TruGlo TFO Sights with GLOCK 42

Recently, while looking for something new, I contacted J&L Gunsmithing for advice. As usual, Jim had the advice and expertise to handle the build I wanted. Among the recommended upgrades to the stock GLOCK, was TruGlo Brite-Site TFO sights. The build was for a GLOCK 22 and mimicked the upgrades from the majority of J&L’s SWAT customers.

Chesapeake, Va. Jim Jones provides a wide range of firearm services, including trigger jobs, gun prep for USPSA, IPSC, IDPA and 3-gun competitions for the divisions you are shooting; Certified Cerakote Application; firearm manufacturer, and custom builds for box magazine-fed shotguns; custom builds for AR platform rifles in multiple calibers; and pistol and rifle rechambering.

When I received my upgrade, I greedily opened the package and inspected the G22. I was pleased with the sight, but not overwhelmed. Of course the inspection was under fluorescent lights of the shop while processing the customary 4473 paperwork. Having been an archer for many years and a long time fan of TruGlo’s fiber-optic products, I thought the new sights felt comfortable but lacked any personal wow factor. The same cannot be said for customers looking over my shoulder. While inspecting the sights and discussing their merits with a friend, a group of patrons quickly formed. Before I knew it, just about everyone in the shop was handling my new GLOCK. And within the hour, three more customers purchased TFO sights.

TRUGLO GLOCK 42 sights
CNC-machined to tight tolerances, TruGlo’s TFO sights are a great upgrade to any platform.

Under natural light at the range, the sights really popped and showed significant advantage over competing night sights and traditional three-dot models—even though it was in daylight. However, it was at home in the dark that the TFO sights really shined and proved their worth. In the dark, I’d put these sights against any other model in the TFO’s class. Take a look, and you will understand.

TruGlo constructs TFO sights using fiber-optic rods that collect ambient light to provide bright, clear aim points under any conditions, with natural or artificial light. They feature a sealed Tritium cup that provides artificial light to the fiber-optic in complete darkness, which gives the shooter a reliable aiming solution under any condition. Even under the darkest conditions, the TFO’s sight picture was bright, without being so bright they overpower the shooter’s night vision or create a halo effect around the fiber-optic that would degrade the sight picture.

The Tritium cup is well seated into the CNC-machined housing to ensure it will not give away your position in an emergency. Tritium is a radioactive isotope, which sounds scary but is not. Tritium has been used in sighting systems and wrist watches for decades. If you feel a compelling desire to eat either one, well …

The important part is that tritium is not dependent on ambient light to recharge. That means a firearm equipped with TFO sights and stored in a bedside safe still will be ready for action anytime.

The GLOCK 22 is a full-sized pistol. The combination of the G22 and TFO sights make sense for a SWAT team member entering a dark environment as much as they do for someone relying on TruGlo’s TFO sights at night for home defense. That logic made my decision a no-brainer for the GLOCK 22. Somehow, inexplicably, I did not immediately apply the same logic to pocket pistols.

I have often regarded subcompacts as guns with sights that were not as important. The loss of a couple inches of sight radius degrades accuracy significantly by comparison. The short-engagement-distance subcompacts are for left me with the impression that rudimentary sights were sufficient. Then, someone brought it to my attention that since when is “sufficient” the standard by which we should gage equipment on which we were going to depend in a life-threatening situation?

TruGlo Brite-Site TFO sights deliver a reliable sight picture under any lighting condition, including total darkness.

If a subcompact pistol were going to be the only gun I was carrying, or even the backup, why would I want less than the best? What would happen if I was carrying and forced into a dark environment when I needed to engage an active shooter to defend my family? Take the scenario of a movie theater, a smoke-filled room or other environmental factor, how much value would you place on self-powered night sights then?

I guess that is why pocket pistols, such as the GLOCK 42, are now wearing TruGlo’s Brite-Site TFO sights in record numbers. Shooters and self-defense enthusiasts do find value in solid, reliable aiming systems—regardless of the size of the platform.

At the range, the TFO sights proved their worth in a head-to-head comparison test. Leaning from my experience of the past, I choose green/green fiber-optics, although TruGlo offers other combinations. In my experience, green fiber-optics simply offer the best light transmission under natural light and when powered by Tritium. Other colors do perform better under fluorescent lights; so do not be too quick to judge.

  1. Respect to all shooters here…Military, NRA, etc. In my humble opinion, this is not a place to brag about qualifications. The way I see it, in a CCW scenario, your fighting scenario will be for survival, not kill, within 0-3 yards, up close and personal. If your aggressor dies in the confrontation, so be it but with laws, one must be careful beyond 3 yards. One has to protect themselves not just with lead but also your interpretative rights. Question, Why would you shoot beyond 3 yard, unless you are in a gun fight which it wouldn’t matter what sights you have, what caliber you have, what round you stuff and puff? Throwing lead down range in that case will get one in trouble. So, 0-3…pull only if you are going to shoot but be sure the reason you pull is a good reason. If you have to take time to aim, three dots across, etc. may be the wasted seconds that causes an uncomfortable result. Practice your defensive fighting postures/action. Pull and shoot…with maximum results. If you know what you are doing, your equipment should not fail you in a danger close scenario regardless of weapon types, ammo types, etc. What works for you for your survival may not be the same as someone else. Practice. Be prepared. Just my two scents

  2. And, I assume, With All Due Respect, many, even in the forum are unaware of the bottom line in a self defense situation. No matter where you are in a “Life Threatening Confrontation” the threat is in fact, “The Enemy”. There are two types of enemy… Those that have been properly dealt with and Those that are still alive.
    Never draw a weapon unless you intend to use it. Never point a weapon at another person unless you intend to shoot them. Never shoot at another person unless you intend to kill them. If you aim a weapon at some one else, you raise the stakes. If they are willing to back down, well and good. If not, and some people won’t, they may decide to go for broke. If they have a weapon, they will use it. If not, they will try to take yours. If that happens, they will probably use it on you.
    So, never think for a second, waving a gun at someone will make them do what you want them to do.
    The flipside is… You had better be sure “Damn Sure” your ” Life ” is in danger before escalating the confrontation. If there is “No Question ” in your mind their actions justifies killing them, then you shoot, not to wound, you shoot to kill. If you are justified, your sole intent is to neutralize the individual. The quickest way to do that is to kill them.
    Take a good hard look in the mirror. Does that person have the strength, the will and the “intelligence” to make the shot.
    That said… Proper Siting is “Vital”.

  3. Well, you are correct, in that, my stock sites are not adjustable. Out of the box the only adjustment necessary was to elevation, windage was perfect. Trying to file adequate material from a fiber optic site for the same purpose would be problematical at best. The first 1911 style hand gun I owned required replacement of the stock rear site with one having adjustable capabilities with the “Dovetail” “Fully Engaged”. Drifting a site in the dovetail is certainly not recommended. Had my current “go to” piece needed windage adjustment, it would have been replaced.

  4. My G26 has the yellow rear and green front. By far the best upgrade you can do to your Glock. I believe it improved my shooting accuracy. Not a fan of the stock U-sight. Nice and bright in full sun, low light and darkness. Highly recommend the TFOs over other night sights and I’ve owed quite a few.

    1. I just wanted to explain the reasoning for going with the yellow/green combo…
      In a competitive or defensive shooting situation it’s all about hitting your target as fast as possible. You should only be concerned with your front sight post being aligned with the rear and having it on target. Your focus is on the front and not the rear which will look blurry. You want that front to really stand out and pop this the reasoning for getting the bright green color up front and the duller yellow in the rear. My 2 cents.

  5. Jim,
    Color choice, of course, is a personal matter. I went with green/green based on two factors. First, in a head to head test, the green sights were simply brighter. Shooter have successfully used three white dots without confusion, so all green did not present a worry. Second, I know more than a handful of SWAT guys using this setup. Everyone of them use the green/green combo. Its not proof, but one more tick in the pro column for green/green in my opinion. ~ Dave Dolbee

  6. I have the Tru Glo sights on my G19 for my home defense weapon. My wife has a G42 and it has stock sights, so far. I may upgrade that in the near future. I also have the G26 and this is my primary CCW. It has stock sights. But may go with the Tru Glo, and instead of the yellow/ green, I would go with all green for the next one. The yellow is just not as bright. I thought it would be better in the dark to have 2 colors but now I’m not sure, I like it. I don’t do a lot of dark shooting. The Tru Glo do not really light up in low light. They are great outdoors or in the dark, but in a low light room, no overhead light, they are worse than the stock sights.

  7. You are obviously unaware of NRA qualifications. All target “Are” at self defense ranges. Without proper siting even at those ranges a wounded individual can return fire, a dead individual cannot. “Proper Siting” is a critical element no matter the range

    1. You are obviously unaware that NRA EXPERT CERTIFICATION isn’t required to successfully defend yourself with a gun.
      You state that you have no use for non-adjustable sites yet your own “go to piece” either doesn’t have adjustable sites or they weren’t adequately adjustable to prevent you from having to file off the front site. That seems like a contradiction.

  8. Larry- These sights are not going on a target gun and the Glock 42 is more of a “get off me” gun rather than a 25 yard gun. I see these sights for use on a concealed carry gun or for home use.

    You can drift the sight for windage, and elevation should be pretty close.

    In my opinion, all carry guns should have night sights on them. If you can’t see the sights at night, it won’t matter if you can shoot NRA Expert or not.

  9. I use these same exact sights on my Glock 27 and love them.

    I chose a yellow/green combination, yellow in the rear and green up front, as this allows me to be 100% sure I have it aimed right in darkness because I’ll see a green dot between two yellow dots.

    With a green/green combination I feared that in the heat of the moment I might possibly misalign the dots and not know it…just seeing three green dots in a row.

    And yes, green rocks as our eyes are more sensitive to green!


  10. All well and good except for one thing… Every handgun I have ever used has it’s own “Point of Aim, Point of Impact”. On my personal “Go To” piece (Springfield V-10 Champion) I had to file 4-5 thousandths off the front site blade for “Expert Accuracy” with stock sites. Nowhere in the article or evident in the pictures do I see or read about adjustable capabilities. Without that ability, it doesn’t matter how good the optics are if I have to use “Kentucky Windage” to make an accurate hit. With that in mind… I have no use for those sites.
    I am a NRA CERTIFIED EXPERT with my 45.
