Glock 19/23/32 Magazine Extension – +5 Round – Gen 1–5
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
This Cross Armory +5 Magazine Extension is built for compatible Glock 19, Glock 23, and Glock 32 Gen 1–5 magazines. It replaces the factory magazine base plate and adds five additional rounds to compatible Glock brand or Glock-clone magazine bodies.
The extension is CNC-machined from aircraft-grade aluminum and weighs about 1.35 ounces, keeping the profile slim, light, and usable without turning the bottom of the magazine into a boat anchor. Cross Armory designed it with aggressive grip cuts, an included upgraded feeding spring, and a compact shape that they state works with all magwells and holsters.
Capacity is great. Capacity that still feeds right is the part that keeps the range day from becoming a troubleshooting seminar.

Magazine Extension Fit Guide
| Magazine Body | Capacity Increase | Included Spring | Main Check |
|---|---|---|---|
| Glock 19 Gen 1–5 compatible magazine | +5 Round | Yes | Use only with compatible standard-capacity magazine bodies |
| Glock 23 Gen 1–5 compatible magazine | +5 Round | Yes | Verify magazine body and local capacity laws |
| Glock 32 Gen 1–5 compatible magazine | +5 Round | Yes | Function test after installation before serious use |
Note: Magazine extensions must be tested after installation. Capacity, spring tension, follower movement, magazine body condition, ammunition, and base pad installation can all affect feeding reliability.
What It Does
This extension replaces the factory magazine base plate and adds five rounds of capacity to compatible Glock 19, Glock 23, and Glock 32 magazines. The included upgraded spring is designed to support feeding from the first round through the last round after the extension is installed.
Why It’s Worth It
A good magazine extension should add capacity without becoming bulky, unreliable, or annoying to handle. This one keeps the profile tight, adds usable grip texture, and includes the spring needed to help the added capacity work properly.
The aggressive grip cuts are useful when stripping or handling magazines with wet hands, gloves, or dirty range conditions. Capacity without reliability is just decoration with consequences. Pretty decoration, maybe. Still consequences.
