Genuine Glock OEM Magazine Catch – Built for the Slimline 9mm
This is a Glock factory magazine catch, not an aftermarket clone. That means:
Direct OEM replacement for the original mag catch in your Glock 43 Slim 9mm
Designed specifically for the slim single-stack frame geometry, not double-stack models
Manufactured to Glock’s strict tolerances for perfect fit and reliable function
Using genuine OEM parts is the easiest way to keep your Glock’s performance and reliability exactly as the engineers intended.
Reversible Design – Perfect for Left- or Right-Handed Shooters
The reversible design of the Glock 33369 magazine catch lets you configure your Glock 43 Slim for:
By swapping the catch and repositioning it, you can:
Make reloads faster and more natural for lefties
Set up the pistol for weak-hand-only training or specialty use
Provide true ambidextrous-friendly capability across multiple shooters
This is particularly valuable for households or agencies where both left- and right-handed shooters may use the same pistol platform.
Secure Magazine Retention with Smooth, Positive Release
A quality mag catch must balance secure retention and easy release, and this OEM Glock part does exactly that:
Strong, precise engagement with the magazine notch keeps your mag locked in place during recoil, movement, and carry
Properly shaped release face allows your thumb to drop magazines cleanly without needing excessive pressure
Designed to work with Glock 43 Slim 9mm magazines for reliable, repeatable function
If your current catch is worn, chipped, or feels inconsistent, replacing it with a factory Glock 33369 is a simple way to cure intermittent mag seating or drop issues.
Perfect for Carry, Duty, and Defensive Pistols
The Glock 43 Slim is one of the most popular concealed carry pistols on the market, and your magazine catch is a critical control on that life-saving tool:
Ensures your magazine stays locked in when you need it most
Enables fast, instinctive magazine changes under stress
Maintains OEM-level reliability for serious defensive applications
Because of its importance, many shooters prefer to stick with a Glock OEM catch rather than experimenting with oversized or aggressively modified aftermarket versions on a dedicated carry gun.
Ideal for Maintenance, Upgrades, and Custom Builds
The GLOCK OEM Magazine Catch Reversible 33369 is a smart addition to:
Routine maintenance on a heavily-used Glock 43 Slim
Parts upgrades when converting to a more lefty-friendly configuration
Custom builds where you want all core controls to be OEM-spec
Armorer’s kits for departments, instructors, or serious Glock owners
It’s a small, inexpensive part that can have a major impact on your gun’s usability and reliability.
Durable Polymer Construction – Glock Tough
As with many Glock frame components, the 33369 magazine catch is made from high-strength polymer:
Lightweight and robust, matching the texture and color of the factory frame
Resistant to corrosion, moisture, and common gun-cleaning solvents
Designed to hold up to years of daily carry, training, and hard use
This keeps your magazine catch tough enough for real-world duty while staying comfortable against the hand and clothing.
Easy Installation with Basic Glock Armorer Skills
Installing or reversing the magazine catch is a straightforward process for anyone familiar with Glock internals:
Unload and field strip the pistol, double-checking that it’s clear.
Use a Glock tool or punch to carefully manipulate the mag catch spring.
Slide out the original catch and insert the new OEM reversible catch 33369 in the desired orientation.
Re-seat the spring and function-check magazine insertion and release.
If you’re not comfortable with detail work on your frame, a qualified gunsmith or certified Glock armorer can perform the swap in just a few minutes.
