Looks like you need to get rid of one. I’ll help with the 17L.

If you buy factory OEM it will be close to the same price. There are decent aftermarket slides and parts available that reduce the price and make it more economical. A friend of mine only owns 2 glocks a 17 and a 19 but he has full slides for .40 for both and .357 sig so it's like owning 6. I have several myself and a few i've built. One in 22TCM9R and am considering getting a 460 Rowland kit for my G21. the 460 has similar ballistics to a 44 mag..the conversion is about $1200 but it's hard to beat 22000 pounds of energy at the muzzle

The Lone Wolf conversion barrels are fine.
I tell anyone who will list to stay away from their Alphawolf barrels. I've had tons of problems with them. I don't think the conversion comes in Alphawolf, but if you stumble across one, I would skip on by it. Their standard LW barrels are fine though.

That’s a 34C, Glock made 2 Glock 35C’s which I passed on to a close friend to buy. I made a Glock 35C to mirror them as well as the above.
Picked up a Lone Wolf threaded Conversion barrel for $100 and a g19 gen 4 spring for $20 as LWD suggests. Put ~100 rounds of 9MM through a g23 gen 4 without issue. Barrel shot better than me.
For $120 + mags, it seems like a decent solution for the range at least.

For what this is worth: IMHO, if you want to swap calibers on a Glock that you own (for models that share a common frame), the best way to go is to buy an entirely new OEM slide/barrel assembly and mags, not just the barrel and mags. I'm comfortable with the idea running different caliber slide/barrels on the same lower (unless it's Gen 2, because of the single- vs. two-pin difference), but not multiple barrels in the same slide. I'm especially skeptical of the idea of going from 9mm to any larger caliber, or just calibers that have more muzzle energy and put more wear-and-tear on the guns.
I've debated purchasing a Gen 3 G22 slide/barrel to run on my Gen 3 G34 frame, just so that I can have a .40-cal gun if there's ever a big shortage of 9mm again. I like the fact that I can find those slide/barrel assemblies new (or almost new) for $300 on GunBroker and eBay. I see the argument that it's better to just buy a whole new pistol, since Gen 3 Glocks are so inexpensive, but I'd rather get a new slide barrel so that I don't have to wait for another 77R (since I'm in MD).

I can only add on the conversion unit concept. Can’t say how many I built on 1911’s. I have two, and those slide/barrel assemblies will most likely find homes elsewhere. When I want to shoot 9mm I grab a 9mm pistol.
Be it any convertible capable pistol to make a conversion it must be built as that caliber to run correctly - like the mention of an ejector needing changed in one Glock conversion. By the time the conversion is completed costs are minimally separated by cost of an additional pistol. Then there is the hassle to convert. Not bad if changing top ends and mags, but it would be difficult change out at a match where switching calibers between stages could be annoying…and problemstic. Even some Contender guys at sihlouette matches squawk when the whole match is shot in stages, for each division and class.
With Glock clones abounding which improve on the Glock ergonomics a whole pistol may be a practical option. Or maybe a different brand model pistol all together.

The .40 to 9mm barrel is pretty thick and slightly changes the balance of the pistol if you are starting with a .40. Some like that.
The weight difference between the stock .357 sig barrel and the conversion barrel should be negligible if any though.

Total necro quote, but this guy on eBay is selling what I am 99% sure are Bar Sto conversion barrels. As stated previously, .40 to .357 Sig conversions (and vice versa) are a 10 second barrel swap. Other than markings, they are otherwise identical.
Also worth noting, factory G31 barrels are not sold to the public and are as good as gold in the used market.

I think this makes the most sense, if you can find the slide/barrel assembly at an attractive price.
I would like to have a G17 upper to swap onto my G22.
I ordered a G31 barrel directly from Glock. I did have to call customer service and provide the serial number of my G22.

No another collector on GlockTalk. It’s too much of a unicorn not to share.

Very nice, I have some Gen1 shooters. Some are safe queens.

Is this kosher? A civilian shooting a departmental (assumption) weapon?

And that can definitely be a challenge sometimes. I see a lot of sellers who will ask for slide/barrel assemblies for $350+ (and sometimes more), depending on the Glock model. At that point, I do think it makes sense to just buy another gun. But if you can get them for under $300 (which is definitely possible), then it seems like the best way to go about doing a conversion (IMHO).
Side note: I've also considered buying a Glock 17L slide/barrel to run on my Glock 34 frame. I've always liked that model and wanted one, but it's impossible to find the slide/barrel assemblies for under $650 right now. That's definitely an example where it makes more sense to buy a whole new gun.

This is true. When P80 got popular, tons of used Glocks were being broken down and sold for parts, the frames close to free. When Marylandistan passed the 80% law, I realized it was easier and cheaper for me to buy a stripped frame for $40 (FFL employee, free transfers) than to go through the hassle of getting a P80 frame engraved and registered.
