Description

The Kel-Tec P-11 magazine extension is a simple, effective way to get more from your standard 15-round magazine. This polymer basepad adds one extra round while significantly improving how the gun feels in your hand. It's one of those small additions that makes a noticeable difference if you've got larger hands or find the P-11 a bit snappy to control.

What This Extension Does

Instead of the thin, tapered factory basepad, you get a fuller grip platform that extends the magazine slightly. Your pinky no longer hangs off the bottom of the grip, which means better contact with the gun and more control. The textured black finish gives you something to grip without being abrasive. Installation takes no tools and only a few minutes, since it simply replaces the factory base plate.

Build and Materials

Kel-Tec made this from durable polymer that stands up to regular carry and use. The fit is tight and clean against the magazine body, no wobble or rattle. The extension is designed specifically for the factory 15-round P-11 magazines, so compatibility is straightforward. Unlike some aftermarket parts that need tweaking to fit right, this one works as-is.

Real-World Application

This works well whether you're putting rounds downrange at the range or carrying for personal defense. Having that extra round in the magazine, plus a better grip platform, gives you a slight edge without adding bulk or changing how the gun carries. Users with smaller hands might find they don't need it, but anyone who struggles with getting a solid grip on the P-11 will see why this is worth the investment.

Frequently Asked Questions

Will this extension fit all P-11 magazines?

This extension is designed specifically for factory P-11 15-round magazines. It replaces the original basepad on those 15rd magazines. Other magazine capacities use different basepads, so check your magazine capacity before ordering. If you're unsure, measure your magazine or contact us with your serial number.

Do I need tools to install the P-11 magazine extension?

No tools required. This is a straightforward swap that takes a couple minutes. You simply remove the factory basepad from your 15-round magazine and slide the extension into place. If you've ever changed a basepad before, you already know the process.

Does the extension really add usable capacity?

It adds one round to your magazine, so a 15-round magazine becomes a 16-round magazine. The bigger benefit for most users is the improved grip platform, which lets you get a fuller hand on the gun. That translates to better control and less hand fatigue during longer range sessions.

Will my P-11 magazines fit in the gun with this extension installed?

The extension is designed to work with the P-11 and sits flush against the grip when inserted. You'll still get a clean fit in your holster and magazine pouches. Some users with certain holsters or tight carry setups may want to test fit first, but generally it works without any issues.
