ProMag GLKA23 28-Round 9mm Magazine for Glock 43X/48 Blued Steel

The ProMag GLKA23 transforms compact Glock 43X and 48 pistols into high-capacity platforms with its 28-round 9mm magazine capacity. This extended magazine maintains the slim profile that makes these pistols ideal for concealed carry while dramatically increasing firepower for competitive shooting and tactical applications.

What Makes This Different

Unlike standard 10-round factory magazines, the GLKA23 nearly triples ammunition capacity without requiring grip modifications or frame alterations. The blued steel construction provides superior durability compared to polymer alternatives, with heat-treated components rated for thousands of loading cycles. The magazine's engineering maintains reliable feeding geometry despite the extended length, using a proven spring system that prevents follower binding.

Key Features

• 28-round capacity increases standard magazine capacity by 180%
• Blued steel construction with heat-treated internal components
• Compatible with Glock 43X and Glock 48 pistols without modification

Range testing demonstrates consistent feeding with various 9mm ammunition weights from 115 to 147 grains. The extended length makes this magazine particularly suitable for competitive shooting disciplines where maximum capacity provides tactical advantage. Law enforcement agencies have adopted similar high-capacity magazines for patrol rifle applications where increased ammunition supply proves critical. The steel construction withstands repeated dropping on concrete surfaces without cracking or dimensional changes that affect reliability.
