Looks like you're right about the rail.

The lack of finger grooves and rail are the two most obvious differences.

There are a couple of minor internal differences, which have no effect on functioning, but which mean that you may need to pay extra careful attention when buying spare parts (like the extractor).

Guilty...bought a Gen 4 19 a week ago. Took it to the range and damn if it doesn't function well and shoot good.

I came across this last night. I think its best torture video out there for the Glock.

Real issues dont start until 9:10.

Wow...not bad. Totally agree, I'll never carry enough ammo on my person to get my G19 to fail like that.

I watched that, start to finish.
I even LOLed a few times..

Nice to know my Glocks will out live me since I'm handing them down to my kids when the time comes..

I recently purchased a GEN 4 Glock 19. What is the forums opinion on weighted guide rods? I had one on a gen 3 Glock 34 years ago and liked the change in balance. But I have seen online reviews stating the GEN 4 has reliability issues with this upgrade, making it not much of an upgrade at all.

Does anyone have experience or insight to offer?

I've used SS guide rods in a few Glocks over the years, but always went back to the stock guide rods.
3 out of the 4 I tried had the allen screw come loose over time and I got tired of checking and tighten them..

IIRC the Gen 4 has a captive recoil spring unit. You can't replace just the guide rod. But I have heard of complete stainless replacement units.

Zero experience with the gen 4 weighted rods, but the one that came with my Gen 2 19 had the same problem. Allen screw kept coming loose. I finally loaded it up with clear nail polish and tightened it down. Hasn't moved in two years and a thousand or so rounds. I notice a bit quieter, smoother cycling during admin functions, and a teensy bit of drag on the slide cycle when shooting vs the stock RSA. Not better, just different.

Had a few with stainless guide rods in the gen 4s. They are salty (60 dollars a piece or so). Didn't notice much of a change in balance. It's a part I wouldn't bother with unless you're going for a lighter or stronger spring (playing with reloads at the range) and thats more with competition guns.

An ideal 19 for me is a set of night sights, trigger of your flavor (still want to play with an agency arms one to compare to my zev techs and haley ones I have now), and a vickers slide stop. Everything else is personal preference, but those three things I've done to all my 19s right off the bat. May need to get another 19 to try out that trigger since I'm thinking about it.

Depends on what kind you buy. Tungsten is brittle and is known to shatter.

If its a carry gun, I would stay with the stock setup. If its just a range gun, then I wouldnt care. I have a tungsten in my G34. I figure if it ever breaks, ill replace it. Its just a range gun.

Yes that is correct, but the units I'm finding for sale are all encompassing drop in replacements.

I didn't know that about tungsten, thanks! Yes this is for EDC.

Look up tungsten on Wikipedia and do a search on that page for brittle. I think there was 3 instances that it was mentioned on the page.

I just dont want to see it fail on you at the wrong time. Like I said, I have one on my G34, but its just a range gun. If it ever breaks on me, it will get replaced with a stainless rod.

And suddenly, 10mm.

I had an issue with my G23 where the slide stop wasn't popping back up properly. I took it in to Glock and the first thing they asked was if I had used a stainless guide rod. I had for a while, and the guy said that since the steel didn't give, it battered that part of the frame more deforming the polymer a little bit, enough to snag on the slide stop. He shaved a tiny bit down and I've stuck with the stock guide rod since then with zero issues.

That's exactly the kind of feedback i was hoping to find on sigforum; thanks!
