Can a trigger connector cause a G17 to run away?

[CALI SHOT DOC]

i had a 2#connector from glockmeister in my g17 to see if i'd like it for competition use. I had thrown the 3.5# connector that was in the g17 into my new g19 so i bought a new 3.5 connector(lone wolf) from midway to put in the g17 (didn't like the 2# much). I went to the range to test the new connector. I pulled the trigger, one round went off but as i was going to release and fire again, 2 more rounds went off. This happened a couple more times when i only loaded 2 rds to kinda see what was going on. When i was shooting with the 2# connector it was fine and i have 2500 flawless rounds through this gun.

I know the sear can cause a gun to run off like this but can the connector?

My G23 did this with a LW 3.5 connector. Fired on initial pull & reset. Dumped it asap and went back to stock. Only time my Glocks have EVER failed was when I messed with the internals. I keep em stock now...lol

OP,I get the impression that your situation was hypothetical,yes? Because if your Glock really did fire two rounds with one trigger pull it would be an unregistered machine gun.That would suck,since that's a federal crime.

I had this issue to with a connector from Glockworks. My issue was i had modified the trigger bar years ago for a smoother pull. It worked fine for the OEM connector but that changed with a new connector. The trigger bar "hump" in the far rear that makes contact with the connector is disconnecting prematurely before the trigger moves all the way forward. This can be cause by A: someone modified the "hump" or B: the "hump" is warn down from many rounds. I replaced the trigger bar with a new OEM part and everything worked fine. I noticed this problem at home so no rounds were fired. If I had fired it it would have fired on both pull and release of the trigger. Not a safe combo. A function test is very important when parts are swapped or modified. I will do a hundred dry fires at home before I live test a pistol.

Function test was good, thats the thing. Pull trigger, rack slide, release trigger and gun resets. I also do several dry fires when ever cleaning, replacing parts, or just doing an inspection of wear and tear. I'm going to take the trigger group apart today and inspect it closer.

Atleast the guy at the range refunded my money for the range time. Came out to the front desk, he was shocked i was packed up after 3 min and i just told him its unsafe to fire.

I just wish this happened a couple weeks ago cause i could get whatever parts i needed for free from the gssf match at richmond

yea because malfunctions never occur....

It's not a crime if the gun failed causing a runaway.

Tell that to the ATF.

A weapon that fires full auto with one trigger pull sans paperwork is an unregistered machine gun.There is no exemption for a malfunction,as a certain individual found out the hard way courtesy of the Federal Government.

Olofson was only convicted of the transfer. No one was charged with possession because prosecutors knew they were FOS. Read Jeff knox's article the accidental felon. Just because someone gets railroaded doesn't change common sense or the truth. It does suck that this is the world we live in though.

I had just gotten my first AR out of jail and at the range went auto double tap until I realized/learned the smallest spring that sits on the trigger group was missing. I learned that a function check at time of purchase would have cleared this up.
Range was fine.

I wouldnt categorize a Federal conviction as "only" anything.

We live in dodgy times as gun owners living with an anti-gun government.My only concern is that we need to show caution given that reality.

The trigger bar (specifically, the rear edge of the trigger bar) in a Glock serves the functional purpose of a sear. The length of the connector that you installed could be short enough that the trigger bar can't fully engage the striker.

First, it would be wise to remove the connector and replace it with one that has not exhibited the issue, or an OEM connector if you haven't already done this.

Next, obtain and install an armorer slide cover plate if you don't have one already. This cover plate has the bottom trimmed off so that you can see the engagement between the trigger bar and striker. Install this along with the suspect parts. You can make one from a spare plate by cutting it off below the lined area, but if you do, mark it so you don't leave it on the pistol when firing as it could move down and cause slide parts to exit into your face.

Now, rack the safe and empty pistol and note the amount of engagement between the trigger bar and striker. If the trigger bar does not have at least two thirds of it's thickness resting on the striker, try another trigger bar. Some folks will tell you to bend them, but in my experience, that may lead to the trigger bar tab breaking prematurely. Try different trigger bars until you find one that exhibits correct engagement. If the bar just barely engages, the pistol may pass operational checks but may let the striker slip off the trigger bar when the trigger is being released. Press the trigger, hold it down and rack the pistol again. Check engagement while keeping the trigger depressed. The same engagement standard applies. Let off the trigger and watch the trigger bar to see if it slips off the striker. You can repeat this with the known good parts for a visual comparison.

If you can't get the pistol to pass with the Lone Wolf connector but it passes with another connector, you know it's the Lone Wolf connector that is the problem. The connector may not be allowing the trigger bar to rise enough to get sufficient engagement.

In a word, yes. I put in a ZEV connector, and it doubled on function tests. Sold the ZEV internals that I didn't use to a friend, who's never had any malfunctions with them. I guess the tolerances just didn't stack right in my gun.

FUD

Olofson knew the gun was malfunctioning and going full auto and let someone use it anyways. There is a big difference between a gun malfunctioning and then being fixed and knowing the gun is going full auto and letting your buddy borrow it. Read up on it a little

Don't sweat it dude, it happens. I've had a couple firearms double and triple fire on me while at the range. One time it was at police range that I was invited to shoot at. AR did a 3 round burst. I shrugged it off and pulled the trigger again... BANG BANG BANG. Oh %$&$*! As long as you identify you have a mechanical issue and pack it up for inspection at home no one cares.

Function test can only tell you so much. Sooner or later you have to fire it. Sometimes you have issues. It happens.
