BLEM/AS-IS/WHILE SUPPLIES LAST
Sold as extension only and there are no color options - you will get what we have while supplies last. If you have a few color preferences, you can write that in your comment and we will accommodate if possible. It is a great opportunity to get functional extensions that have varying degree of discolored finish, scratches or otherwise not in perfect visual condition. We do guarantee that they work and function as promised. 

The Henning Group Magazine Extension for Glock 17/34/19X/45 increases magazine capacity from 17 to 23 rounds! Combined with our stainless steel, 13-coil competition spring it is a proven and reliable solution.

We have two options for springs:

A. Henning Group 13 Coil Competition Spring (using factory follower). If installed on a 17 round mag, you need to include our extended magazine spring to ensure proper function. If installed on a 31/33 round factory magazine, use your factory spring.

B. MBX Follower and Spring increases capacity from 17 to 24 + 1. No Lock Back! Only for 17 round mags.


For USPSA competition shooters, this extended base pads is legal for USPSA Limited, Limited 10, Limited Optics, Carry Optics and Open competitions as well as 3-Gun. Attached to the factory Glock magazine, they extend the magazine to 141.25mm length (5.56"). Whether you want to be competitive or not, these pads will extend the capacity of your Glock 17/34 magazines. 

Again, note:
- Extends the capacity on factory 9mm Glock 17/34 magazines from 17 rounds to 23 rounds. (extended spring needed)
- Extends the capacity of factory 9mm Glock 31 round and 33 round magazines to 37 rounds (use with factory spring)
