The Warne MEG422BLK Magazine Extension transforms the limited capacity of Glock 42 magazines by adding two additional rounds while maintaining the pistol's compact profile. This precision-machined extension addresses the primary limitation of subcompact pistols without compromising concealability or reliability.
What Makes This Different
Unlike polymer extensions that can crack under stress, this unit features 6061-T6 aluminum construction with hardcoat anodizing for superior durability. The precision engineering ensures consistent feeding geometry that matches factory magazine specifications. Independent testing shows the extension maintains factory-level reliability through thousands of loading cycles while adding minimal bulk to the pistol's grip.
Key Features
- Increases Glock 42 capacity from 6 to 8 rounds (.380 ACP)
- 6061-T6 aluminum construction with hardcoat anodized black finish
- Maintains original magazine spring and follower compatibility
- Adds approximately 0.75 inches to overall magazine length

Field testing demonstrates consistent feeding and ejection across various ammunition weights and manufacturers. The extension performs reliably in temperatures from -20°F to 140°F, making it suitable for duty carry, concealed carry, and competition use. The hardcoat anodizing resists wear from repeated holster draw cycles and maintains its finish through extended use.
