STOP!!!!
If you have a Glock 30 gen 5 and plan on using Glock 21 oem mags you need this upgrade!!. I find the spring pressure inadequate to feed the short slide of the g30 you will get FTF and double feed issues with oem springs. I will be leaving a video review on this product on YouTube soon as I get my Glock store blue slushy. This store saved my Glock ??

G21 extra power mag spring
I run .40 Super through my G21. It has a high slide travel rate, and factory springs aren't strong enough for reliable feeding. These dropped right in, increased the feed pressure and solved the issue.

Ensures feeding with .45 super
I bought these because .45 Super will operate the slide a little bit faster than regular magazine springs are designed for. I bought three springs to try out, and they work as advertised. One note; these springs are for a newer revision of Gen 3 magazines- I had one where the spring hooked in directly to the follower, whereas the AGP springs are designed to slip fit around the follower's base.

Great replacement springs, I felt the difference while loading/unloading the magazine.

Magazine Springs
I put plus 2’s on my Glock 41 magazines. The OEM spring still worked but lost a good amount is resistance. Ordered the Glock 21 extra power springs. They’ve been flawless. Definitely gonna order more for spares. Plus my order was completed and shipped in less than 24 hours. Awesome job.
