ETS Magazine for Glock 27, .40 S&W, 9-Round Capacity, Durable Polymer Construction

The ETS Magazine for Glock 27 in .40 S&W with 9-round capacity delivers the reliability you expect from a modern polymer mag without the premium price tag. Built by Elite Tactical Systems Group using their proven Advanced Transparent Polymer — the same material behind their popular AR15 magazines — this pistol magazine combines see-through construction with real-world durability. Whether you're stocking spares for duty carry, competition, or the range, the ETS Glock 27 mag earns its place in your kit through transparent design and zero-compromise engineering.

The transparent polymer walls let you track your round count and ammo type at a glance from any angle, eliminating the guesswork on reloads. The specially designed base plate features a grip rib for positive extraction, and the mag reliably locks the slide back when empty — performance parity with OEM Glock magazines. Disassembly for cleaning is straightforward, and the mag plays well with aftermarket base plates if you want to customize your setup.

ETS stress-tested this mag through thousands of rounds across multiple Glock generations and ammo types (including hollowpoints) without failure. The polymer itself has been hammered: repeated 8-foot drops fully loaded, thermal swings from -60 to 180°F, months of UV exposure, and chemical resistance to solvents, fuels, and insect repellent. The result is a magazine that won't creep or spread even when stored fully loaded, and won't become brittle or crack under field abuse.
