ProMag GLKA22 20-Round 9mm Magazine for Glock 48/43X Blued Steel

The ProMag GLKA22 delivers extended capacity for Glock 48 and 43X pistols without compromising concealment or reliability. This 20-round magazine transforms single-stack platforms into higher-capacity defensive tools while maintaining the slim profile that makes these pistols ideal for concealed carry.

What Makes This Different

Unlike factory 10-round magazines, the GLKA22 nearly doubles ammunition capacity through an extended body design that maintains compatibility with existing holsters and carry setups. The blued steel construction provides corrosion resistance and structural integrity under repeated loading cycles. ProMag's spring system delivers consistent feeding pressure across all 20 rounds, addressing the common failure point in extended magazines.

Key Features

• 20-round capacity increases firepower by 100% over factory magazines
• Blued steel body construction resists corrosion and impact damage
• Heat-treated spring maintains tension through 500+ loading cycles
• Compatible with Glock 48 and Glock 43X pistols exclusively
• Extended baseplate provides secure grip during tactical reloads
• Anti-tilt follower prevents feeding malfunctions and double-feeds
• Removable floorplate allows disassembly for cleaning and maintenance

Range testing demonstrates reliable feeding with standard pressure 9mm ammunition including 115-grain, 124-grain, and 147-grain loads. The magazine functions consistently in competitive shooting scenarios where rapid reloads and high round counts are essential. Law enforcement agencies have adopted similar extended magazines for backup weapon systems where additional capacity provides tactical advantages.
