Kriss Super V extensions do not work with G20 mags.
Another guy on a different forum also described the problem with the supplied spring and other problems and presented workarounds he devised to make it work (January, 2010).
10mm fans.... Finally a 33 round mag that WORKS!!
Interesting! Either 1) the Kriss people reshaped the spring enough to work with both 45 and 10, 2) I got lucky straight out of the box with MY mag, or 3) the original problems were flukes. Get your bets down!
