The Henning Group Magazine Extension Kit for Glock 17/34/19X/45 increases magazine capacity from 17 to 23 rounds! Our design has been thoroughly tested and used extensively by Law Enforcement and Competitive Shooters. The design of our extension is a true extension of the internal shape of the factory magazine tube. Combined with a stainless steel, 13-coil magazine spring it is a proven and reliable solution. Our Glock 17/34/19X/45 magazine extension is CNC machined from 6061-T6 billett aluminum. Fit to magazine body is tight and secured using a black nitride finished cap screw.   The Henning Group Plus 6 magazine extension can installed on any Glock G17 or G34 magazines, including the 31/33 round magazines. 

We have two options for springs:

A. Henning Group 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 the factory spring.
