If you look at my thread - you can see that not every 115gr ammo may cycle gen5 g34. My slide with leupold red dot is 558g. I am waiting for a set of replacement rsa springs to test it.Second question first; the G17L slide was ALREADY engineered to be lighter, by adding internal cuts to remove "excess" steel at various points (see pics below). This got the slide weight down to within 10 percent of a stock G17 slide (17L slide was still about 1.5 ounces heavier). Although not highlighted in red, also note the deep/dark oval cut at the right-center of the G17L slide photo.

I don't think there is any more excess weight that can be trimmed from a G17L slide without potentially affecting long-term durability (the photos are of older Glocks, so perhaps the slide cuts or configurations have been changed over the years).
Perhaps someone with a Gen3 G17L could check their slide and see if the cuts are still there, and still similar to these early-model cuts?
To your first question: I have not yet checked to see if the G34 slide has the same internal lightening cuts as a G17L. If not, then adding them in the Gen5 G34 could (at least partially?) make up for it not having a window cut.

They also made the G17L in Gen1 and Gen2 versions.I think all G17L are Gen 3 but i am not sure. Mine is a Gen 3 and has a cut out slide but no ported barrel.
I just checked a Gen 3 17, 34, and 17L side by side.Perhaps someone with a Gen3 G17L could check their slide and see if the cuts are still there, and still similar to these early-model cuts?
But they don't have the oval cut. There are some circular pattern machining marks (from a mill?) but no recessed area. Even on your pic, is that an actual cut that would catch a pick or fingernail, or just a machining mark?Although not highlighted in red, also note the deep/dark oval cut at the right-center of the G17L slide photo.
We're all the Gen 1 and Gen 2 guns ported? I have seen the ported 17L but I don't know when Glock did away with the porting. They were having problems in the porting area of the barrel. The ported ones are hard to come by now.They also made the G17L in Gen1 and Gen2 versions.
The photos I posted are of my Gen1, which is why I thought there might have been later changes.

I do not recall any of the 17Ls being ported. But with the slide cut, it is so easy to just drop in a ported barrelWe're all the Gen 1 and Gen 2 guns ported?

Nice photo!Mine is a Gen3 non ported but with the slide cut out. Here is the ported model View attachment 856868
Only a small percentage of the Gen1 17L models were ported, but due to the way the cuts were made, the barrels had a tendency to crack between the port slots. When people started to send the cracked barrels in for replacement, Glock (apparently) decided to cut their losses and replace them with solid/non-ported barrels (which probably wasn't a really popular decision with the owners, I'm guessing). No other Generations of G17L models had any factory porting (that I am aware of; I've recently been told otherwise), so the ones that survived intact are fairly uncommon (dare I say "rare"?).I do not recall any of the 17Ls being ported.

I think what I am calling the oval cut, you are calling the channel cut.But they don't have the oval cut. There are some circular pattern machining marks (from a mill?) but no recessed area. Even on your pic, is that an actual cut that would catch a pick or fingernail, or just a machining mark?

If you find a factory-ported Gen1 G17L in decent condition with all the original accessories, examples have been selling for several thousand dollars or more to collectors. Mine is a "shooter grade" (no accessories other than a few mags), but I bought a non-ported factory barrel so I can still shoot it occasionally without stressing or possibly cracking the original ported barrel.

Got a link to a source for that? I'm always open to learning.There were Gen 2 17L's that were also ported.

Not saying someone couldn't put one together, but I'm pretty sure the slotted ported barrel had been discontinued before the Gen2 models were released, so I'm wondering how that could happen.
Interesting! That's the same 4-port porting style they used on the G24.Better than a link, I am lucky enough to have one. All numbers match.
My son shot my 17L so I no longer have oneI used to own a 17L and foolishly sold it. This was several years ago. I’m really wanting to replace the gun. They are available through online sales but I might wait until I see one in a shop or gun show. This will be a house/range gun.
Please share your thoughts and experiences regarding the 17L.

Any chance you could post a view of the box label?
If you don't want to show the serial number, you could block that out (manually or digitally).
* sigh * -- Another one I need to watch for at the gunshows and pawn shops...

Sad when you have a “purpose “ to buy a gun you like.Wow, you'd think the OP is not allowed to own a 17L.
In all seriousness, if you want another one buy one.
