The following installation is for the Ameriglo Ghost Ring Plain GL-122 sight set installed on my Glock 19. I chose Ameriglo over the Aero-Tek Tritium Ghost Ring Night Sight Sets For Glock solely due to the price. The Ameriglo Ghost Ring costs around $30 while the Aero-Tek Tritium Sights cost about $95. I reasoned that I did not need the tritium feature since I would be shooting my gun in a well lit indoor range. If I ever did have to shoot the gun in self defense or low light conditions I would point shoot and not use the sights anyway.

My new Ameriglo sight did not come with any installation instructions. The following installation instructions are what I pieced together from various internet resources. I did not have any sight installation/removal tools for my installation. I used just what I had around the house.

Glock Sight Comparison - Factory Sights Verses Ghost Ring Sights

The following pictures compare the Glock factory sights for a Glock 19 against the Ameriglo Ghost Ring Plain GL-122 rear sight. They are shown in comparable views. The original factory front sight is shown in all pictures. I did not install the front sight that came with the Ameriglo set because it was all black and had no white or colored sight dot. It was just a plain black front sight which I did not like. Since there is only a .04" difference in height between Ameriglo's front sight (which is taller) and the Glock factory front sight, I am hoping I can get by with the factory sight. Update: Later on I discovered that the .04" difference in height was too much and I had to install the Ameriglo front sight. I painted my own white dot on the front sight.

  1. For tapping out (removing) the existing rear sight, use an aluminum or brass rod so you won't mar the surface of your new rear sight. Even though it's not shown in many of the pictures I placed masking tape over the end of the rod to further minimize marring. The softer aluminum or brass rods should not hurt the steel sight but they may remove some of the bluing or finish off of the sight.

  2. Some people use Loctite to keep the sight in place. I chose to clean and lubricate the channel on the slide as well as the new ghost rear ring sight as the tight friction fit will not allow it to move. It was a tight fit, even after I filed the dove tail down on the new sight.

  3. This was the hard part. The fit was so tight that I had to install and remove the sight several times before it would go all the way in. Between each installation I filed (very small amounts) the dove tails of the new ring sight. It was done on a trial and error basis. File a little, check the fit, file some more and so on until I was able to install it all the way. I ended up removing and installing it 5 times before it would fit and it took 80 swipes of the file (very light pressure) on each dove tail to make it fit well.

  4. With all the pounding that I did, the wooden jig loosened up a little so I had to shim the slide using paper towels (not shown) to get a nice tight fit.

Testing the Glock 19 Ring Sight At The Range

After shooting my Glock 19 with the Ghost Ring sights for over 2 months (and 1,000 rounds), the front one came loose. Here is the related correspondence I had with my friend about it.

February 2, 2012
I just cleaned my Glock 19 and noticed that my front sight came loose (the one that I installed). It is held in with a internal screw and Loctite. It occurs to me that this is a potential failure point. It the screw should wiggle loose and fall out inside the slide it could get caught in the rails or get batted around by the barrel and cause damage or malfunction. I will have to think about this a little more.

It should not get loose with Loctite if the surfaces are clean. Do you have more Loctite? If so, clean all threads with alcohol and reassemble. I had the same problem with my Ruger MK III but after disassembling the sight, cleaning it and reassembling with Loctite, I have not had a problem. Also a loose front sight will have a very detrimental effect on accuracy. I would expect a SIGNIFICANT improvement next week!!! Carl

I just finished doing that but I do not have the proper tool, a sight installation wrench. My "modified" socket wrench is the right size but doesn’t fit properly into the cramped space between the hex and the slide wall. I did the best I could for now. I will order the correct sight wrench tool (Wiha Nutdriver, Precision, 3/16", 6.1" OAL as well as Henkel 01-24200 Loctite 6-ml Threadlocker 242) and do it up right. No wonder I was “off” today.
