yeah the kriss dont work with the supplied mag springs I TRIED. it's just too fat. If they have changed the width of the spring so it does not rub inside a 10mm mag body I'd like to see someone confirm this, maybe with a caliper measurement I can compare. did you also have to mod your follower? I would definitely go this route if it works now.
I do think that the magex could be made to work with a spring from a 9mm 33 rounder tho. you would have to add a block to the bottom of the inside of the mag but no biggie.
There was a gentleman on here who was doing all that chrono testing and had modified one for use in his carbine that worked well. I was hoping he would respond and share.
I have not done the legwork on this yet, but I bought two to experiment on. I suspect I may have to put a small cut in the supporting metal liner at the top rear so the feed lips can come together enough to hold the 10mm properly. I may just start with some hammering tho.
