Glock Factory Magazine Gen 4 for Glock 27 - .40 S&W, Polymer, Black

The Glock Factory Magazine Gen 4 for Glock 27 is a genuine OEM magazine built to the same exacting standards as your pistol. If you carry a Glock 27 in .40 S&W, running factory mags isn't just convenient—it's the smart choice. You know your gun will cycle them reliably, and Glock's decades of testing back every round. This is the magazine that comes out of the box with your G27, and for good reason.

The G27 magazine uses Glock's time-proven hybrid construction: a hardened steel core wrapped in high-tech polymer. That combination lets it shrug off the punishment that comes with duty carry, range time, or defensive training. Whether it's dropped, loaded hard, or stuffed in a duty belt for hours, this mag will feed on demand. The 10-round capacity pairs perfectly with the G27's compact frame, giving you a magazine that actually fits your gun's ergonomics instead of printing awkwardly.

For concealed carry, sport shooting, or professional use, standardizing on factory Glock magazines eliminates variables. No guessing about compatibility, break-in periods, or whether an off-brand follower will hang up under pressure. Black polymer finish resists corrosion and blends seamlessly with your gear. If you're serious about your G27, this is the only magazine you should trust for duty or carry rotation.
