ETS Group SMKGLK4312 12-Round Extended 9mm Magazine for Glock 43

The ETS Group SMKGLK4312 extends your Glock 43's capacity to 12 rounds while maintaining the pistol's concealability. This smoke-colored polymer magazine addresses the common concern of limited capacity in subcompact carry pistols. The extended design provides additional grip surface without significantly increasing print profile.

What Makes This Different

Unlike steel magazines that add unnecessary weight, the SMKGLK4312 uses translucent polymer construction that allows visual round counting. The smoke finish reduces visibility of contents while maintaining the practical benefits of see-through design. At 12 rounds total capacity, it doubles the standard Glock 43 magazine capacity while adding minimal bulk to the grip frame.

Key Features

• 12-round capacity extends standard 6-round Glock 43 magazine
• Translucent smoke polymer construction for round counting
• Drop-free design with reliable feeding geometry
• Extended baseplate provides additional grip surface
• Compatible with factory Glock 43 magazine wells
• Lightweight polymer reduces carry weight compared to steel alternatives
• Easy disassembly for cleaning and maintenance

Field testing demonstrates consistent feeding with various 9mm ammunition types including hollow points and flat-nose bullets. The extended grip surface improves control during rapid fire sequences while maintaining compatibility with most Glock 43 holsters designed for extended magazines. The polymer construction resists corrosion in humid environments and extreme temperature variations.
