Genuine Glock OEM – Factory Fit & Reliability
As a factory replacement part, the 3206 floor plate is made by Glock to the same standards as the original parts that ship on new pistols:
Manufactured to Glock’s exact dimensions and tolerances
Uses the same materials and production methods as original magazine floor plates
Designed to provide excellent fit, secure retention, and reliable operation
If you’re rebuilding a carry or duty mag, sticking with OEM Glock parts helps ensure you don’t introduce weak links into your system.
Durable Black Polymer Construction
The Glock Magazine Floor Plate 3206 is made from tough, impact-resistant black polymer:
Withstands drops, hard use, and repeated reloads
Resistant to common cleaners, oils, and lubricants
Maintains a factory-correct look that matches Glock magazines and frames
If your original base plate is cracked, dented, or chewed up from training and range work, this is the correct part to restore your mags to like-new condition.
Made for Square-Notch, Metal-Lined Magazines
This floor plate is specifically designed for Glock’s newer-style, square-notch magazines:
Fits square-notch, metal-lined magazine bodies
Works on Gen3 and Gen4 magazines and is compatible with many Gen1–Gen4 pistols in supported calibers
Commonly recommended as a replacement for factory mags that match this pattern
If you’re updating older mags or mixing parts, ensure your magazine is the square-notch FML (full metal lined) style to guarantee proper fit.
Simple, Tool-Light Installation
Swapping a damaged base plate for the Glock 3206 floor plate is quick and straightforward:
Ensure the magazine is unloaded.
Depress the locking plate tab via the hole in the floor plate.
Slide the old floorplate forward off the mag body while controlling the spring.
Transfer the locking plate and spring, if needed, and slide the new floor plate into place until it locks securely.
Most users can perform the change with just a small punch or similar tool; no gunsmithing is required.

The Glock Magazine Floor Plate 3206 is a smart addition to any serious shooter’s parts supply:
Replace cracked or dented floor plates from hard training or duty use.
