ETS GLK2030 30-Round Extended Magazine 10mm Auto Glock 20/29/40

The ETS Group GLK2030 extended magazine transforms Glock 10mm pistols into higher-capacity platforms without sacrificing reliability. This 30-round magazine extends shooting sessions and reduces reload frequency for competitive shooters and professionals who demand maximum ammunition capacity.

What Makes This Different

Unlike traditional steel magazines, the GLK2030 features translucent polymer construction that allows instant visual ammunition counts. The extended body maintains the same feed geometry as factory magazines while tripling capacity. ETS magazines undergo drop testing from 8 feet onto concrete and function testing through 10,000+ round cycles to ensure consistent performance.

Key Features

• 30-round capacity increases firepower 3x over standard 10-round magazines
• Clear polymer body enables quick visual ammunition assessment
• Compatible with Glock models 20, 29, and 40 in 10mm Auto
• Reinforced feed lips prevent deformation under spring pressure
• Anti-tilt follower design ensures smooth cartridge presentation
• Removable floor plate allows complete disassembly for cleaning
• Chemical-resistant polymer withstands cleaning solvents and lubricants

Field testing demonstrates reliable feeding across various 10mm loadings, from 155-grain hollow points to 200-grain hard-cast bullets. The extended magazine proves valuable for competitive shooting disciplines requiring high round counts, tactical training scenarios, and hunting applications where follow-up shots matter. Temperature cycling from -20°F to 120°F shows no impact on spring tension or feeding reliability.
