shooterDrew - I'll change the followers and see what happens - Thanks! STIboy - Right length = 1.160 (+ or -), I have tuned the mags, including the sandpaper thing. Thanks for your thoughts.

STI 9mm magazines (126mm), loading 11 rounds for IDPA. Mags feed well most of the time, but occasionally there will be an instance where the cartridges do not move readily upwards, as though the spring has lost tension. It does not happen consistently and it has happened in each of the STI magazines that I use. Bullets are the right length, the springs are new and the mag is clean. I switched to a stronger spring and the problem still shows up every now and then. Any thoughts or suggestions?
