What are the best affordable tritium and fiber optic sights for Polymer80 and Glock pistols?

A fellow emailed me wanting to upgrade his Polymer80 from the generic OEM Glock sights that I don’t think really excite anyone to something that would be more visible in general and also work in the dark. My answer was immediate – go with the TRUGLO TFX Pro Tritium and Fiber Optic Xtreme sights.

The featured photo above shows how bright they are on my P940CL that has a G17 slide on it. I bought these sights by the way – so you are getting my honest opinion.

Folks, these are my hands down favorite sights for a number of reasons:

  • They are CNC machined from steel and have a durable black nitride finish — they are not soft plastic.
  • They do not need batteries – the lit dots are via fiber optics when there is light and sealed tritium when it is dark so you are covered regardless of the light available. The tritium ought to fluoresce (emit light) for about 10-20 years and I’ll worry about replacing them then.
  • I really like the three green dot configuration – two on the rear sight and one on the front. The front also has an orange ring that you can see when there is light but is green when operating off the tritium only.
  • The rear sight goes into the slide’s groove very easily and is then secured with a set screw. Some sights can be a bear to install but not these.
  • The rear sight is big enough that it can help you rack the slide one handed in a one-handed emergency.
  • They have a 12 year warranty.
  • They are assembled in the USA – the tritium capsules are made in Switzerland.

What Glock models are supported?

Because these are so popular TRUGLO is making a variety of models to support the different Glock and Polymer80 configurations that are out there. I assembled the following table and you can also check their webpage if you want:

Personally, I use the TG13GL1PC on a G17 and G34 built on PF940v2 frames. I bought both off sight sets off Amazon and the following ad will enable you to order any of the above as the models are listed as options:

This gives you a better view of the sights overall. This is the TFX Pro TG13GL1PC with the fixed rear sight. I really like the sight picture these give day or night.
Here’s the rear sight and you can just barely see the set screw that secures the sight between the two “ears”. The slot at the top of each fiber optic is where it collects light to illuminate the dot. If there isn’t any light then that is where the tritium capsules take over.
Here’s the front sight. The orange ring is nice during the day and you only see the green tritium dot in the dark.
Well, trying to take a photo in the dark of three green dots with a cell phone camera was an experience. I went in a basement room and shut the door to cut off light. It’s fuzzy but you get the idea – all three dots are nicely lit in any lighting condition.

Do they have lower cost models also?

Yes, they do. The Tritium series just has the tritium for illumination in the dark and show as bright white dots during the day.

The following Amazon ad will lead to all of the above models as they are options you can select:

They also make a Tritium Pro series that builds on the Tritium base model and adds an orange ring to the front sight plus the back sight is bigger and that makes it easier if you need to rack the slide with one hand.

Definitely. These are very popular lights given their great combination of quality at a fair price. I tend to see the best prices on Amazon so use the following search to check what they have:

Conclusion

I hope this helps you out. I really do like these sights and have no reservation recommending them.
