To the OP. Were you using Lucas grease or the blue oil ?

Red and blue lube

Ok. I’m just trying to figure out what oil has to do with the trigger pull ? Or am I missing something in the OP ?

I think they’re saying that Lucas oil can thicken up/gum up and cause issues with the gun. That’s good to know since I use Lucas oil for my guns.

Are you saying it’s doing what it should or not doing what it should?

I have 1 Gen 5 G17 with just over 5k and have experienced no issues.

My wife’s department issues Gen 5 G17 and there’s been no related issues.

I have heard of problems on the internet in regards to this, but I’ve never heard of what causes it.

When I assemble my guns after cleaning I ensure the striker channel is clean and free from lubricants, I add a small drop of CLP to the trigger bar that contacts the slide release as well as the part of the trigger bar that rides in the slide and moves the striker safety up.

As a formulator of lubricants for 20 years I would carefully and diplomatically suggest that we avoid lubricants from brand L.

Thanks for posting this. Just a recreational shooter here but this thread has given me habits to reconsider (no, I don’t use the L brand).

What are your thoughts on the lubes offered by Wilson Combat ?

Never had problems with CorrosionX CLP or regular CorrosionX as lube on all my stuff, including a Glock or two.

1. I thought Glocks are rated and designed to run dry??

2. Anyone run a Glock (or any other pistol) using 0W30 synthetic motor oil??

The idea that Glocks should run dry was foolish marketing, at best. I don’t know any machine that works at performance levels dry metal on metal, or “place a drop of oil on a Q tip and run it on”. The last armorers class, the instructor used ample amounts of CLP. Glock recommends lubrication in the armorers manual. To each their own.

I can’t imagine running 20k a year down the pipe like I do and try to do it “running it dry”.

I foolishly use a dab of grease in certain spots and plenty of oil. Not as much as I use on the CZ but more than shown in the manual.

I don't know anyone who runs a Glock dry. Certainly, it has been and is being done, but only by those who would fail to lubricate any firearm, and the Glock will be more tolerant of such neglect than other pistols.

I don't recall Glock ever suggesting that anyone refrain from lubricating their pistol.

In addition to the lubrication points shown in this illustration from Glock, I place a drop of lubricant at the 4 rail guides on the frame; front and rear, left and right. I then rack the slide several times and remove the excess which exudes from the rear of the slide rails (and if you've used sufficient lubricant, there will certainly be some that comes out immediately after lubrication), and on the forward portion of the chamber hood. Then, I lock the slide back and wipe the feed ramp and breech face to ensure that no lubricant has gotten onto these surfaces. Insert a loaded magazine while the slide is locked open, drop the slide via slingshot and again remove any excess lube which appears at the back of the slide and on the forward portion of the chamber hood.

I should clarify, not intentionally run dry, but still function thru lack of maintenance. Most members of NYPD uses Glock and it would not surprise me if donut powder is found on the inside rails. They probably lube their G19's once a year during qualifications.....

And again, that being the case, the Glock is the pistol for them. The lack of full-length slide rail bearing surfaces on the frame is one of the reasons Glocks are tolerant of such neglect.

Off topic, as someone who respects your experience and opinion on such matters, would you say that's just related to their firearms products?

Or is that brand L in general?

Not trying to draw you out; genuinely curious.

Thanks.

ETA: My gen 5 G19 on CLP is nearing the 5k mark, and so far so good. Zero issues with my large scale sample of one.

I suggest militia 1 grease in that application.

We don’t require gen 5 glocks for those who use glocks but have seen a difference in the consistency of the gen 5 triggers (they are either much better, or much worse).

I have also seen the issue you described on a couple of out of the box basic class guns.

It is weird because there is no visual indication of roughness, galling or nickel plating failure when it happens.

It also does not happen with earlier generations, so I have examined on occasion if the firing pin block is hanging up and couldn’t find anything.

I've used synthetic motor oil on my pistols for years and all run smooth as glass.
One of my two Barsto Barrel Glock 34s has at least 35,000 rounds through it and never had an issue.
I also have a Wilson Combat Accu-comp LE with over 80,000 rounds. In that time, I had an extractor break at around 35K or so. The hammer started falling to half cock at the 80,000+ mark. Pretty damn good considering it had a 2.5 lb. trigger to start with.

I have always added extra lube during range sessions every 200 or so rounds, sometimes sooner. That may be part of the reason for the good results.

Well, maybe it's because the gen5 pistols have that "jelly frame" thing. Remember? You know- a few thousand rounds in a gen5 and then the accuracy goes to shit? I love how the self-satisfied pseudo-scientists on a certain "pistol forum" had temperature guns out on the range after the mass psychosis of gen5 pistols degraded accuracy. "Well, Chet, I'm getting readings of 156.6 degrees Fahrenheit. How about you?"

Remember the hullabaloo about Glocks of a certain vintage spitting brass in the face of shooters, and all the "testing" that went on with that? That was, what, eight, ten years ago? What ever happened with that? All those pistols are still out there but you never hear anything about the issue. Anyone care to speculate as to the reasons why this appeared and disappeared so quickly?

Don't misunderstand me- I'm not saying that there is not some sort of odd issue with the triggers of some high round-count gen5s, but I notice that jljones' issues went away with a thorough cleaning, a bit of polishing and a change of lubricant to something not prone to gum up.

I'm a mere commoner, a peasant. I'm not a sponsored shooter and I don't work for a police agency. I have to pay for the ammunition I consume, and I own enough pistols so that no single one of them will ever reach a high round-count, so it's likely I'll never encounter this trigger issue with gen5 pistols. I'm simply saying that I can't read this thread without thinking of jelly frames and ephemeral BTF issues.
