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.

Two, I mean Three Bad Guys

Today’s training included some close-range drills with multiple targets. After a few reps we started to regard the second target as a new bad guy who arrived late. In this drill I engaged the second bad guy and was performing an admin reload (to ensure I had a full gun after the initial engagements) and my training partner Dave yelled, “Oh shit!” So I had to go back to the gun one-handed on a “new” bad guy. Wasn’t expecting that.

Good training.

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.

IGFS Trigger

 

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.

New BCG: Rebel Arms Enhanced Nitride M16 Bolt Carrier Group

I needed another BCG and found a good deal and what looks like a nice component. I picked up the Rebel Arms Enhanced Nitride M16 Bolt Carrier Group and it arrived today. Gonna put it in my SBR and see how she runs this weekend.

Looks pretty nice. My only negative observation here is that I’m not so sure about the gas key staking. Looks a bit anemic and should probably have been more aggressive. We’ll see.

Pistol Drill: Five Inside Out

For this drill you’ve got 5 targets setup at 10 yards–three 6-inchers, a 10″, and a milk bottle. At the beep, draw from concealment and put one round on each, starting from the middle and then clearing the rest.

I did the drill about 25 times and while I had plenty of clean runs, I also had plenty of 1-miss runs; like this string of five in a row. :-/ Moar training!

Reload and Re-engage Drill

This is a simple reload drill. The target is the little round 6″ steel plate at 10 yards, third from the left.

I’ve got one in the pipe and an empty magazine. Draw from concealment and put one round on target, pistol is empty, move off of the X and reload from concealment, then re-engage the target with two more rounds. Should take less than 4 seconds.

Pistol Build 2017 .300BLK

I recently built an 8″ upper for my .300BLK SBR, but later decided I liked my standard 10.3″ upper on that one. Since I now had an extra upper assembly, I went out yesterday and bought an Aero Precision lower blank and built a new AR pistol with the spare parts I had and a Sig arm brace. Because I can. Can’t wait to try this one out this weekend!

  • Upper and lower receivers: Aero Precision (blanks)
  • Barrel: Ballistic Advantage 8″
  • Rail: ALG 8″

Flee-Then-Engage Drill

This drill supposes you’re running away from an armed assailant, then a second cuts you off and you must defend.

Draw from concealment and put 2 rounds on the 8″ plate at 10 yards, you run empty so perform a reload and put 1 round on the other bad guy while advancing on him (intimidation factor works on most folks, causing panic or surrender or sloppiness).

I did this drill about 20 times today. This run was toward the end. Good workout!

New Watch: Smith & Bradley “Springfield”

Really loving my new watch. The Springfield has a classic look, clear indicators in light or darkness, and rugged construction. It’s not an expensive watch ($175 – $225) and I think it looks amazing.

Full-Mag Fatigue Drill

I ran this drill 18 times today. “Fatigue drill” is right.

I’m setup here at 15 yards on a 12″ (not 10″) steel plate. The point is to run this drill several times in succession and maintain accuracy as you get more and more tired.

I started out with 1 miss on my first run, then had 2 per, then 3 per, and ended up with 4 misses on each of my last 4 runs. Fatigue is a thing. More training.

Near the end you can hear Gunny yelling at me about my misses. I can always count on Gunny to keep me humble, and every time I miss it seems he’s standing behind me. Usually with a comment at the ready. 🙂
