Centennial Defense Systems Trigger Assembly w/Stainless Steel Bar for Gen 1-4 Glock Review

First Impressions of Centennial Defense Systems Trigger Assembly w/Stainless Steel Bar for Gen 1-4 Glock

As a seasoned armorer and tactical gear enthusiast, I’ve always been on the lookout for ways to enhance the performance and reliability of my firearms. When I stumbled upon the Centennial Defense Systems Trigger Assembly w/Stainless Steel Bar for Gen 1-4 Glock, promising a smoother trigger pull and improved overall feel, I was intrigued. Could this be the upgrade my trusty Glock needed?

My search began when I noticed a slight grittiness in my Glock 19’s trigger. I’ve seen trigger upgrades promise the world, but often fall short. I was hoping this would be the exception.

The package arrived quickly, and upon unboxing, I immediately noted the clean, polished appearance of the stainless-steel trigger bar. Compared to the factory Glock trigger, the Centennial Defense Systems assembly looked like a significant step up in quality. The smooth finish of the metal inspired confidence.

I’ve tested similar trigger assemblies from Apex Tactical and Agency Arms. While those are excellent, they also come with a significantly higher price tag. The Centennial Defense Systems trigger assembly offered a potentially similar benefit at a fraction of the cost.

Initially, I was cautiously optimistic. The price point raised a few eyebrows, but the claims of a smoother trigger pull and drop-in installation piqued my interest. I was eager to see if it could live up to the hype or if it was just another budget upgrade that falls short.

Real-World Testing: Putting Centennial Defense Systems Trigger Assembly w/Stainless Steel Bar for Gen 1-4 Glock to the Test

First Use Experience

I installed the Centennial Defense Systems Trigger Assembly in my Gen 3 Glock 19, a firearm I frequently use at the range and in local shooting competitions. The installation was straightforward, truly a drop-in replacement as advertised. Immediately after installation, the trigger felt lighter and smoother during dry-fire practice.

My first range session with the upgraded trigger was a mix of drills focusing on speed and accuracy. I ran approximately 300 rounds, including a variety of 115-grain and 124-grain FMJ ammunition. The trigger felt noticeably improved, with less perceived creep and a cleaner break than the stock Glock trigger.

The weather was clear and dry, perfect for shooting, so I didn’t get to test it in adverse conditions during that initial outing. However, I did notice one slight issue: a couple of times, the trigger failed to reset after firing. This raised a concern about reliability under more stressful conditions.

Extended Use & Reliability

After the initial range trip, I continued using the Centennial Defense Systems Trigger Assembly in weekly range sessions and incorporated it into my carry rotation. Over several weeks, I put approximately 1000 rounds through the Glock with the upgraded trigger. While the trigger pull remained smoother than the original, the occasional failure to reset persisted.

I carefully inspected the trigger assembly for any signs of wear or damage but found none. Cleaning was easy. A quick wipe-down with gun cleaner and a light application of oil kept it running smoothly (when it reset properly, that is).

Compared to other aftermarket triggers I’ve used, like those from GlockTriggers.com, the Centennial Defense Systems assembly didn’t quite match their consistency and reliability. While the initial improvement was noticeable, the occasional reset issues made me hesitant to fully trust it in a self-defense situation. The unreliability outweighed the performance benefits.
