Are Glock 19 and 17 slides the same?

No, Glock 19 slide is not the same as Glock 17 in terms of barrel locking lug specs, length, and fit.

In addition, A GEN 3 Glock 19 slide will not fit on a GEN 4 Glock 19 frame or GEN 5.

If you are wondering if you can swap an aftermarket optic-ready Glock 19 slide to fit on a Glock 17 to save money buying another slide, you may just have to purchase another dedicated optic ready slide.

What's Different:

are glock 19 slide the same as glock 17

Glock 17 VS Glock 19 Slide Overall Length: 7.95" VS 7.28"

Glock 19 uses a different length recoil spring than the G17

Aren't G19 frame the same as G17 frame, but slightly shorter?

G19 and G17 have the same overall design, but the G19's barrel locking lugs have a different spec than the G17.

This goes the same for Glock 23 and Glock 22.

For users that like the Glock 17 full size frame, but want G19 length barrel. Please check out Glock 19X.

At the time of writing this content, the G19X Gen 5 availability is very limited. Please check PSA's website to see if they have one in stock.

If not, please check out ZEV OZ9 or Shadow System MR920.
