NOT UNLESS YOU HAVE A MILLING MACHINE

by William W., Verified Owner from TN, United States Written on March 21, 2026
These bound-up in the left handle extractor slot in my reprise Gen 1 Glock 17L. I was going to send them back, but could not readily find any with the reduced power spring. Soooo, after checking dimension with my $400 Mitutoyo (spelling?) micrometer, I found that the offender was the raised flat on the inside by the striated thumb release. Using a 1/2 inch end mill, I removed a few thousands of an inch and it fit fine.

AT THIS PRICE?

by William W., Verified Owner from TN, United States Written on March 16, 2026
After struggling to get the magazine release out of my Glock special re-run of Gen 1 9mm Long Slides, this overpriced POS is too big to slide in the hole at the left side of the handle. Not only “NOT RECOMMEND” but DO NOT EVEN THINK OF WASTING YOUR MONEY!
Pros:
  • None
Cons:
  • does not fit
Best Used for:
  • Garbage
  • Garbage Can

Centennial Mag Release

by Steve, Verified Owner from NH, United States Written on May 1, 2025
Does not fit the Glock 21SF. The round inside radius causes the magazine not to go all the way in. They need to fix this.

Good Product!

by Dale, Verified Owner from FL, United States Written on September 19, 2024
I like it! Especially for the PSA Dagger. I've bought other extended mag releases only to find they stick out too far and fit loosely in the frame. This one seems much better and secure. I can pull pretty hard on the mag. and it won't come out. Yet to use it under live fire. I'll modify the review if the mag falls out. So far so good.
