The ProMag GLK-A27 is a 17-round magazine purpose-built for the Glock 28 in .380 ACP. If you carry or shoot a Glock 28, this magazine gives you genuine capacity where factory options leave you short. The GLK-A27 pairs a reliable polymer construction with proven ProMag engineering—the kind of mag that earns trust through straightforward performance, not marketing noise.
Glock 28 owners often find themselves trading capacity for shootability. This magazine solves that trade-off: 17 rounds means more time on target, fewer reloads on the range, and genuine versatility whether you're practicing for duty, sport shooting, or personal defense. The black polymer body resists corrosion and handles rough handling without complaint—exactly what you need from a working magazine.
ProMag has been making aftermarket magazines for decades. They're not the OEM, but they understand what shooters actually need: reliability you can count on, build quality that matches the price, and simple, no-excuses functionality. If your Glock 28 lives in your holster or your range bag, the GLK-A27 is the practical upgrade that extends your shooting day without drama.
