Centennial Defense Systems Extended Mag Release for Gen 4-5 Review

First Impressions of Centennial Defense Systems Extended Mag Release for Gen 4-5

The Centennial Defense Systems Extended Mag Release for Gen 4-5 promises faster and easier magazine changes for Glock pistols. As a firearms enthusiast with over a decade in tactical gear and outdoor equipment, I’m always looking for upgrades that improve functionality and efficiency. I was excited to get my hands on this relatively inexpensive part to see if it lived up to the hype.

My need for this product stemmed from a desire for quicker reloads during training scenarios. The factory Glock magazine release, while functional, felt small and required too much thumb manipulation, especially under stress or with gloves. I had previously used an extended mag release on a Gen 3 Glock and found it greatly improved my reload times.

Upon receiving the Centennial Defense Systems Extended Mag Release for Gen 4-5, I immediately noticed the clean machining of the 6061 aluminum. It felt robust and well-made, certainly a step up from the polymer factory release. Compared to similar offerings from Vickers Tactical and Agency Arms, the Centennial Defense Systems release stood out for its balance of price and seemingly good quality. While I’d used the Vickers Tactical release before and liked it, the Centennial Defense Systems offered a similar design at a significantly lower cost.

My first impression was cautiously optimistic. The quality seemed good, and the price was right, but the real test would be in the installation and use. I was hoping for a noticeable improvement in reload speed and ergonomics, but remained skeptical until I got it installed and tested at the range.

I tested the Centennial Defense Systems Extended Mag Release for Gen 4-5 primarily at my local outdoor shooting range. It was a sunny, mildly humid day, typical for late spring. I ran a series of drills focused on speed reloads using my Gen 4 Glock 19.

The immediate difference was noticeable. The larger surface area of the extended release made it significantly easier to depress the mag release button, even with gloves on. I found my magazine changes were smoother and faster, requiring less conscious effort. There were no issues related to the Centennial Defense Systems Extended Mag Release during the first range session.

Extended Use & Reliability

After several months of consistent use, the Centennial Defense Systems Extended Mag Release for Gen 4-5 has held up surprisingly well. There are no signs of significant wear and tear on the aluminum. I’ve fired approximately 1,000 rounds through my Glock 19 since installing it, and the magazine release has functioned flawlessly every time.

Maintenance has been minimal, mainly just wiping it down with a lightly oiled cloth during regular firearm cleaning. Compared to my previous experiences with polymer mag releases that sometimes felt flimsy, this Centennial Defense Systems release feels significantly more durable and reliable. It has definitely exceeded my expectations for a part in this price range.
