JagerWerks +5 Magazine Extension with Spring for Glock 17/34/45/19X Magazines.


Machined in house from 6061 Aluminum, black (Type III) Hardcoat Anodized.

12 Coil Spring for +5 Magazine Extensions included. 

Our new +5 Magazine Extensions use ramped retention posts and require no tools to secure. For removal you just need a small flathead or a prying tool to get the rear wall of the magazine over the posts while applying pressure to slide the magazine out.


We will not ship these magazine extensions to California, New York, New Jersey, Connecticut, Massachusetts. Illinois, Rhode Island, Hawaii, or Washington.

    Bought this for my gen 5 17 as it is running a Jagerwerks milled slide and I wanted to finish it off with this extension. I replaced the OEM glock +2 with this one, which is a pretty similar install. To my surprise this +5 is just barely bigger than the OEM +2. I will be purchasing a few more soon!

    Install was as easy as it gets, as is disassembly. Through ~250 rounds with the extension equipped mag, including drops for reloading, I've had flawless functioning. Solid product
