The Shield Arms Magazine Release for the Glock 43 (part no. G43-EMR-BLK) is a steel-faced mag catch optimized to work with the Shield Arms Z9 magazine, the extended 9-round mag that turned the G43 into a genuinely usable carry gun. Shield Arms machines it from aluminum and finishes it in anodized black to match a factory-finished slide and frame. It stays compatible with the factory plastic OEM magazine too, though Shield Arms recommends pairing steel-on-steel or plastic-on-plastic to minimize wear over time. This is a direct-fit upgrade for anyone running Z9 magazines in a G43 or G43X-pattern pistol.
