Thanks for the vid. I was able to get the .560 on the body and the right feed lip dimensions, but then the mag doesn't drop as smoothly as before and the follower doesn't fit all the way through to the top, so the gun no longer slide locks (not that I want it to but I'm tuning a slide lock mag). So I tap the body with the hammer like you do in this video, enough to the point where the mag now drops freely and the follower fits again, but now the body is in the .580 range and the front feed lip around .370. I can't seem to adjust one without messing up the other, no matter how many times I go back and forth.

Do you have similar measurements for STI gen 1 magazines to share? Would be much appreciated.

Awesome video, thank you creating this content. I am looking for those pliers now but a link in your videos would be nice.

Hey agw. How many magazines were ruined until you were able to be consistently good at retuning mags?

I have three 6 month old sti mags and one inch down I’m getting.690, .685, and .713 is it supposed to be that far out on a mag tube that’s never been tuned?
