Glock doesn't make one.
Of the aftermarket ones, the Arredondo +5 is supposed to be good, but pricy.
For +2, from what I've read, the Sherer is the only one worth buying.
I ordered a few, I'll check them out when they get here.

I got one of the 2-packs I ordered today, of the Scherer "Super 2" extensions.
It's a two piece design like the factory Glock baseplates, both the base and the locking liner are plastic.
The locking plate is too short, so it was a pain in the ass to actually get it positioned right.

Once I got it on, I was only able to load 15 rounds (using the standard Glock spring and follower). After loading and unloading a few times I got 16 in, and eventually was able to get 17, but the feedlips were bulging pretty bad so I just stayed with 16.

Thinking about loading it up with 17 and leaving it inserted in the gun overnight (so the pressure is taken off the feedlips) but I'm not sure how good of an idea that is. Also kinda worried that it will deform the mag catch relief/slot in the magazine.
I don't really want to fuck up a good mag with the way prices are right now

Thanks for the feedback.  I assume you're trying the Scherer's on a G20, hence the 17rd capacity?  That's not especially encouraging though.  If you could barely fit +2 in 10mm, it seems lke +2 in .45 would be next to impossible.

It's a 2 round extension. 13+2=15. Why would you try forcing 17 rounds into it??
