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

I was taught at an LEO training by a Glock armorer many years ago to let a small drop run down each rail of slide and put a small drop on the tip of the ejector. I always do a lot more.

I've used Mobil 10w30 on most of my guns for more than 15 years. I apply with a syringe to rust-prone parts and small parts that don't move much. Works excellent, cleans off easily with a blast of brake cleaner, and price cannot be beat.

That said, I've become a big believer in Ballistol and have started using it more and more on some of my pistols, and I wonder if its properties might mitigate the issue described by the OP.

I hear less about TW25B these days, but I still use it a lot and find that it sometimes can work wonders on trigger mechanisms.

I love Ballistol but I also love the very lightweight synthetic motor oils that most of us have about the garage.

I have fallen for the hype before. Yes, I still have some of those little pipettes of frog lube somewhere. Nowadays I just use whatever is easy and cheap usually motor oil, grease, or some mixture of the two.

This doesn’t sound like a Glock problem. It sounds like a gummed up old lube problem.

I have never run ANY firearm dry and cannot imagine not having some kind of lubrication in the rail channels, barrel/hood area at a minimum.

I’ve used everything from high end cleaning and lubes to 3/1 oil at times and never had an issue. Currently I use a mix of ballistol, a Wilson branded grease/lube and super lube. (I don’t mean mixed together just the different products in my cleaning bag)

I’ve used Ballistol for many years now and never a problem with it beyond it smelling like dirty hobo feet fresh off a cross country train hopping run.

I have used TW25B on a few occasions and found it would turn yellow and thicken over time with a couple of my safe queens that don't see regular use.

I don't know, I've been using Weapon Shield for probably 15 years or so, the originator was the guy who developed FP-10. Anyway, it has always worked well for me although I have never put the rounds through any one pistol as much as some here have.

I don’t know if this applies to oils, but I an industrial application we were using calcium based greases in some valve actuators and lithium based in others. Both were fine on their on, but when someone mixed the two in a few of the actuators, the mixture stopped being grease and hardened up to the point it had to be chipped out.

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.

Probably the biggest change effecting the trigger stroke from gen 4 to gen 5 was the block, so that was where we looked in few cases (the original Glock striker safety was too tight and when it hung up it got really exciting, thus the 6 part upgrade in the mid 90s).

Sometimes these things are a leading indicator of sorts, sometimes they aren’t.

When the (iirc) Indiana highway patrol got G22s and put lights on them they reported reliability problems which could actually be replicated.

TX DPS issued M&P 9mm’s for about 1 day to one basic class, declared them unreliable and went back to sig P226 DAK 357s. They could never replicate the described malfunctions to their command or IG, but the damage was done so they got P320s.

When our first guy showed up with a gen 3 Glock that had a serial number starting with “e”, we accused him of doing something to make the rear slide rail break off. Later we found out that Glock had adopted a new process for bending the slide rail piece which was causing intermittent fractures, so they did a frame replacement recall.

The jury is apparently still out (everywhere but Milwaukee) on p320s going off in the holster.

The lack of accuracy around beretta 96s was considered a lack of trigger control until they changed the rifling twist and stabilized the bullets.

Early 2000s, a whole pile of S&W revolvers saw barrels breaking off at the frame until someone at s&w realized they had begun to overtorque the barrels during installation (I still haven’t figured out what they changed, but it could have been as simple as one worker doing it wrong).

Jljones initial post was along the lines of “anyone seen this?” It’s a non safety, non reliability related variability in performance. Many of the above started with conversations about “have you seen this?”. Sometimes these conversations may be useful to the manufacturers when they get this feedback.


Also, you are far from a mere commoner, you provide the conduit through which these conversations can occur.
