I’ve been using 17/21 rd magpuls for about 80% of my range work since they became available. Not a single issue with them in any of my Glocks. Although I go hate the 12 bc it pinches.

Glock has offered the +2 extension for the G26 since it was introduced.

They also make a +5 extension.
I have put a good number of rounds through their G17 mags. They’re harder to load full than a G mag which means they’re putting more resistance on the slide. I’d never carry one for that reason alone. I wish I’d spent the extra bux for OeM, for the 16th and 17th round and the witness holes.

I hope the Magpul mags work because I have 5 on the way. From Midway, they cost $10 each instead of $25 each for OEM magazines. I figure I can have 5 magazines to use and abuse in training and in local matches and keep from putting that wear and tear on OEM mags. We’ll see how it works out.

I have had good luck with brass cased round nose out of the Magpul mags. They didn't do well with steel, aluminum, or HST.
I have 2 21s, 12 15s, and 11 17s. I got 'em all new for less than $8/mag or I wouldn't have any.
Beater mags.
Weird. I've only shot aluminum and maybe some steel through mine. Federal aluminum and maybe Winchester Forged.
I've got Magpul mags for my G26, G19, & G17/34 guns.
G26 Magpul mags are 12 rounders and work fine and I'll use them for carry. I also bought the Glock-brand extensions which are +2 in 9mm, but I put them on my G27 mags which are +1 in .40.
G19. These were OK, until I also got a G19Gen5. For some reason (I can only suspect slightly different geometry with the new Gen5 slide-stop) I'll get an intermitttent premature slide lock-back when there's still one round left in the mag. These mags don't always feed well with steel-cased ammo (which many don't use anyway), but neither do stock Glock mags.
G17. I haven't yet noticed if there are any premature slide lock-back problems with my one Magpul 17 round Glock mag in my G17Gen5 and I haven't used this 17 round Magpul mag in my G19Gen5. These mags also don't feed steel-cased ammo as well as the stock Glock mags but the Glock mags aren't 100% either with steel cased ammo. If you only shoot brass-cased ammo then no worries. Due to my steel-cased ammo use, I did put stock Glock mag springs into a few of my Magpul 17 round mags which slightly helped.
Overall, I see no issues using Magpul Glock mags for carry in my Gen3 and Gen4 Glocks, but they're not approved by me for my G19Gen5. So far, I haven't had any problems with my 17 round Magpul mags in my G17Gen5, but I haven't really dedicated a few hundred rounds through just my Magpul 17 rounders to thoroughly feel confident with them other than in my Gen3 & Gen4 Glocks.
I haven't been trying the 15 and 17 rounders in the smaller Glocks; i.e. I use the 12 rounders in my G26 guns; the 15 rounders in my G19 guns; and the 17 rounders in my G17&34 guns.

The g26 Magpul extension may is awesome. It works really well.
Glock extensions have known issues with breaking.

I ran the 21s in USPSA this season, no issues at all with AE 147s in thousands of rounds through a 34 G4 MOS. They run after being dropped in the sand (much to the annoyance of Open shooters) and come apart quickly if needed for brushing out.
I have less experience with the 17 rounders but no issues there either.
