[ARCHIVED THREAD] - 17rd ETS mag causing trigger/sear reset issues?

Posted: 2/27/2020 5:44:01 PM EDT

so i bought a 17rd ETS mag to try out in my Gen 1 full size. it has apex trigger and sear. Many thousands of trouble free rounds. when i tried the ets mag, trigger/sear wouldnt reset about 50% of the time. swap to factory mag, no issues. same ammo. swap back to ets. same issue. how can a mag cause this?

Trigger bar is hitting the side of the mag. Is your trigger stock?

Apex. I check my stock trigger. No issues. Something with the change in geometry of the apex

Nice video. Well done. How much did you have to remove total approximately?

Thanks again for the video. I sanded mine down a couple nights ago. They seem to work now dry-firing. Who knows when I'll get to live fire them.
