This is a spring-loaded disassembly punch with a 3/32″ flat tip, modified specifically to address the common difficulty of removing the front locking block pin on FN 509, FN 510, and FN 545 pistols. The factory pin is under spring tension and often requires multiple impacts with a hammer and standard punch, risking frame damage or pin deformation. This component applies direct, repeatable force to the pin face, freeing it with a few strikes when properly aligned. It replaces the need for a separate hammer and punch during detailed frame disassembly.
Compatibility
- FN 509 (all variants, including Compact, LS Edge, MRD, and Tactical)
- FN 510 (all variants)
- FN 545 (all variants)
- Designed for use with the Apex Disassembly Fixture for FN 509/FNS-C (recommended, sold separately)
Key Features
- Flat tip geometry prevents pin walking or slipping off the pin face.
- Spring-driven mechanism delivers consistent impact force without requiring a hammer.
- Anvil rings provide a stable grip point for one-handed operation.
- 3/32″ diameter fits the front locking block pin bore on listed FN pistols.
- Reduces disassembly time and frame wear compared to traditional punch-and-hammer methods.
Install Difficulty: 1/5
Tools required: Safety glasses, Apex Disassembly Fixture (recommended), solid work surface (bench leg or concrete floor). No hammer or standard punch needed. Procedure: unload and field strip pistol per factory manual, remove take-down lever, mount frame in fixture, align punch tip to front locking block pin, and strike the anvil while holding the punch steady. See manufacturer video for alignment details.
FAQ
Do I need the Disassembly Fixture to use this punch?
Not strictly, but the fixture provides proper alignment and stabilizes the frame. Without it, you risk misaligning the punch or damaging the frame. We strongly recommend using the corresponding Apex Disassembly Fixture for your pistol.
Can this punch be used on other FN models like the FNS or FNX?
This 3/32″ punch is designed specifically for the front locking block pin on FN 509, 510, and 545 pistols. It may not fit other models due to different pin diameters or frame geometry. Verify compatibility before use.
How many hits does it take to remove the pin?
Typically 2–4 firm strikes on the anvil rings while the punch is properly aligned. Results vary depending on how tight the pin is seated and the condition of the frame. If the pin does not move after several hits, re-check alignment and ensure the frame is fully seated in the fixture.
