In the way-back days just prior to the AWB I bought two +2 magazine extensions for my Glock 21.
Good news! They will, indeed, allow you to insert 15 rounds into what was previously a 13 round magazine.
Bad news! As long as you don't mind that now only 11 rounds will feed before it jams, they're great!
They are effectively -2 extensions.
They behaved this way when I first got them, but I'd written it off to "old springs" since the springs in my magazines were a whopping two years old and had a couple of hundred rounds through them. So I took them off and tossed them in my big box o gun bits.
My brand new Glock brand magazines with 11 rounds through them have failed in this manner now. I should throw them away, but for some reason they're back in the box...
Edited to add a pic of the offending item. The thing it's sitting on is the latch base that goes between the spring and the base. It's got a post that sticks out the hole in the base.
