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.

These springs fixed the issue i had from adding the +2 round bases on my Glock 21. Before these i had inconsistant feeding and jams. These springs cured that issue 100%, they cost less than Wolff springs and shipped 10 times quicker.

I'm a competitive shooter. I rebuild my mags every year. This year I've been running my Glock 21 and when I went to order piwer springs it didn't seem that anyone had them. So I ordered these and I'm glad I did. They are well built and should be great for the upcoming year. I'll definitely buy them again.
