Firing Pin Channel Liner – Striker Channel Sleeve for Pistol Slides (SKU 100002697)
Keep your striker-fired pistol running smooth and reliable with the Firing Pin Channel Liner (SKU 100002697). This small, critical sleeve lines the striker/firing pin channel inside the slide, helping guide the striker, reduce drag, and protect the slide’s interior from wear and solvent intrusion. If you’re rebuilding a slide, refreshing a hard-use training gun, or completing a new parts build, a fresh channel liner is a smart, low-cost upgrade that pays off in cleaner ignition, consistent primer strikes, and easier maintenance.
Engineered for factory-spec fit and made from durable, solvent-resistant material, the 100002697 channel liner installs flush and stays put—supporting reliable cycling session after session.
Why Replace Your Firing Pin Channel Liner?
Restore Smooth Striker Travel
Worn or contaminated liners can cause drag, light strikes, or sluggish resets. A new liner helps the striker glide cleanly for consistent ignition.
Protect Your Slide Interior
The liner provides a sacrificial, replaceable surface that shields the slide’s channel from carbon, debris, and harsh cleaning chemicals.
Improve Reliability After High Round Counts
Long training cycles, dry fire, and aggressive cleaning can fatigue the liner. Replacing it during periodic overhauls helps prevent intermittent misfires.
Essential for Slide Builds
If you’re assembling a slide from components, a quality channel liner is a must-have to complete the striker system correctly.
Budget-Smart Preventive Maintenance
Inexpensive part, big peace of mind—perfect to keep in an armorer’s kit or range bag as a spare.

Performance Benefits You’ll Notice
Consistent Primer Strikes
Reduced friction in the striker pathway supports uniform strike energy, helping resolve light-strike issues tied to liner wear or fouling.
Cleaner, Easier Maintenance
A serviceable liner limits solvent soak into the slide body and helps channel debris out during routine cleaning.
Long-Term Slide Protection
By acting as a replaceable interface, the liner helps preserve the channel geometry inside your slide—extending service life of the more expensive component.
High-Level Installation Overview
Unload & Clear: Remove magazine, lock slide back, and verify an empty chamber.
Disassemble Slide: Field strip and remove the striker assembly per your owner’s/armorer’s manual.
Remove Old Liner: Use the appropriate channel liner tool or dedicated extractor to withdraw the old sleeve. Avoid improvised tools that could gouge the channel.
Install New Liner: Lightly align and press the new liner straight in with a proper channel liner installation tool until fully seated and flush.
Reassemble & Function Check: Reinstall striker assembly, confirm free striker movement, and perform a dry function check before live fire.
If you’re new to striker assemblies, a qualified armorer/gunsmith can install the liner quickly and verify correct seating and striker travel.
Care & Maintenance
Keep the Channel Dry: After cleaning, ensure the channel is dry and free of heavy oil—excess lubricant attracts debris and can slow the striker.
Inspect During Deep Cleans: Look for peening, deformation, or heavy fouling. Replace liners at sensible intervals for duty/training guns.
Use Proper Solvents: Avoid harsh chemicals not intended for firearms; they can prematurely degrade polymer liners.
Frequently Asked Questions
Q: Do I really need a channel liner?
A: Yes—on platforms designed for it, the liner is essential for reliable striker travel and long-term slide protection.
Q: How often should it be replaced?
A: There’s no fixed round count. Many replace during major service intervals or when diagnosing light strikes, sluggish striker return, or visible liner wear.
Q: Can I install it without the special tool?
A: A dedicated channel liner tool is strongly recommended to avoid damaging the slide’s channel and to ensure the liner seats straight and fully.
Q: Will lubrication help?
A: Keep the channel clean and mostly dry. A dry or near-dry environment typically yields the most consistent striker performance.
Q: Is this compatible with aftermarket slides?
A: Most quality aftermarket slides that follow OEM geometry will accept standard liners. Always verify with the slide manufacturer.
