Designed to fit Glock 43X and Glock 48 (9mm)

Whether you run a Glock 43X or Glock 48 as a training pistol, a range companion, or as part of a broader Glock lineup, having a compatible extended magazine can add serious flexibility—especially for practice routines and high-volume shooting days.
Extended 28-round capacity: fewer reloads, more reps
A 28-round magazine transforms how your range sessions feel. Instead of constantly reloading between strings, you can stay focused on technique—trigger control, sight tracking, cadence, and transitions—while keeping the drill flow consistent.
A 28-round format is perfect for:
High-volume range practice and longer strings
Reload drills where you want fewer interruptions
Steel shooting and informal target sessions
Training days when you want more reps per magazine
For many shooters, extended magazines become dedicated “range mags,” offering maximum convenience while keeping standard-capacity mags reserved for other roles.
Steel construction for stability and durability
This magazine features steel construction, providing a rigid, solid-bodied feel that many shooters prefer—especially in extended-capacity formats where stability and consistent geometry can matter. Steel magazines are commonly valued for:
Strong structural integrity
Minimal flex during insertion and seating
A durable feel during repeated handling
Long-term usability in routine range conditions
If you like the classic confidence of a steel magazine body, the GLK-A23 is designed to deliver that sturdy, substantial feel.
Blued finish + black appearance: classic look, practical wear resistance
Finished with a traditional blued finish and presented in black, this magazine keeps a clean, subdued appearance that pairs naturally with Glock pistols and typical range gear. A quality finish supports:
Consistent appearance through handling and storage
A low-glare, understated look
Practical protection for a frequently handled component
It’s a classic aesthetic that fits almost any Glock build style—minimalist or accessory-forward.
Ideal uses: range, training, and high-volume practice
The ProMag GLK-A23 28-round magazine is a strong match for:
Training and drills
When you’re working structured routines—cadence drills, transitions, and performance-focused practice—extra capacity helps you stay in the drill longer and keep momentum.
Range days and recreational shooting
Extended mags shine for casual range sessions where convenience is the goal and you want to spend less time loading and more time shooting.
Magazine rotation and loadout flexibility
Many shooters keep a mix of magazines: standard-capacity for general use, plus extended mags for range efficiency. Adding a 28-round option gives you another tool in the kit.
