ETS GLK-439 9mm Magazine 9rd Glock 43 Clear Polymer

The ETS GLK-439 magazine transforms the Glock 43 shooting experience with its crystal-clear polymer construction and enhanced visibility features. This 9-round magazine allows shooters to instantly verify ammunition count and identify potential feeding issues through its transparent body.

What Makes This Different

Unlike traditional opaque magazines, the GLK-439 features ETS Group's proprietary clear polymer that maintains structural integrity while providing complete visual access to ammunition. The material resists cracking and stress fractures that plague inferior clear magazines. Advanced polymer chemistry delivers impact resistance comparable to factory Glock magazines while weighing 15% less than steel alternatives.

Key Features

• Crystal-clear polymer construction for instant round count verification
• 9-round capacity optimized for Glock 43 pistols
• Drop-free design with enhanced magazine release compatibility
• Reinforced feed lips prevent deformation under spring pressure
• Witness holes molded into body for quick ammunition assessment
• Anti-tilt follower ensures reliable feeding geometry
• Heat-treated steel spring rated for 10,000+ compression cycles

Field testing demonstrates consistent feeding across various 9mm ammunition weights from 115gr to 147gr. The magazine functions reliably in temperatures from -20°F to 140°F without feed lip expansion or follower binding. Law enforcement agencies report zero malfunctions during qualification courses, while competitive shooters appreciate the ability to track round count during rapid-fire stages.
