Glock Model 20 10mm Magazine, 15-Round Capacity

Glock Model 20 Magazine: 15-Round 10mm Capacity

This is the factory-original magazine for Glock's Model 20 10mm pistol—the standard-capacity option that gives you serious firepower in a reliable, drop-free design.

Construction & Durability

Glock builds these magazines from high-resistance, lightweight polymer reinforced with full-length steel inserts. The result is a magazine that resists deformation even when dropped from significant heights. Internal components include hardened steel springs engineered for consistent feeding and reliable performance.

Features

• 15-round capacity for 10mm Auto ammunition
• Drop-free design for quick magazine changes
• Numbered witness holes on the side so you can count remaining rounds at a glance
• Crack-resistant polymer shell with steel reinforcing for durability
• Full-length steel spring for reliable feeding

Break-In Period

New Glock magazines can be stiff when first used. Load the magazine with all but the last round and let it sit for a few days to allow the spring to compress. Cycling the magazine from full to empty multiple times will also speed the break-in process. After this period, the magazine will function smoothly and reliably.

The Right Choice

Whether you're a hunter, sport shooter, or looking for a serious home defense option, this factory magazine delivers the capacity and reliability Glock is known for.
