I just finished installing my new set of Ameriglo Pros on my G17. They come with the front sight tool. I happened to have some red locktite on hand, so the install only cost me a bit of time. For the rear, I pinched the slide between two pieces of wood nailed to my workbench to make a poor man's vise. I then used a brass punch to drift the rear sight in. It got stuck about half way, so I backed it out and took a tiny bit of metal off of the bottom of the sight with some 400 grit sandpaper. I was then able to drift it in with a good tight fit. It still took a fair amount of hammering. You want a good tight fit so the sight won't move unless you hammer it. Luckily, my vials survived the operation and my sights look great. I LOVE the sight picture on these Ameriglo Pros.
These are my first sights with Trijicon elements. I've used Meprolights in the past, and I have to say that I like the Trijicons better. Though smaller, the dots are much sharper and easier to focus my eyes on in the dark. The Meprolights on the other hand were always a but fuzzy looking in the dark and not as defined.
