Search for “KCI”, “Khan” or sometimes called “Kahn” at your favorite gun catalogs. They are South Korean made to spec of the Glock mags and should sell for around $13.99 which is what I paid for mine but my seller is sold out.
Sportsman’s Guide has them but are way over priced even if you join their “club” for the discount.

What the fudge is Tom teaching folks to rack the slide with their britches?
I don’t think I’ll be doing that...
Well, the 31 rounder I bought when I purchased the rifle is a KCI and it will feed only thirtee rounds before jamming, with a bullet pointed nose down. I’m gonna take it apart and file out the roughness I can see when I have the bottom off. The plastic and metal has a piece of what looks like the black plastic obstructing the mag tube at one of the holes. I have never had a true Glock mag that would not feed properly after loading it up to one less than specs and leaving it for a couple of days. This KCI hi cap wouldn’t allow more than thirteen rounds into it before tipping nose down.
