Fowler Industries OEM Gen 3/4 G17 Mk 2 slide.

Our OEM slide is designed to be backwards compatible with between generation 3 and 4 Glock pistols. These slides are held to the tightest tolerances possible and manufactured from the ground up on 5-Axis CNC machines. We chose to manufacture our own slides to better serve the end user with shorter wait times and better overall consistency.

All OEM Fowler Industries slides ship our facility without internals (channel liner IS installed).

Cerakote options are available. Please note that most common Cerakote options will add approximately two weeks to delivery time.

Our slides carry a lifetime warranty and are proudly manufactured in the United States.

Material: 4130

Finish: Black Nitride

Compatibility: Gen 3/4 G17 (and Gen 5 if end plate is swapped)

*Note: add Gen 4 adapter ring if you plan on using this slide on a Gen 4 frame (this bridges the gap between the dust cover, while not necessary, it makes the slide/frame fit look better). Gen 3 guide-rod must be used.


Do you have an OEM Glock slide that you no longer use? For the first time ever, we are offering trade-in credit for our Mk 1/2 slides.

We offer $130 trade in value for good condition, stripped, OEM Glock slides. Basically - send us your OEM Glock slide, and you'll save $130 on your new FI slide.

Trade in program applies only to OEM FI slides (not customer submitted pistols/slides). All trade in program slide exchanges must be handled via e-mail (, or via phone.
