Elite Tactical Systems (ETS) Magazine Glock 21 .45 ACP 30/rd - For Glock 21 30 41

The Elite Tactical Systems (ETS) Magazine Glock 21 .45 ACP 30-round magazine is purpose-built for operators and defensive shooters who demand extended capacity without compromising reliability. This 30-round magazine serves law enforcement, military, and civilian tactical users who require sustained firepower in high-stress environments. The .45 ACP platform remains a popular choice for stopping power in close-quarters combat, and this extended-capacity solution addresses the limitations of standard-capacity alternatives.

ETS magazines are engineered with witness holes along the spine, allowing shooters to verify round count at a glance during tactical reloads or magazine checks. The follower and spring geometry is optimized to handle the 30-round capacity while maintaining consistent feeding through the Glock 21's feed ramp—critical for duty and defensive applications where feeding failures are unacceptable. Manufactured to ISO standards with reinforced polymer construction and a proven feed-lip design, this magazine delivers the durability expected in military and law enforcement supply chains.

This magazine is fully compatible with Glock 21 platforms (including Gen 3, Gen 4, and Gen 5 variants) and will also function in Glock 41 models due to shared magwell geometry. Operators running carbine-length .45 conversions will benefit from the extended capacity of this magazine. Its compact footprint remains practical for duty belts and tactical rigs despite the expanded capacity.
