TacFire Replacement Slide – 9mm Luger – Stainless Steel – Graphite Black Cerakote – Optics Cut & Ported – For Glock® 19 Gen3 (GLKSL19G2) – UPC 686294505317
Upgrade your G19 build with durability, speed, and modern optics compatibility. The TacFire Replacement Slide for Glock 19 Gen3 (model GLKSL19G2) is precision-machined from stainless steel, given a tough Graphite Black Cerakote® finish, and factory optics-cut with slide ports to reduce reciprocating weight. Whether you’re refreshing a duty-worn slide, completing a Polymer80-style project, or assembling a competition-ready top end, this 9mm replacement slide provides a clean foundation for reliable cycling and red-dot performance.
Why this TacFire slide stands out
Stainless steel construction: Rigid, corrosion-resistant steel resists peening and maintains critical dimensions for smooth, repeatable operation.
Graphite Black Cerakote: A premium ceramic coating that adds abrasion resistance, chemical resilience, and a low-glare professional look.
Optics-ready from the start: Factory optic cut accepts a popular micro red-dot footprint (RMR/Holosun-style in many listings; verify footprint for your batch) so you can mount a dot without sending the slide to a mill.
Performance slide ports: Strategic porting trims reciprocating mass, promoting faster cycle speed perception and flatter tracking (with proper spring/ammo tuning).
Glock 19 Gen3 compatibility: Designed around the proven Gen3 pattern for broad parts compatibility and easy sourcing of internals.
Build-friendly value: Start with a quality slide and add the exact barrel, sights, and small parts you prefer.
Note: Optic footprint and included mounting hardware can vary by production batch. Always verify the footprint and screw lengths before installation to avoid damaging your optic or slide.
Ideal use cases
EDC & defensive builds: Pair with your preferred tritium or fiber-optic sights and a closed-emitter dot for modern defensive performance.
Competition & training: Ported top helps reduce slide mass for fast return to zero with tuned recoil springs and match loads.
Refurbish & refresh: Replace a battered OEM slide and reuse your existing G19 Gen3 barrel and internals (or upgrade as you go).

What to expect during your build
Slide status: Typically sold as a stripped slide (no barrel, sights, or small parts), letting you choose premium components.
Internals: Use Glock-pattern Gen3 slide parts: striker assembly, extractor, plunger, channel liner, back plate, etc.
Barrel: Standard G19 9mm barrel (threaded or non-threaded).
Sights: Dovetail cuts fit many Glock-pattern sights; co-witness heights depend on your optic and plate (if used).
Optic mounting: Confirm footprint and torque specs. Use appropriate blue threadlocker on screws and verify clearance with the extractor depressor plunger channel.
Tip: Always install a new channel liner when assembling a slide. A simple channel-liner tool makes the job quick and ensures proper striker movement.
Installation & zeroing tips
Unload/clear your firearm and work on an empty bench.
Assemble slide internals and barrel/recoil spring per Glock-pattern procedures.
Mount optic with verified screws/torque; witness-mark screws to monitor movement.
Function check (striker safety, reset, slide travel).
Range-test with your carry/competition ammo; tune recoil spring weight if necessary for ported slides.
Benefits you’ll notice
Smoother dot tracking: Ported/lightened profile promotes quick return to sight picture with appropriate spring and ammo pairing.
Weather-ready durability: Stainless steel + Cerakote stand up to sweat, rain, and long training days.
Cleaner presentation: Graphite Black blends with frames, lights, and suppressor-height sights for a modern, cohesive look.
Frequently asked questions
Q: Which optics fit the cut?
A: Many batches are RMR/Holosun-pattern. Please verify the exact footprint and included screws for your production run before mounting.
Q: Is this for Gen3 only?
A: It’s engineered around the Glock 19 Gen3 spec. Some cross-gen compatibility exists with additional parts, but for best results pair with Gen3 components.
Q: Is the slide complete?
A: Most TacFire slides ship stripped. You’ll need sights, barrel, and Gen3 slide internals. Check your retailer’s listing for exact contents.
Q: Do the ports vent gas like a compensated barrel?
A: The slide ports reduce slide mass; gas redirection requires a ported or compensated barrel. You can run this slide with standard or ported barrels.
Q: Does Cerakote affect tolerances?
A: The coating is thin and applied professionally; critical bearing surfaces are maintained for proper function.
