Which Glock has the reputation as 'most' reliable?

I don't think BTF is a reliability issue either, annoying but reliability is if the gun cycles or not.

BTF is erratic ejection which can cause a reliability issue.

2008 models and before.
 
So, which Glocks are unreliable in stock form? I honestly dont know of any. All of my gen-3's like like a top.
My first 2002-era G22 was quite a drama queen, even with no light on the rail. This was when Glock was still denying there was a problem. A local Glock armorer told me the stop-gap fix was heavier magazine springs, which I installed. Problem solved. Soon afterward, I heard that Glock had, quietly, started installing heavier magazine springs in their G22 magazines.

I later learned that one of my G22 pistols would regularly lock the slide to the rear, with ammo in the mag, using 180-grain ammo. (I had used only 165-grain, up to that point.) This was due to a defective slide latch, which was engaging the nose of the 180-grain bullets. (I am not sure what the official Glock term is, for that part.)

There were plenty of word-of-mouth stories going around, among LEOs, regarding problems with the .40 Glocks. My case was not isolated.

I have also seen the bulletins disseminated among police agencies, regarding problematic Glocks. One I recall, specifically, involved the Glock G21. A quite large PD in California had pulled all G21 duty pistols from service. I do not recall the exact problem, but long-time G21 fans may remember.

On the original topic, the G17 has been the benchmark of reliability, for as long as I have been paying attention, until some recent issues in both the Gen3 and Gen4, but those problems seem to have largely been resolved by this point. I reckon I would feel quite at peace with any G17, up to an early Gen3. Of course, it would be a case of trust, but VERIFY! Glocks may not need "breaking in," but function-testing is always important.

The early G21's with ambi-mag release (not early G21's), probably the first round of the SF models, had problems with that mag release. I seem to remember the mag release assembly's were crumbling to pieces.
 
I had a Gen 2 G17, until the slide cracked, at which point I graduated to a Gen 3 G17, which as been just has reliable as the Gen 2.

I also carry a G26 daily and shoot a G21, G20 and G29. I can't see that any of them is more reliable than the others.

Gen3 G22 had feeding problems when weapon lights were attached

Can someone elaborate on this?

I had seriously considered picking up a trade-in Gen 3 Glock 22, but definitely will not if I can't count on it to be reliable. Is there a simple, cheap fix for this unreliability with a light attached?

I thought Glocks were supposed to be uber-reliable, but if not, I will stick with my Walther P99 for HD (which currently sports a light and has never had a single failure in many many thousands of rounds.)

adding weight to the front introduced too much flex in the frame.

Simple? sure. cheap? I guess that depends. 500 bucks or so will put you in a Gen 4. Which was the fix, BTW... Previous gens were 9mm ported to 40. Gen4's were designed around 40 then ported to 9mm. Course now 9mm seems to be their problem child.
 
Thanks for the explanation. Maybe I should be looking into a more reliable pistol design.

A real shame though - one store here has loads of police trade-in gen 2 and 3 G22s for $300 and $350.
 
It was explained to me as the exact opposite.

When a WML is attached tightly to the rail it stiffens the dustcover, which doesn't allow it to flex enough...less that the designed spec. This reduced degree of flex shortens the dwell time of the returning slide and causes feeding problems. That is why Glock's band-aid "fix" was stronger magazine springs...to raise the cartridge column faster.

It is true that pre-Gen4 mid-frame Glocks are more reliable in 9mm than .40
 
I owned a Glock 19 that was a pitiful gun. Factory could not fix it, nor could two local gunsmiths. As a Glock that jammed, failed to eject, but mainly stovetopped, it was a true collectors item.

I swapped it & $180 for a Model 34 at a gunshow, and have had zero issues with the 34.
 
send the slide back to glock if you have it for replacement

How do you think I got that new slide? :p I didn't send it in, though, I took it by in person. Glad I dropped it by, as I wound up getting a brand-new Gen 3 Glock for $43, with the exception of the fact that we kept my old barrel.

How do you know if the magazine springs are the newer version?

I just received a replacement Gen4 19 from Glock a week or two ago, due to failure to extract.

The replacement runs good.

Their QC is definitely in the crapper though. (spent shells are 9mm)

Dont matter in my state. Just hope the person who ends up with the G22 dont live in a Nazi one.
 
I've never really been a Glock guy. However through the years I've always heard about the G26 being a very reliable 9mm Glock that many Glock owners carried. One day A friend of mine asked if I wanted to buy his Gen 3 G26 with only ten rounds through it for $350. After looking at the pistol one could call it previously owned as opposed to being called used. The one mag never had rounds in it.
So I bought it off him, figuring I'd use it as trade bait some time in the future.
The problem is it slowly won me over and now it would take a very fine deal to get it off me. So I'm going to have to agree with those who say it's the G26. I have shot the 17 and 19 and there good guns for sure but still the only glock I'll ever own is the G26,because if I'm going to a duty size pistol I'm going to CZ 75's not glock. (which I have already done with no regrets)
 
Did you mean to explode? :what: I'd have to say any of the .40 S&W models.

I know, right? That's why no departments or agencies use them anymore! They're all time bombs, waiting to bring fiery deaths to all who use them! Not that kabooms actually matter. Everybody knows Glock grips are so blocky and uncomfortable to hold that people die just from holding them!

This definetly made my day with your qoute RBid!

Im gotta go with the Glock 17/19 for the OP's question.
 
Never had a bad one, 9mm 45 and 40, several of each over 25 years.
 
Our office has 60 G-19's. Several others carry sub compact Glocks, two of us (myself included) carry G-34's. Some folks are gun folks, most are so-so, a few are not gun savvy in the least.

I can not recall one misfire, breakage, or other problem over the past 10 years we've had these guns issued.
 
The most common answers that I've seen in this type of discussion are the Gen 2 & 3 17s and 19s.

Having said that, it appears that the following have also generally been ultra reliable. When no Gen is specified, I'm noting that they appear to have been great across all Gens.

- Glock 23, Gen 2 & 4
- Glock 21 Gen 4
- Glock 29
- Glock 20
- Glock 27
- Glock 26
- Glock 32
- Glock 33
- Glock 24
- Glock 35
- Glock 22 Gen 2 & 4

I suppose it would be better to say, "everything except 9mm Glocks from late Gen 3/early Gen 4 and .40 S&W Glocks from Gen 3 with lights attached".

In my own personal experience, I have had zero failures with Glocks that I have owned or fired, to include:

Glock 23 Gen 3 (never fired with a light on it)
Glock 23 Gen 4
Glock 19 Gen 4 (my own plus multiple samples)
Glock 19 Gen 3 (multiple samples)
Glock 19 Gen 2 (2 samples)
Glock 21 Gen 3
Glock 21 Gen 4
Glock 30 SF
Glock 26
Glock 22 Gen 3
Glock 22 Gen 4
Glock 24
 
If you have enough money to buy enough ammo to wear out a 17 you have way more money than me. Mine is a gen 3 RTF and is trouble free as of now at 20,000 + rounds. I still prefer my 1911s but I can't kill this plastic marvel.
