Glock 48 slides — OEM and MOS optics-ready options for Glock’s full-grip Slimline pistol. The G48 combines the slim 1.10-inch width of the G43X with a full-length grip — delivering better control and a more substantial feel than the shorter-grip Slimline. It’s one of the most popular concealed carry platforms for shooters who want a full firing grip without going to a double-stack frame. Whether you’re replacing a worn slide, upgrading to a red dot, or building a custom Slimline pistol, you’ll find the right slide here.

Our inventory covers the Glock 48 OEM slide with the factory Silver PVD finish and standard iron sights, and the Glock 48 MOS slide with an RMSc optic cut for direct mounting of micro red dots. Both use the Slimline-specific dual recoil spring assembly.

The G48 shares identical slide and barrel dimensions with the G43X — the only difference is grip length. This means G48 and G43X slides are interchangeable between the two frames. The slide is what you choose for optics capability; the frame is what you choose for grip length. Whether you want a 43X-length grip or a 48-length grip, the same slide works on either.

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 if the Glock 48 slide fits your frame? The G48 slide fits both G48 and G43X frames — they share identical slide dimensions. It is not compatible with standard double-stack Glock frames (G19, G17, G26) or with the original G43. Check the product description or contact us before ordering and we’ll confirm fitment for you.
