the hex driver (if you're lucky) or the screw head (if you're not) easily. Be sure to apply steady pressure into the screw head while turning.

Would anyone happen to know the dimensions on the front sight for a 709 slim? I'm trying to find an aftermarket night sight with similar dimensions. It's my understanding that there is one for glocks that is pretty close to a perfect fit with minimal or no filing.

Or, you could be unlucky like me, go out and buy a high quality 1.5 mm allen wrench, pick all the locktight goop out of the hole and then find out that the set screw must have been rounded out during install at the factory :(
Oh well. I'll eventually figure out how to get it off and get my new front sight on.
