Glock 27 slides — OEM replacements for the subcompact .40 S&W pistol that delivers duty-grade terminal performance in Glock’s smallest double-stack package. The G27 was a standard backup and off-duty choice for law enforcement officers throughout the .40 S&W era, and it remains a top pick for concealed carriers who want serious stopping power in a deep-concealment pistol. Whether you’re replacing a worn slide, restoring a classic G27, or building a custom subcompact .40, you’ll find the right slide here.

Our inventory covers the Glock 27 Gen 3 OEM slide — the classic third-generation design with the proven Tenifer finish, Gen 3 rear serrations, and factory iron sights. This slide uses the standard Gen 3 single recoil spring assembly and Gen 3 internal components.

The G27 shares frame and slide dimensions with the G26 (9mm), G33 (.357 SIG), and G39 (.45 GAP) — but each is a different caliber platform. The .40 S&W breech face, barrel, and magazines are specific to this slide. Standard 9mm slides are not compatible. The G27 accepts G27 (9-round flush), G23 (13-round), and G22 (15-round) magazines, giving you flexibility from deep concealment to extended capacity.

Every slide in this category is machined to factory specifications, fit-tested before shipping, and backed by our fitment warranty. Whether you need a stripped slide shell for a custom build or a complete assembly that’s ready to install and shoot, we’ve got you covered.

Not sure if the Glock 27 slide fits your frame? This slide is designed for Glock 27 Gen 3 frames only. It is not compatible with Gen 4 or Gen 5 frames, and it is not compatible with standard 9mm Glock frames. Check the product description or contact us before ordering and we’ll confirm fitment for you.
