The Unlocking Block Pin Set for FN 509 & FNS-C Pistols solves a specific problem for Arizona shooters: factory solid pins that are a pain to remove after exposure to high heat, dust, and carbon buildup. This set replaces the factory solid front unlocking block pin with a coil pin designed for easy service access without fighting stuck components.
Made for the shooter who runs their pistol hard in desert conditions, this pin set handles the real-world demands of suppressed fire, extended range sessions, and the fine grit that finds its way into every action. Each pin has been test-fired through thousands of rounds of live ammunition with no bending or walking out. That means you spend less time at the bench and more time on target.
- Direct replacement for the factory front unlocking block pin on FN 509 and FNS-C pistols
- Coil pin design installs and removes easily for thorough cleaning and inspection after dusty or suppressed use
- 3 pins per package because we recommend using a fresh pin each time you remove it for service
- 100% made in the USA from highest quality materials
- Install direction: remove right to left, install left to right (same as factory pin)
For shooters running suppressors, the increased carbon fouling and heat can make standard solid pins difficult to drift out. This coil pin gives you a clean removal path without hammering or damaging your frame. Same goes for cleaning after a day shooting in the dust — pop the pin, pull the slide, and get your gun back together fast.
Specs & Fitment:
Compatible with FN 509 series (all variants) and FNS-C pistols. Price: $15. Category: FN Triggers & Trigger Kits. Each pin is a single-use component — replace when removed for service. The three-pin set gives you a spare for future maintenance cycles. No modification required to your pistol; this is a drop-in replacement for the factory front unlocking block pin.
For the Arizona desert shooter who maintains their own gear, this pin set is a practical upgrade. Less friction during disassembly, reliable retention under recoil, and made to handle the heat.
