Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE Review

First Thoughts on the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE

The Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE is a seemingly simple, yet potentially crucial accessory for owners of the Kel-Tec P-11 who utilize S&W 59 series magazines. At a mere $7.49, it promises to enhance the grip and potentially the reliability of these magazines in the compact P-11 platform. But does it live up to that promise, or is it just another cheap add-on destined for the parts bin?

My journey to this extension began with a quest for increased capacity and improved grip on my Kel-Tec P-11. While the P-11 is famed for its concealability, the short grip can be a challenge for those with larger hands, and the factory magazine capacity leaves something to be desired. I was initially drawn to higher-capacity magazines from S&W that would function in the P-11, and this extension seemed like the perfect solution to blend capacity with grip comfort. I’ve always believed a good grip leads to better control and faster follow-up shots.

Upon receiving the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE, my initial impression was one of slight skepticism tempered with hope. The extension is small and lightweight. It’s molded from what appears to be a standard polymer. Compared to similar aftermarket extensions for other firearms, it felt almost too basic. I was immediately wary of its durability and fit.

I also considered purchasing complete aftermarket magazines with integrated extensions. However, these options were significantly more expensive. I also considered modifying existing P-11 magazines, but this involved more permanent alterations that I was hesitant to make. This extension offered a cheaper, less risky solution.

My first impression was a mix of curiosity and apprehension. I was hoping this small piece could significantly improve my P-11’s usability, but I was also prepared for the possibility of it being a flimsy, ill-fitting disappointment. It would need rigorous testing to prove its worth.

2. Real-World Testing: Putting **Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE** to the Test

   First Use Experience

   I first tested the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE at my local indoor shooting range. The range offered a controlled environment to assess the extension’s impact on grip and feeding reliability with various types of ammunition. I used a 15-round S&W 59 series magazine loaded with 115-grain FMJ rounds.

   The first few magazines fired flawlessly. I immediately noticed a significant improvement in my grip. The extension provided just enough added length to allow my pinky finger to comfortably wrap around the grip, resulting in a much more secure hold. This improvement translated directly to better recoil control and faster target re-acquisition. However, after about 50 rounds, I experienced a couple of failures to feed. I suspected the magazine wasn’t fully seating due to the extension.

   Extended Use & Reliability

   Over the next several weeks, I continued to use the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE during weekly range sessions. I also carried the P-11 with the modified magazine during several outdoor hiking trips, exposing it to varying weather conditions. This allowed me to assess its long-term durability and reliability in more challenging scenarios.

   After approximately 500 rounds, the extension showed no visible signs of wear and tear. The polymer remained intact, and the fit remained snug on the S&W magazine. However, the initial feeding issues persisted intermittently. I determined that the magazine could be slightly over-inserted, causing the slide to bind. I remedied this with a small amount of filing on the top of the extension, allowing the magazine to seat perfectly. After this modification, reliability drastically improved. The extension became a solid and reliable addition to my P-11 setup. This outstripped my expectations given the modest price.

3. Breaking Down the Features of **Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE**

   Specifications

   • Caliber: .40 S&W (Intended for use with P-11 chambered in .40 S&W when using S&W 59 series magazines). The product does not alter the caliber of the firearm.
   • Capacity: Designed for 15-round S&W 59 series magazines. It doesn’t increase the magazine capacity itself.
   • Finish: Black. A simple, utilitarian black polymer finish.
   • Model: Magazine Extension. This is solely an extension; it does not include a magazine.

   These specifications are crucial because they dictate the extension’s compatibility and intended use. The fact that it’s designed for specific S&W magazines is paramount; it won’t work with standard P-11 magazines. The black finish is purely aesthetic, but it blends seamlessly with most polymer frames.

   Performance & Functionality

   The primary function of the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE is to improve grip ergonomics when using S&W 59 series magazines in a Kel-Tec P-11. In this regard, it performs admirably. The added length provides a much more comfortable and secure grip, especially for those with larger hands.

   The extension’s weakness lies in its potential to cause feeding issues if not properly fitted. As my experience showed, slight modifications might be necessary to ensure flawless magazine seating. However, once properly fitted, the extension greatly enhances the usability of the P-11 with S&W magazines.

   Design & Ergonomics

   The design of the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE is simple and functional. The polymer feels reasonably durable, and the added length is well-proportioned to the P-11’s frame. The ergonomics are significantly improved compared to using the S&W magazine without the extension.

   There is a slight learning curve involved in ensuring the magazine is properly seated. Some may encounter issues if they aggressively slam the magazine into the well, which could lead to over-insertion and subsequent malfunctions.

   Durability & Maintenance

   The Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE appears to be reasonably durable for its intended purpose. The polymer construction should withstand regular use without significant wear and tear. Cleaning is simple; a quick wipe with a damp cloth is typically all that’s needed.

   Given its simple design, there is little that can go wrong with the extension itself. Its longevity depends primarily on the quality of the polymer and how well it interfaces with the magazine. I expect it to last for several years with proper care.

   Accessories and Customization Options

   The Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE itself doesn’t offer any specific customization options. It is a single-piece unit designed to fit a particular magazine. However, it indirectly opens up customization options by allowing the use of higher-capacity S&W 59 series magazines in the P-11.

   The extension is not compatible with standard P-11 magazines or any other magazine types besides S&W 59 series. This is a crucial consideration when purchasing.
