    Good buuuuut...

    Posted by Michael on 27th Jun 2025

    I love the feel, the pistol is a micro comp so it feels small but with this extension it really fill out my hand, my only gripe is that its not a 2 pack, the prices are 3d printed and totally could be sold as a pair. My gx4 came with 2 mags it would make this a 5 star if this were sold like a pair. I was thinking it was but I realize now the picture in the description shows the 2 types of extensions. Lakeline: Good point! We will look to add.

    This product gave me a quick and value-priced way to convert a 10 round GX4 magazine to a 15 rounder. NOTE: you will need to put a small bend in the tip of the spring to allow it to fit in the slot of the magazine follower (check the spring that you are replacing to determine the length of the bend).

    Overall the design is awesome, however the screw it came with doesn’t necessarily fit the extension pieces properly. Which caused it to lift near the hole. Unless that’s how it’s supposed to be?.. Either way it’s a great addition for GX4.

    I thought I was getting an actual 15-round magazine. LakelineLLC: it is CLEAR in the description. You are welcome to return for a refund.
