Sold Out
A Glock 26 Gen 3 slide assembly, built in-house at 3CR Tactical — machined from 416 stainless, finished in salt-bath black nitride, with a lightening window that cuts reciprocating mass and shows the barrel through the top of the slide, with front and rear cocking serrations and the RMR footprint cut directly into the slide with a cover plate installed. Assembled with a crown-cut black nitride 9mm barrel, standard-height polymer sights, and the full 3CR Tactical slide completion kit.
What's included
Fitment — Glock 26 Gen 1–3 frames and third-party subcompact frames built to the same pattern (including Polymer80 PF940SC). Use a Gen 3-spec recoil spring assembly; Gen 4/5 recoil assemblies use different geometry.
Optic & cover-plate hardware: RMR footprint (Trijicon RMR, Holosun 407C/507C, SRO and similar). Screw specs for reference: cover plate 6-32 × 1/3″, optic 6-32 × 7/16″. Optic sold separately.
Frame parts kit included
This build is bundled with the Glock 26 Gen 3 lower parts kit — the lower components needed to finish a frame, bundled below what the kit sells for on its own.
Not included: the locking block itself. Polymer80 frame kits ship with their own locking block; for a factory frame, reuse yours or add one separately.
What you'll still need to supply
This is a slide assembly and a frame parts kit. It is not a complete pistol and does not include a frame.
