What a Magazine Follower Does—and Why It Matters
Inside every magazine, the follower rides on top of the spring and pushes cartridges upward as the firearm cycles. It controls how rounds stack, how they present to the feed ramp, and how consistently the magazine keeps pressure on the next round. A properly functioning follower helps:
Present rounds at the correct angle for smooth feeding
Maintain consistent upward pressure throughout the stack
Support reliable last-round feeding
Ensure dependable slide lock on empty (where applicable)
Reduce the risk of malfunctions caused by worn or damaged magazine internals
Because the magazine is often the most common source of feeding issues in semi-automatic pistols, keeping the follower in good condition is one of the smartest maintenance steps you can take.
Specifically for Glock 43 Magazines
This follower is made for Glock 43 magazines, ensuring correct fit, proper geometry, and reliable travel inside the magazine body. Correct model compatibility is critical with magazine parts—followers are not universally interchangeable across Glock models. Using the correct follower helps ensure:
Smooth movement without binding
Correct cartridge presentation and feeding angle
Proper engagement for slide lock function
Reliable consistency from magazine to magazine
If you run the slimline Glock 43, keeping the right follower on hand is a practical, preparedness-minded choice.
Why Replace a Magazine Follower?
Followers don’t wear out as quickly as springs, but they can become damaged, worn, or contaminated over time—especially with heavy range use, dusty environments, or dropped magazines. Replacing the follower is a smart move when you notice:
Inconsistent feeding or nose-dives
Rough follower movement or sticking
Cracked, chipped, or heavily worn follower surfaces
Magazines that feel sluggish even after cleaning
Unreliable slide lock engagement
For many shooters, a follower replacement is part of a larger preventive maintenance routine—along with spring changes, thorough cleaning, and inspection.
Ideal for Maintenance, Repairs, and Spare Parts Kits
The Glock 43 follower #33390 is a great fit for:
Routine magazine refurbishment
Restoring older magazines that have seen heavy use
Keeping spares for training and range mags
Preventive maintenance for carry magazines
Armorers and builders who want essential small parts on hand
It’s also a smart “cheap insurance” item—especially if you rely on your Glock 43 for concealed carry.
Easy Upgrade During Magazine Cleaning
Many shooters clean their magazines periodically—especially after training in dusty, sandy, or wet conditions. Swapping a follower during cleaning is a practical way to refresh your mag internals with minimal effort. When maintaining magazines, it’s good practice to:
Inspect follower for cracks, gouges, or deformation
Check spring condition and tension
Clean debris from inside the mag tube
Confirm smooth follower travel after reassembly
Function check magazines at the range before relying on them for carry
A clean, smoothly traveling follower can make a noticeable difference in consistency.
