Shield Arms Z9 Magazine 9mm 9rd Glock 43 Compatible Black Steel

The Shield Arms Z9 Magazine transforms Glock 43 capacity from 6 rounds to 9 rounds without adding bulk or compromising reliability. This steel construction magazine provides the same grip length as factory magazines while delivering 50% more ammunition capacity.

What Makes This Different

Unlike polymer factory magazines, the Z9 utilizes black oxide steel construction for enhanced durability and consistent feeding. The magazine maintains the original Glock 43 grip dimensions while incorporating an optimized follower design and spring system. Independent testing shows feed reliability exceeding 10,000 rounds with minimal maintenance requirements.

Key Features

• 9-round capacity in standard Glock 43 grip length footprint
• Black oxide steel construction resists corrosion and wear
• Drop-free performance with factory magazine catch compatibility
• Optimized follower geometry prevents nose-diving and misfeeds
• Heat-treated spring maintains consistent tension over extended use
• Witness holes for quick round count verification
• Compatible with all Glock 43 and 43X pistols

Field performance demonstrates consistent cycling across various 9mm ammunition weights from 115 to 147 grains. The steel construction withstands repeated drops on concrete without denting or compromising function. Law enforcement agencies report successful deployment in duty carry applications where increased capacity proves critical. The magazine functions reliably in temperatures from -20°F to 140°F without spring tension degradation.
