Glock 34 slides — factory-original and optics-ready options for Glock’s flagship competition long-slide pistol. The G34 is the dominant platform in USPSA Carry Optics and IDPA, trusted by competitive shooters for its extended sight radius, reduced muzzle flip, and Marksman Barrel accuracy. Whether you’re replacing a worn slide, upgrading to a red dot, or building a custom competition pistol, you’ll find the right slide here.

Our inventory covers the major G34 configurations: the Glock 34 Gen 5 MOS slide with the 5.31-inch Marksman Barrel, nDLC finish, front and rear serrations, and a factory MOS cut for full-size red dots; and the Glock 34 Gen 5 OEM slide in standard iron-sights configuration. Gen 5 slides use the Gen 5 dual recoil spring assembly and include the ambidextrous slide stop cut.

The G34 is a long-slide 9mm — 8.15 inches of slide length with a 5.31-inch barrel. It is not compatible with standard G17 or G19 barrels; always use a G34-specific barrel. The G34 shares frame dimensions with the G17, but the extended slide is what defines the competition platform.

Every slide in this category is 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 which Glock 34 slide fits your frame? Gen 5 G34 slides require Gen 5 G34 frames and use the Gen 5 dual recoil spring assembly. They are not compatible with Gen 3 or Gen 4 frames, and they require a G34-length barrel. Check the product description or contact us before ordering and we’ll confirm fitment for you.
