Glock 17 – Magazine Base Extension – +5 Capacity – Black
PLEASE DOUBLE CHECK DETAILS, FITMENT, AND LOCAL MAGAZINE LAWS BEFORE PURCHASE.
The Odin Works PMB for Glock 17 full-size 9mm magazines adds 5 rounds while giving the shooter a weighted, ergonomic base for faster mag changes and easier stripping. It is CNC machined from 6061 billet aluminum, hard anodized, and comes with an extra power spring plus Odin’s threaded pin system.
This is a capacity-changing magazine base extension, so fitment and local laws both matter. Verify your exact magazine body before ordering. Magazine extensions are useful. Wrong-fit extensions are just tiny metal regrets.
Fitment
- Fits Glock 17 full-size 9mm magazines.
- Capacity Increase: +5 rounds.
- USPSA 140 mm gauge compliant per manufacturer.
Does NOT Fit
- Do not assume Glock 19 compatibility.
- Do not assume universal fit across every Glock-pattern magazine without checking first.
- Does not make restricted-capacity magazines legal where local laws prohibit them.
What It Does
This extends magazine capacity and adds weight and grip surface for faster reload work. The extra power spring helps support the added capacity, while the threaded pin hardware keeps the base extension secured when installed properly.
Why It’s Worth It
This is a strong option for competition or range shooters wanting more rounds and a more useful basepad than a plain factory floorplate. The aluminum body, added weight, and ergonomic shape make reloads cleaner without turning the setup into a bulky mess.
