First Impressions of JL Billet 9/40 Glock Single Stack Magazine Extension
The JL Billet 9/40 Glock Single Stack Magazine Extension promises to enhance the capacity and handling of your Glock magazines. This aircraft aluminum extension, manufactured by JL Billet, claims to add +1 or +2 rounds for 9mm and .40 S&W respectively. With its hard anodized finish and focus on drop-free reliability, it aims to bridge the gap between aesthetics and functional performance for Glock owners.
As a seasoned firearms enthusiast, I constantly seek improvements to my gear. I was drawn to the JL Billet extension because I needed a reliable way to increase the capacity of my Glock 19 magazine without sacrificing its concealability. Many extensions add bulk, but the promise of a minimal profile with added functionality piqued my interest.
Upon unboxing, the JL Billet 9/40 Glock Single Stack Magazine Extension felt solid and well-machined. The orange anodized finish (the color I opted for) was vibrant and evenly applied, suggesting a quality coating. The weight, a reported 1.3 oz, felt substantial, adding confidence that it would indeed promote drop-free operation as JL Billet claimed.
Compared to a standard Glock magazine baseplate and a similar extension from a competitor (Strike Industries +5 extension), the JL Billet felt more robust, less “plasticky.” While the Strike Industries offered higher capacity, it also significantly extended the magazine length, impacting concealability. The JL Billet seemed to strike a better balance.
My initial reaction was positive and hopeful. The build quality appeared top-notch. I was eager to test its performance and reliability on the range.
Real-World Testing: Putting JL Billet 9/40 Glock Single Stack Magazine Extension to the Test
First Use Experience
I first tested the JL Billet 9/40 Glock Single Stack Magazine Extension at my local shooting range. I installed it on a Glock 19 magazine and used both 9mm and .40 S&W rounds. The weather was dry and sunny, offering optimal conditions.
The installation was straightforward, replacing the factory baseplate with ease. During live fire, the magazine fed reliably, and the added weight seemed to assist in smooth magazine ejections. I experienced no malfunctions directly attributed to the extension, such as failures to feed or double feeds.
There were no significant surprises, and the extension performed as advertised during the initial range session.
Extended Use & Reliability
After several months of consistent use, the JL Billet 9/40 Glock Single Stack Magazine Extension has proven its durability. It’s been subjected to various range conditions, including hot summer days and slightly damp environments. The finish has held up well.
There are no signs of significant wear and tear. The anodized coating remains intact, resisting scratches and fading. I cleaned the extension after each range visit using standard gun cleaning solvents and a brush.
Compared to cheaper, polymer extensions I’ve used in the past, the JL Billet offering significantly outperforms them in terms of longevity and reliability. The aluminum construction and robust finish make a tangible difference.
