Kriss MAG-EX2 magazine springs have no tension.
I’ve been experiencing major feeding issues using these mags (9mm) with my Vector and other Glock magazine compatible PCC’s and pistols.
I’ve noticed that once the magazine gets to about 15 rounds, there is almost zero tension left in the spring. The follower/rounds can be almost effortlessly pushed down, causing the next round to not raise fast enough for the bolt to catch it and chamber it.
I pulled my mags apart today (I have 6) and all but one had zero tension once the bottom plate is unlatched.
I know replacing the springs is the correct fix, but for now I stretched them back out. I’ll replace them during the next Kriss site wide sale.
Just showing here what they should look like versus being completely collapsed.
Middle picture is showing a stretched spring on the right and an existing collapsed spring on the left with the bottom plate unlatched.
I leave these mags fully loaded in the safe, as I believed that “using a spring, compressing and uncompressing, weakens it, not storing it under tension”. I no longer believe this, and probably will leave all but one unloaded from now on.
