Shield Arms 5/ 4 magazine extension for Glock 17/22/19X.
Great product so far, Easy install, perfect fit. I want to add that for the Glock 19X installation you must remove  the safety cord attachment for the magazine to fit and seat correctly. Perfect fit on my Glock 17C.

Shileld arms for glock 22 .40
Happy with it so far,came a day early and works great at the range, a little wiggle room by the back set screw, but still works great. Definitely buying more for glock 22.

Amazing quality and craftsmanship!
Awesome quality, added  5 to my EDC Glock 17, and functions flawlessy at the range. Already 1000 rounds put through them and 0 malfunction. The extra power spring really does add some extra spring tension (beware) and the cut out grooves in the mag extensions make them easy to pull out of mag pouches!

One of the best.
Fantastic machining quality, nice weight, and easiest mag ext to install.
Ordered and received in 4 days. I own a couple mag ext from various vendors and this is my favorite. Definitely will be purchasing more.

5/ 4 extension
Magazine extensions are all the same, right? Wrong, these are easily one of the most user friendly extensions I've used. The only issues you could have with these is user related (I'm dumb and stripped a set screw). Customer service is top tier for sure, sent a message and was squared away immediately. There are a lot of companies who claim the best, but Shield Arms puts their money where their mouth is. It also helps that there are people in the firearms world who put products to the test and vouche for them (Aaron Cowan, see Sage Dynamics). I will now be a life long customer.
