The Glock 21 Magazine is an essential accessory for Glock .45 ACP pistols, designed to provide reliable feeding and durability in various outdoor and sporting conditions. This magazine is engineered with a hybrid construction, combining robust materials for enhanced performance.

Key Features:

• Hybrid Construction: Features a stiff metal tube encased in Glock's proprietary high-tech polymer. This design prevents the magazine from deforming, even when dropped or exposed to extreme temperatures, ensuring consistent function during hunting or sporting activities.
• Double-Stack Design: Despite the large .45 ACP calibre, the staggered column allows for a 13-round capacity while maintaining a manageable grip size.
• Reliability: Equipped with a high-tensile strength steel spring and a low-friction follower to ensure consistent feeding from the first round to the last, crucial for dependable performance in the field.
• Witness Holes: The rear of the magazine body includes individual numbered ports, allowing you to check your remaining round count at a glance, providing quick situational awareness.
