Overview

Built for shooters completing a Polymer80 frame or upgrading an existing Glock 19 Gen 3 or Gen 4 setup, this slide offers a purpose-driven option for a custom pistol build. It includes Agency Arms’ knurled finish and the Agency Optic System, giving the platform a more tailored foundation for a modern carry or range-focused configuration. The slide is supplied stripped, with only a channel liner included, so it requires the remaining internal parts to complete the assembly. An all-black DLC coating gives it a clean, understated appearance suited to serious use.

Considerations & Trade-offs

  • This slide is sold completely stripped, so all internal parts still need to be sourced separately before the build is complete.
  • It is designed specifically for Glock 19 Gen 3 and Gen 4 models, so compatibility is limited to that platform.
  • The optic-ready Agency Optic System adds flexibility, but it also means the slide is intended for a build that includes an optic setup.
  • The all-black DLC finish and knurled exterior are part of the package, but the product description does not include any performance claims beyond those features.
