Glock 17/22 Double-Stack Magazines – Aluminum Magazine Extension – +5 9mm / +4 .40 – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Strike Industries Aluminum Extended Magazine Plate for Glock-pattern double-stack magazines is the tougher, heavier-duty version of their EMP line. It is machined from 6061-T6 aluminum, uses an aluminum locking plate, and is built for shooters who want extra capacity without the cheap, bulky brick look.
This version is black and is built for compatible OEM Glock 17 and Glock 22 pattern magazines. It adds +5 rounds for 9mm magazines and +4 rounds for .40 S&W magazines.
Fitment
- Fits Glock factory OEM double-stack magazines for Glock 17, 17L, 19X, 22, 24, 34, 35, and 45.
- Works with 9mm and .40 S&W magazine bodies in that fit family.
- Compatible with the SI EMP Pocket Clip.
- Tested by Strike Industries to work with the SI Magwell.
Does NOT Fit
- Does not fit 10-round magazines.
- Does not fit ETS magazines.
- Does not fit every Glock magazine automatically.
- Not for single-stack Glock magazines or unrelated magazine families.
What It Does
This extension increases magazine capacity while giving you a low-drag, no-snag profile that still looks clean on the gun. It also adds weight at the bottom of the mag for more confident reloads.
Why It’s Worth It
The aluminum EMP is the more premium route over the polymer version if you want harder-use construction, sharper fit and finish, and a more planted feel during reloads. It is still a small part, but it does a serious job at the bottom of the magazine.

Install Notes
This aluminum EMP is intentionally designed as a tight-fit system. Strike specifically warns against overtightening the set screw, and notes installation should be done carefully because the fit can damage polymer magazine base ears if handled badly. This is not the part for caveman install work.
Verify Before You Buy
Verify you are using compatible OEM Glock double-stack magazines in the G17/G22 family and not a 10-round or ETS magazine before ordering. After installation, test magazine lockup, feeding, slide lock, and drop-free behavior before relying on the setup.
