The IGFS Trigger Destroyed my Glock 19

I really like a flat trigger and have, since October of 2016 enjoyed the IGFS Enhanced Duty Trigger. In that time I put 19,650 rounds through my EDC Glock 19. This is the only trigger I ever had in this gun, as I bought the frame and the IGFS trigger at the same time. After confirming that the trigger was safe and effective, I made this my everyday-carry gun.

When I noticed last week after 19K+ rounds that the trigger safety was not engaging properly, I removed the trigger and sent it back to the manufacturer for replacement and dropped the stock trigger assembly back in. The pistol no longer worked.

While training at the range yesterday, the trigger began to fail. For the first few rounds it felt odd, but I attributed that to my not being used to the stock trigger anymore. But then it failed completely and would not reset. I got a dead trigger, where I could pull the trigger repeatedly and got no striker fall. Then, after a few pulls, the striker would fall and the pistol would shoot.

I immediately disassembled the pistol and inspected the components, trying to diagnose. Others at the range, familiar with Glocks, joined in; all of us trying to discover what was going on. I carry a components box so I replaced the connector and the trigger spring in succession, and even put a drop of lube on the connector/trigger-bar intersection, re-trying the pistol, in an attempt to find the failure. No joy.

I noticed that the trigger pull articulated 2 clicks: an initial click, then the striker fall. This would prove to be the telltale symptom.

Each or us inspected the frame and slide components, trying to find the culprit. At last, my friend Jason had an epiphany and asked to see the stripped frame again. He looked carefully into the trigger guard and said that he found the problem.

The depression created by the repeated pressing of aluminum against the polymer created a ridge that blocked the stock safety tab from allowing the trigger to reset. The deformation of the polymer can be seen by examining the proper line the polymer in that are should take vs. the line created by the aluminum safety tab:

You can see there how the depression creates a ridge that rises above the proper line for that area of polymer.

Next Steps

So that I could again have a functional gun, I took a small file and removed the damaged-area: the ridge created by the IGFS trigger safety tab. Even so, the damage has been done. I believe it is only a matter of time before the safety mechanism no longer works. A stock trigger now functions, but it feels different. The reset has no telltale “click” like a normal Glock trigger should. So I now have a question every time I pull the trigger. “Will it work this time?” That’s not what a Glock pistol is supposed to give you. Rather, a Glock is supposed to give you 100% certainty; certainty now destroyed by the IGFS trigger. Needless to say, this is no longer my EDC gun.

Luckily I have another Glock 19 frame to use for my EDC. As I now await my replacement trigger from IGFS, I believe I should NOT put it back into the frame. I think this frame is now forever ruined. This is what happens when aluminum abrades polymer. In other words, Innovative Gun Fighter Solutions has a severe design flaw that they must fix, as their trigger will destroy every pistol into which it is installed.

Other Brands of Replacement Triggers

I notice that every flat-face replacement trigger on the market has an aluminum shoe and aluminum safety tab. I cannot say for certain, but it is possible that EVERY replacement trigger will destroy the polymer frame of the pistol. If so, this is bad news.

I don’t have the $ to test every replacement trigger to 19,000 rounds, but I believe every manufacturer should troubleshot its design and ensure their triggers are not destroying otherwise 100%-reliable guns.

IGFS Enhanced Duty Trigger – Failure After 19K Rounds

Since October of 2016 I’ve been running the IGFS Enhanced Duty Trigger in my EDC Glock 19. The action and function of this trigger was excellent and I was very happy with it in my carry pistol. The flat face makes for a more consistent press action and I find it easier to employ proper mechanics than with the stock Glock trigger.

While doing dry-fire practice this week I noticed that the trigger felt different and took a good long look at it. That’s when I saw that the safety tab was rather shallow on the trigger shoe. I confirmed that the safety mechanism no longer prevented the trigger from being improperly pressed to the rear. Not good!

This is the promo photo for the trigger. Notice that the safety tab protrudes prominently.

 

Here (below) is my IGFS Enhanced Duty Trigger after being installed on my Glock 19 last October. Notice here that the safety tab is prominent. I did confirm then that the safety mechanism worked properly.

In the seven months that followed I carried this pistol all day, every day, and trained with it 3 to 4 days per week. I shot 19,000 rounds in that time and thoroughly enjoyed the trigger.

But here (below) is the trigger today after 19,000 rounds, 7 months after installation. The trigger safety no longer protrudes enough to keep the trigger from improper engagement. I inspected the trigger assembly for any impediments or damage and could find nothing. My conclusion is that the spring that engages the safety tab just wore out from use.

 

As you can see here (below), the trigger safety should be protruding more in the front so that the rear catch is exposed enough to engage and prevent the trigger from being improperly pressed to the rear.

 

Here (below) you can see where the mechanism is supposed to be when not engaged. Thousands of trigger presses just wore out the safety spring. No bueno.

IGFS Trigger fail

I contacted IGFS and told them about this. they responded to say that they’ve never heard of such a failure and will replace the trigger. That was a few days ago and I have no return or replacement details yet. I will report when I know more.

I like the IGFS Enhanced Duty Trigger and would like to continue to run it in my EDC gun. But I’d like to know that they’ve addressed this specific issue. This trigger is specifically for Glock pistols, which are known for 100% reliability. This component would not seem to fit the standards. For now it’s back to the stock Glock trigger that came with this pistol. I have stock Glock triggers with 60k+ rounds of use that exhibit no safety malfunction whatever. IGFS should do better.

Glock 19 Report: 30,000 Rounds In

Glock 19 Report: 30,000 Rounds In

I purchased my Glock 19 Gen4 in mid December, 2013; just about one year ago. In this past year since purchase, I’ve put more than 30,000 rounds through it in training and competition. In those 30K+ rounds, for every round I fed into the pistol, I pulled the trigger it went “bang.” Every round fired every time.

While most of the ammo I’ve fired through this pistol was Federal white box and Freedom Munitions 115gr ball ammo, and a lot of Copper-Matrix NTF frangible rounds, I have also fired hundreds of defensive rounds from Remington, Federal, Winchester, Hornady, and Speer—including hollow point and plastic-filled/tipped rounds of 115, 124, and 147 grain.

With every brand, grain, and type of round fire, not even one single failure:

  • No stovepipes
  • No failures to feed
  • No double feeds

There was a stretch around 10,000 rounds or so where I tried an after market recoil spring that turned out to be too light for this pistol. The result was a tendency to delay going into full battery for a second or so after some shots. I remedied this issue by going back to a stock recoil spring. Even in that period of after-market folly, every round chambered and fired (and never an anomaly of any kind using a stock spring).

With 30K rounds fired in less than one year, that means that I’ve fired at least 600 rounds per week, every week, with just this pistol; one of several that I own and train regularly with.

Parts Replacements

As is advisable, I have replaced the recoil spring a few times (two of those was with the aforementioned and ill-fated after-market springs). The current spring is only a few thousand rounds in and is a stock, Gen4 spring. As this Glock 19 is my primary competition gun, I replaced the trigger connector and springs in favor of a 3.5 lb setup after about 10,000 rounds. I have replaced the trigger spring twice, each after about 10,000 rounds (and it’s likely time to do so again, now). I also replaced the slide release lever with an extended model, yet find I almost never use it.

While I don’t mind the configuration of Glock’s stock sights, I do not like or use plastic sights so I replaced these with Glock factory tritium night sights. Sights have to be durable and stand up to punishment. Iron over plastic every time.

Report Conclusions

I believe the Glock 19 is an almost perfect pistol, given its reliability, size, capacity, concealability, and general suitability for everyday carry and for competition. Given the competition-friendly modifications I made to mine, I no longer use my Glock 19 as an EDC, but I use it a couple times a month for competition and train with it quite a bit at both the target range and the practical range.

I’m a bit fastidious with regard to cleaning and upkeep, but my G19 functions as well and looks as good today, after 30K rounds, as it did when it had just 500 rounds through it. I would recommend the Glock 19 as anyone’s first pistol purchase and as a must-have for every pistol enthusiast’s collection.

Armed Confrontation Survival Course

On Saturday I participated in the armed confrontation survival course offered by Brian Harpole and his staff from Consolidated Training Group. It was an all-day class held at the Proactive Defense range in Argyle, TX.

The class was lots of fun and very well run, I thought. It was also very revealing.

As described on the CTG site

The Armed Confrontation Survival Course focuses on quality, practical training that has real world and situational transference. This course focuses on developing a survival mindset and aggressive weapon handling techniques, while sharpening concepts of threat visualization and reflexive reaction skills. This one or two day class (8 or 16 hours) is applicable for Military, Law Enforcement, Contract Security and Responsible Gun Owners. Topics have immediate relevance to the day-to-day functional activities pressed upon us, and lead directly to the development of specific action steps for immediate life implementation.

We started with marksmanship and gun-handling assessments at varying ranges, then built up to more practical situations. None of the practical drills were static; all involved either an evolving situation, physical requirements in the midst of defense, moving from cover to cover, or having to defend from inside and around a vehicle.

More than half of the drills required us to make critical threat and/or environment assessments and respond according to the new threat or non threat.

This was an exercise where we defended from cover against one assailant, then had to assess the environment to defend against one or more additional threats that appeared at the instructor’s whim.

The latter portion of the class was concerned with dynamic, real-life scenarios in which we used live-fire with Simunition FX ammunition in otherwise real weapons against a real person. These were, by far, the most mentally challenging drills. Each scenario was different and a complete surprise to the student.

There was no instruction; you just entered the scenario with a specific task—”You’ve just arrived home and are going to your door…” or “You are at a store checkout counter…” or “You have just rear-ended another motorist in your car…”—and the situation unfolded with you in it.

I think it notable that in each of these scenarios there were usually moments where the threat was real, but did not warrant deadly force. At some point, however, things changed and deadly force was appropriate to stop the threat to yourself or someone else in the scenario. These were challenging scenarios and it was unnerving to point a real weapon at someone and pull the trigger. See for yourself…

My Conclusions

Brian and his staff did a great job and put together a fun and challenging class. I’m glad to have taken part and I’ll be doing more of these kinds of classes in the near future. I was reasonably happy with my marksmanship, but my lack of experience in these sorts of dynamic, practical, evolving scenarios left me disappointed. As a CHL holder I want to address this gap in my training for, like most people, I lack what I consider to be requisite competence in dealing with the breadth of threatening situations one might be confronted with on any given day.

The result of one’s performance in a threatening situation will have a result that is permanent. Tentative or unpracticed decisions and actions would be detrimental for all involved. I’d rather respond with a practiced eye, spirit, and resolve. That means more training.

If you’d like to prepare for real-world threats and challenge yourself, visit the CTG website or their Facebook page and see what they offer. Sign up for a class or two or six.
