I doubt this review will help anyone else, but I wanted to pass along how this mag worked for me when others would not. I built a one of a kind pistol, a Taurus PT24/7 Pro in 10mm. It was the 45 ACP version, and with some fairly minor work, I was able to convert the 40 caliber slide/barrel to 10mm. The problem I ran into using the OEM 45 ACP mag or even a Mec-Gar P14 mag was fail to feed, especially with JHP ammo.
Doing some research, I found the Armscor 40 cal mag was supposed to work for 10mm for a similar pistol. The price here was better than anywhere else- when you could find one- so I ordered a couple. I was pleasantly surprised how my first mag of 16 JHP rounds fed perfectly. Service here was great, shipping was fast and reasonable. I would definitely buy from Greg Cote LLC again.
