Description
The Ghost Inc. Magazine Extension Device for the Glock 43 solves what a lot of owners deal with right away: the slim, compact design that makes this gun ideal for carry also means you're starting with just six rounds. This extension bumps your capacity up to eight rounds per magazine while keeping the same low-profile footprint you want for concealed carry.
How the Ghost Extension Works
This kit reuses your factory base plate, which keeps things simple and means there's no permanent modification to your magazines. The polymer body slides onto the bottom of your magazine and locks in place securely. Inside, you get a heavier-duty stainless steel spring that's built to handle the extra pressure from loading two additional rounds. The pinky rest design gives you extra grip real estate, which is one of the benefits people notice right away when they run it.
Install and Reliability
Installation takes minutes and doesn't require gunsmithing. You'll need to separate your magazine base plate using the spreader tabs or vise grips, slide the extension on, and you're done. The best part is reversibility if you ever want to go back to stock configuration. Since it uses the factory base plate, you can remove the extension cleanly without damaging the replacement spring they include.
Customers who've run hundreds of rounds through these extensions report reliable feeding from the first round to the last. The spring tension is engineered specifically for the Glock 43 magazine tube, and Ghost backs everything with an unconditional lifetime warranty.

Frequently Asked Questions
Will this extension work with newer generation Glock 43 magazines?
Yes, this extension is designed to work with OEM Glock 43 magazines. Glock did make some updates to magazine internals over the years, but the Ghost extension accommodates both older and newer magazine versions. If you have any compatibility concerns, Ghost Inc. provides excellent customer support.
Can I remove this extension later without damaging my magazine?
Absolutely. Since the extension reuses your factory base plate, you can remove it cleanly by sliding it off the magazine body. The included spring can be removed through the base plate, so you won't get it trapped like you would with some other designs. Your magazine returns to stock configuration.
How much longer does the magazine get with this extension?
The extension adds minimal length to your magazine while giving you that valuable pinky rest. The added length is modest enough that most people find it doesn't hurt their carry setup, especially for those with larger hands who benefit from the improved grip.
Does this come with a replacement spring?
Yes. The kit includes a stainless steel spring rated for the additional two rounds. The heavier spring maintains proper feeding pressure throughout the mag's capacity, which is why this extension performs so reliably compared to options that skip the spring upgrade.
