Most Helpful Positive Review Awesome product
Easy to use and works with the zev pro magwell. Definitely buying another.full aluminum nice and ergonomical compared to other mag extensions ive used. Easy fast reloads and not to expensive being zev products related.
Most Helpful Negative Review Not worth the money
Disappointed to say the least. Well machined and looked great. The big flaw here is the locking tab that runs vertically in the back to hold the bottom plate. It is held in position by a rubber "nub" in the channel, but not enough upward pressure to secure this critical piece in place, resulted in...

feels amazing

by notenough, Verified Owner from MI, United States Written on October 23, 2020
Once you hold this it feels very durable and awesome. Has a bit weight to it but the material on this is a1. I wish zev made more for different handguns besides glocks. Will be buying some more pretty soon!

Repeat Purchase

by DMarq, from TX, United States Written on August 16, 2020
I’ve added these to every g17 and g35 magazine I own. They look and feel clean and sturdy. They stay on even when dropped hundreds of times. Careful not to lose the little spring when installing. A little pricey, but you get what you pay for.
Pros:
  • Lightweight
  • Sturdy
  • Clean & Streamlined.
Cons:
  • A little pricey
Best Used for:
  • uspsa
  • recreation shooting

+5 Horsepower!

by Mr.Styler, from CO, United States Written on July 12, 2020
One of the best mag extensions I’ve used thus far! Super easy installation and easy to remove, unlike some other brands, if you want to put them from an old mag to a new one. Looks awesome to boot, and the spring is nice and strong. Can’t go wrong if you’re trying to get a little more Bang for your buck. (Only works on Glock oem mags.)
Pros:
  • Added capacity
Cons:
  • None

Zev mag extensions

by Abrown, from TX, United States Written on April 18, 2020
Still have not received my items. I ordered them on 3/18/2020 and I was able to buy the same thing from another company. Still waiting. The product is great but would like what I ordered from you. Can you please contact me ASAP to let me know when I should expect to have my items.

Solid base plate

by Chris, from VA, United States Written on October 15, 2019
Great quality, usual Zev fit and finish. Just be careful you are ordering for the right type of mag. Mistook the Glock vs Magpul compatible Glock magazine and ended up with the wrong type. One is not interchangable with the other so double check before you buy.

Terrible springs

by Chuck, from FL, United States Written on June 24, 2019
Do no buy!!! I was sent bad springs which after firing 2/3 rounds, the spring becomes decompressed and you just have loose rounds inside of your magazine. I purchased 4 mags and 3 of them had this issue. I am returning these immediately!

Doesn’t work well with Glock 40 cal

by Brian, from KY, United States Written on October 17, 2018
I bought these to be drop in. With Gen 4 Glock Magazine, I had to file the followers down tremendously to get them to work. I only did so much work because I really liked the look of the Zev extensionsz
