I have installed Meps and factory sights on my G17 and believe me this does not require any special install tool.
Put the slide in a towel and secure in a vice and tap the old sight out with a wood dowel and hammer.
Install meps the same way. If the rear sight is not going in easily, dress the edge with a small file. This only takes 2-3 minutes to do. If you go to Glock Talk you will see that many gunsmiths use this method.
You also want to put a drop of loctite on both sights.
A minor point for the threaded front sight which differs from the instructions. Put the screw in first and hold in place with one finger and flip slide over and mount the sight on the screw and start turning to start the thread. This is much easier.
