TACFIRE UPK-GLK-19 GLK19 G3 SLDE UPPER Part KIT with stainless steel guide ROD UPC 659725382771
Product Description
The Tacfire Glock 19 Gen 3 Upper Parts Kit (UPK-GLK-19) is a complete, high-performance slide internals package designed to finish factory or aftermarket Glock 19 Generation 3 stripped slides. Engineered for high-volume shooting, custom slide builds, and bench overhaul projects, this slide completion kit includes every internal component required to build a functional, reliable upper assembly.
Highlighting this kit is an upgraded stainless steel recoil guide rod assembly, providing superior rigidity, reduced flex, and smoother slide cycling compared to standard factory polymer guide rods. Each individual internal component—including the striker/firing pin, safety plunger, extractor, spring load bearing, back plate, and associated high-tensile springs—is precision-machined from heat-treated steel and corrosion-resistant alloys to meet or exceed OEM dimensional tolerances.
Whether you are assembling a custom compact slide build from scratch, restoring a worn duty slide, or keeping spare bench internals staged for emergency repairs, the Tacfire UPK-GLK-19 kit delivers drop-in fitment, crisp ignition, and long-term cycling reliability.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct drop-in fitment for factory and aftermarket 9mm Glock 19 Gen 1-3 stripped slides (also compatible with G19-length custom slides such as Polymer80 PF940C builds). Not compatible with Gen 4/5 slides or slimline frames.
- Perform a complete safety check: drop the magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Install the channel liner into the slide firing pin channel using a dedicated channel liner insertion tool.
- Assemble the striker/firing pin with the striker spring, spring cups, and sleeve; slide into the firing pin channel.
- Depress the safety plunger and slide the extractor, spring load bearing assembly, and spring into their respective slide bores.
- Install the slide cover plate by depressing the firing pin sleeve and spring-loaded bearing until the plate clicks flush into position.
- Insert the stainless steel recoil guide rod assembly into the slide lug channel, install the slide assembly onto your frame, and perform complete function/safety checks.
