Description
The P-11 is known for being compact and concealable, but that small frame can make it tough to get a full grip if you've got bigger hands or just want more control. This grip extension swaps out your flat magazine base plate for one that gives you room to get all your fingers around the pistol.
Designed as a magazine floor plate replacement, it works with factory Kel-Tec P-11 magazines and installs in minutes with no special tools. The rubber construction provides a secure feel, and because it stays on your mag, the grip is consistent every time you reload. Unlike some accessories that compromise concealability, this extension adds just enough length where you need it without making the gun significantly bulkier.
Real improvement in control and shooting
Once you install this on your mags, the difference shows up at the range pretty quickly. Having that extra purchase on the grip means better recoil management and steadier aim, especially during follow-up shots. The P-11 fires pretty snappy for a 9mm in its class, so better control translates directly to tighter groups and faster target reacquisition.
Installation and durability
Swapping out the base plates takes no time and requires nothing special. The rubber material holds up well and resists wear, and because it's a simple replacement part, it's just as easy to remove for maintenance or cleaning. This is an OEM Kel-Tec accessory, so it's built to the same standards as your gun.

Frequently Asked Questions
Does this P-11 grip extension add capacity to my magazines?
No. This extension only replaces the flat bottom magazine base plate with a longer one. It gives you more space to grip the pistol but doesn't hold any additional rounds.
How hard is it to install?
Installation is simple and tool-free. Just remove your current magazine floor plate and snap this one on. It takes a few minutes and requires no special knowledge or equipment.
Will this work on other Kel-Tec models?
This is designed specifically for factory P-11 magazines. It also works with the discontinued P40 model, but it won't fit other Kel-Tec platforms. Check compatibility before ordering if you have questions.
Does this make the P-11 less concealable?
The extension does add a little length to your magazine, but it's minimal and doesn't significantly affect concealability for most carry methods. You get noticeably better grip and control without dramatically changing the gun's profile.
