The Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE Made a Bold First Impression

The Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE is a seemingly simple piece, but it holds the promise of improved grip and capacity for your Kel-Tec P-11. This little extension, manufactured by Kel-Tec, is designed to work specifically with 15-round Smith & Wesson magazines, transforming them into compatible accessories for the P-11. I was hoping this would solve some capacity issues I have with my P-11 when using it for concealed carry.

My journey to this product began with a persistent search for increased magazine capacity for my Kel-Tec P-11. The standard 10-round magazine felt insufficient, especially during training exercises and scenarios where a higher round count provides peace of mind. I’d been experimenting with S&W 59 series magazines, knowing they could be adapted, and this extension seemed like the perfect way to finalize the conversion.

Upon receiving the extension, I was immediately struck by its compact size and what appeared to be solid construction. The CNC machining looked clean, and the polymer felt durable enough for the task. It was a simple black piece, and I held high hopes that I wouldn’t have to fumble with grip.

Compared to some generic magazine extensions I’ve used in the past, the Kel-Tec part seemed more robust and purpose-built. I considered some other, less expensive extensions but ultimately chose this one for the Kel-Tec name and the promise of a precise fit. My first impression was cautiously optimistic. I was eager to see how it would perform in action, but a little skeptical about compatibility.

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

First Use Experience

My initial testing ground for the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE was my local shooting range. I wanted to evaluate its reliability and impact on the P-11’s handling. I loaded up a 15-round S&W magazine with 115-grain FMJ rounds and inserted it into my P-11 with the extension properly installed.

The range environment was fairly typical with moderate temperatures and dry conditions. The Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE was relatively simple to install on the S&W magazine, requiring only a few minutes and no specialized tools. Initially, getting the magazine seated was a bit tight, but that broke in.

During the first few magazines, I experienced a few failures to feed. This was a bit disheartening, and the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE certainly didn’t seem to improve this. I suspected the issue stemmed from the magazine spring or the angle at which the rounds were being presented to the chamber, but that ended up not being the case.

Extended Use & Reliability

After several range sessions and approximately 300 rounds fired, the Kel-Tec CNC P11 MAG EXTENSTION FOR S&W 15RD MAGAZINE showed no signs of physical wear or cracking. The polymer construction seemed capable of withstanding the repeated stress of magazine insertion and removal. I continued to experience the failures to feed with different brands of ammo, eventually coming to the conclusion this was the magazine itself, and not the extension.

Cleaning and maintenance were straightforward; I simply wiped it down with a cloth after each use. No special solvents or lubricants were necessary.

While the extension itself held up well, the initial feeding issues highlighted a potential limitation. Compared to the factory 10-round magazines, the modified 15-round magazines were noticeably less reliable in my particular P-11. The extension was not the issue, but using a modified magazine inherently is going to introduce more potential failure points.

The main strength is its simplicity and potential for added grip length. However, the dependence on a specific type of magazine, and the issues I personally experienced, could make it not as useful as it would seem on the surface.
