3 of 5 Good mags, bad ejection January 25, 2021
Reviewer: Ben from Texas  
The magazines are great. Seam to be durable and hardy. However I'm having an issue with the ejection. With the magazine empty, there's no issues, when loaded they won't eject at all. Nothing gets hung, just feels like the magizine is a tad too thick.

3 of 5 Needs a little work January 23, 2021
Reviewer: Sig Fan from NH  
Bought a few of these because the price is right.  Friend he uses them in his Glocks told me they work well.  However, when I went to use them, my slides kept locking back with 1 round left.  Tried multiple magazines, both 15 round and 17 round mags, tried them in both my P320C and my AXG full size frame.   Same results for 6 out of the 7 magazines I tried.  Upon further examination, I discovered that the little tab on the follower is just a little too tall.  It sticks out just above the edge of the magazine when there is one round left and pushes the slide catch up.  I was able to use a razor blade to cut off a tiny bit of this tab and now they work fine.  If they could just fix this tiny issue, I think they would be great.

4 of 5 1st look January 11, 2021
Reviewer: DangerousOath from FL, USA  
Wanted to give a couple of these a shot because I didn't feel like taking out a second mortgage for OEM Sig mags. Haven't got it to the range yet, but loaded up smooth. Love that you can get an idea of round count with just a glance instead of trying to find the witness hole on the factory mags. I'll update after I get to the range but got an excellent feeling about 'em.
