you know, I did that too when I attempted the mod, but now I'm wondering if I beveled far enough. I basically just knocked off the sharp edges left and right and did a solid bevel front and back. looking back at the followers and bodies I modded I noticed that one follower had not been beveled side to side only front and back. Maybe I need to go farther on the side bevels. I'm still stumped how you are getting that spring to fit without dragging in the 10mm body. Is it possible to measure yours?
