Premium Steel Construction for Your Glock 43
When you're carrying concealed, every component of your Glock 43 needs to perform flawlessly. The Standard Z-Series Mag Catch replaces your factory plastic magazine release with a precision-machined steel component that's engineered to work seamlessly with Shield Arms' high-capacity Z8 and Z9 magazines. While the factory Glock 43 magazine catch is made from polymer, the increased capacity and steel construction of Shield Arms magazines benefits from the superior wear resistance that only a steel-on-steel interface can provide.
This magazine catch features an ambidextrous design that works equally well for left or right-handed shooters, with a chamfered, textured button that provides positive tactile feedback during magazine changes. The low-profile design maintains the slim profile essential for concealed carry while offering improved ergonomics over the factory component. Available in multiple premium finish options including DLC (Diamond-Like Coating), the Z-Series Mag Catch is built to withstand thousands of magazine changes while maintaining consistent performance.
Manufactured entirely in the USA from premium steel and backed by Shield Arms' 100% lifetime warranty, this magazine catch represents a significant upgrade for any Glock 43 owner, particularly those running Shield Arms magazines. The steel construction ensures longevity and reliability, while the precision manufacturing tolerances guarantee proper function with both Shield Arms and OEM magazines.

Important Compatibility Notes
Material Pairing Recommendation: For optimal longevity and performance, Shield Arms recommends pairing materials appropriately. The steel Z-Series Mag Catch is ideal for use with steel Shield Arms Z8 and Z9 magazines, providing a steel-on-steel interface that minimizes wear on both components. While this mag catch is compatible with factory plastic Glock magazines, prolonged use may result in increased wear on the softer plastic magazine material. For extended use with OEM magazines, consider the plastic magazine catch option, or plan for eventual magazine replacement as normal wear occurs.

Finish Options Explained
DLC (Diamond-Like Coating): This premium finish offers exceptional wear and abrasion resistance with high lubricity that reduces friction during operation. DLC is chemically non-reactive and provides superior protection against corrosion while maintaining a sleek, professional appearance.
Peacock Blue: An iridescent PVD coating that displays multiple colors with blue as the dominant shade. Due to the nature of PVD coating processes, slight color variations may occur between individual units, making each piece subtly unique.
PVD Coating Process: All color options utilize Physical Vapor Deposition (PVD) coating applied over the steel base material. This industrial coating process provides excellent durability and corrosion resistance. Minor fixture marks may be visible on the interior surfaces but will not be visible once installed in your pistol.
Frequently Asked Questions
Will this mag catch work with my factory Glock 43 magazines?
Yes, the Z-Series Mag Catch is fully compatible with OEM Glock 43 magazines. However, since the mag catch is made from steel and factory magazines use polymer, extended use may result in increased wear on the plastic magazine material. For optimal longevity when using OEM magazines long-term, consider pairing plastic with plastic (factory mag catch with factory magazines) or upgrading to Shield Arms Z8 or Z9 steel magazines for the best steel-on-steel pairing.
What's the difference between the Standard and Premium Z-Series Mag Catch?
Both versions are made from precision-machined steel and share the same core functionality. The Premium Z-Series Mag Catch features enhanced machining, additional texturing options, and premium finish choices. The Standard version offers excellent performance at a more accessible price point while maintaining the same durability and reliability Shield Arms is known for.
Is special installation required, or can I install this myself?
The Z-Series Mag Catch is designed as a drop-in replacement for the factory Glock 43 magazine catch. Most Glock owners with basic familiarity with their firearm can complete the installation with simple hand tools. Detailed instructions are included with your purchase. For visual guidance and additional tips, visit our installation guides page for comprehensive tutorials.
Do I need to buy anything else to use this mag catch?
The Z-Series Mag Catch works as a standalone upgrade with your existing Glock 43 and magazines. However, to maximize the benefits of the steel construction and get increased capacity, we recommend pairing it with Shield Arms Z9 magazines (9 rounds) or Z8 magazines (8 rounds). For an optimal complete setup, check out the Z9 Starter Kit which includes a Z9 magazine and mag catch together.
Will this mag catch cause accelerated wear on my magazines?
When paired with Shield Arms steel magazines (Z8 or Z9), you'll have an ideal steel-on-steel interface that provides maximum durability for both components. When used with polymer OEM magazines, the harder steel mag catch may accelerate wear on the softer plastic magazine material over thousands of magazine changes. This is normal physics of material interaction and doesn't indicate a defect—it's simply the nature of steel against plastic.
Are there any legal restrictions on installing an aftermarket mag catch?
Magazine catches are generally not restricted components in most jurisdictions. However, firearm laws vary significantly by location. It is your responsibility to understand and comply with all federal, state, and local laws regarding firearm modifications in your area. When in doubt, consult with a qualified firearms attorney or local law enforcement.
What does the lifetime warranty cover?
Shield Arms backs the Z-Series Mag Catch with a 100% lifetime warranty covering defects in materials and workmanship. If your mag catch fails due to a manufacturing defect, Shield Arms will repair or replace it at no charge. The warranty does not cover normal wear, abuse, unauthorized modifications, or cosmetic changes. Shield Arms stands behind their products because they're manufactured in the USA to exacting quality standards.
Can I use this with magazine extensions like the Z9 +3?
Absolutely! The Z-Series Mag Catch works perfectly with magazine extensions including the Z9 +3 Mag Extension. In fact, when you're running higher capacity with extensions, the improved ergonomics and reliability of the steel mag catch become even more valuable. The magazine catch interfaces with the magazine body itself, not the extension, so all Shield Arms extensions are fully compatible.
How does the low-profile design benefit concealed carry?
The low-profile button design reduces the risk of accidentally dropping your magazine during concealed carry while still providing positive tactile feedback when you intentionally activate it. The chamfered edges prevent snagging on clothing during the draw, and the reduced profile maintains the slim characteristics that make the Glock 43 ideal for concealment. You get improved ergonomics without sacrificing the compact dimensions crucial for CCW.
Will the color of my mag catch wear off over time?
The PVD coating process creates an extremely durable finish that bonds at a molecular level with the steel substrate. While no finish is completely immune to wear, PVD coatings are among the most durable available for firearm components. The DLC option offers the highest wear resistance. Any wear that does occur will typically be limited to high-contact areas and will take extensive use to become noticeable. The steel underneath ensures continued functionality regardless of finish wear.
Is the ambidextrous design truly equal for both hands?
Yes, the Z-Series Mag Catch features a truly ambidextrous design with symmetrical button geometry that works equally well regardless of your shooting hand preference. Left-handed shooters will find the same positive engagement and ergonomics as right-handed shooters. This is particularly valuable for instructors, rental guns, or shooters who train with both hands.
