Performance Benefits You’ll Notice
Smoother Feeds, Fewer Stoppages
True-to-spec feed lips and a tuned spring help present each round at a consistent angle, promoting smooth chambering and reducing the risk of nose dives or bolt-over-base malfunctions when your pistol is properly maintained.
Positive Lock-Back
The follower geometry supports reliable slide lock on empty—vital for quick, predictable reloads during training or defensive use.
Durable Range Companion
The blued steel magazine body stands up to repeated drops on range surfaces, while the finish helps resist corrosion from sweat and the elements.
Ideal Use Cases
Everyday Carry (where legal): Keep a spare 17-round mag on your support side for immediate access.
Training & Classes: Rotate multiple magazines to keep drills moving and better simulate real-world reloads.
Home Defense Readiness: Stage dedicated, tested magazines so you can trust your loadout when it counts.
Competition Practice: Build consistent reload mechanics with mags that insert and drop just like OEM.
Care & Maintenance
Routine Cleaning: Wipe the exterior after range sessions; remove base plate to clean debris from the tube as needed.
Light Lubrication: Avoid over-oiling. A dry or very light film on contact points is usually plenty.
Inspect Wear Points: Check feed lips, follower travel, spring tension, and base plate fit—replace parts or the magazine if damage is observed.
Rotate Carry Mags: Periodically cycle between practice and carry magazines to maintain spring life and confidence.
Frequently Asked Questions
Q: Will this mag work in both Girsan MC28 and MC9?
A: Yes. Part 390117 is designed to fit both models. Always test function with your specific pistol and defensive ammunition.
Q: Is the magazine body steel or polymer?
A: Blued steel magazine body for durability and reliable feed-lip integrity.
Q: Do I need to “break in” the magazine?
A: Not usually. However, loading the magazine to full capacity and letting it sit, plus a few range cycles, can help the spring settle for optimal performance.

A: The follower is designed to engage the slide stop; proper lock-back depends on pistol condition, ammo, and correct seating.
Q: Are extended base plates available?
A: This listing includes the standard base. Some third-party accessories may fit; verify compatibility before modifying.
