Are Glock 19 and 17 slides the same? This is essentially a comparison between Glock 17 and 19 slides, but we'll focus solely on slide distinctions here.

No, the Glock 19 slide differs from the Glock 17 slide in terms of barrel locking lug specifications, length, and compatibility.

Moreover, a GEN 3 Glock 19 slide won't fit on a GEN 4 Glock 19 frame or GEN 5 frame.

If you're thinking about swapping an aftermarket optic-ready Glock 19 slide onto a Glock 17 to save money, you might need to buy a dedicated optic-ready slide instead.
