Quality high capacity mag for Glock 21?

[mike231]

I'm in the market for some high capacity mags for a Glock 21 so what do you guys suggest?

Might not be the cheapest option but look for Kriss Vector magazines or magazine extensions. The Vector uses Glock 21 mags and they came up with extensions for the standard magazines.

Do some research though I never actually found out if the extensions fit the Glock. The rep from Kriss told me they do when I was looking at their guns at the NRA convention.

These are the only ones I know of that I would call quality.I had them and they functioned flawlessly in my Glock 21sf and 30sf.
You can buy the complete magazine or the extensions to work with the Glock 21 13 round magazines.
I know there are some Japanese 27 round mags available but I have never tried or would try them.

I found one at a local dealer in lancaster pa for $29.99 and bought it. Went to another dealer today in New Holland and they were sold out. If you find any please post here. I found some decent Glock 19 mags but cant seem to find the 21's.
