Most Helpful Positive Review Works Perfect
0 failures so far. The trick is to break in the follower spring by loading them and letting them sit. Once the spring is adequately broken in, I had 0 failure to feeds and 0 failure to extracts. All the issues you see are only seen fresh out of the box. These mags work perfectly fine. I could unders...

Most Helpful Negative Review Causing numerous FTF malfunctions
I should have researched this mag more thoroughly before buying it. It's causing multiple failure to feed issues repeatedly. Apparently they work for some people, but it seems most they dont work. Not worth risking these not working when really needed, ill just stick with oem mags.

Shield Arms S15 Gen 3 Glock 48/43X

by Steve, Verified Owner from NH, United States Written on October 28, 2025
Excellent magazine. Bought these for my other 43X so I had to purchase them for my second 43X! Works very well. Probably as good if not better than the OEM mags.

Must have for the 43X

by Sam B., Verified Owner from IL, United States Written on September 30, 2025
I was worried about reliability, but this is amazing. It is extremely durable and cycles 15 rounds like a champ. Sometimes the last few rounds are hard to get in the magazine, but they go every time.
Pros:
  • Durability
  • reliability
Cons:
  • Stiff
Best Used for:
  • Self defense
Would recommend: Yes

No issues.

Despite what some say, you CAN use the factory mag release-- HOWEVER the metal mags will eat up the platic release rather quickly, so its best to replace the magazine release with the shild arms metal release right away.
The starter kit with three mags and a release replacement is a good deal. I rrally liked the g48 alot but strongly disliked the 10 round capacity. This puts you to 15 with options to extend to 20.
Super easy to replace the release. Took 5 minutes, most of that fiddling around.

Make you 48 worth carrying. Get these.
Pros:
  • EASY INSTALL
  • capacity
Cons:
  • None
Best Used for:
  • EDC
  • Personal Defense
Would recommend: Yes

What's better than 10rds. . .15rds!

by Aaron, Verified Owner from NM, United States Written on September 17, 2025
If you decide to get these mags, you'll have to install the mag-catch to go with them. Afterwards, the original Glock mags won't come loose easily, but it's still worth it if you buy 3+ of these for personal carry & range practice.
