Disassembly Punch – 3/32″

Every FN 509, 510, or 545 owner knows that the front locking block pin can be a stubborn piece of work. That’s where the disassembly punch – 3/32″ from Apex comes in. It’s a spring-powered pin punch, modified with a flat tip to deliver concentrated force directly to the pin face. With just a few deliberate strikes, it pops the pin free—no wrestling, no marred frames, no frustration.

Key Features

• Spring-Powered Design – WHY IT MATTERS: The internal spring stores energy as you press, then releases it in a controlled burst. This eliminates the need for a heavy hammer swing, giving you precision and repeatability even in tight spaces.
• Flat-Tip Modification – WHY IT MATTERS: Apex grinds the tip flat to match the pin face geometry. This ensures full contact and maximum energy transfer, reducing the chance of slippage or damage to the pin or frame.
• FN-Specific Fit – WHY IT MATTERS: Engineered for the front locking block pin on FN 509, 510, and 545 pistols. It aligns perfectly with the pin axis, so every hit drives the pin straight out—no angled tapping or guesswork.
• Compact and Portable – WHY IT MATTERS: At just over 4 inches long and weighing less than an ounce, it stows easily in a range bag or tool roll. Always have it when you need it.

Who It’s For

This punch is for the shooter who maintains his own firearms—the guy who appreciates a tool that does one thing and does it well. Whether you’re a competition shooter cleaning after a match, a gunsmith working on multiple FN pistols, or a collector who values original finish, this tool saves time and protects your investment. It’s also a smart addition for anyone who’s ever fought a stubborn locking block pin and wishes for a better way.

FAQ

How to take apart a 3×3?

The term “3×3″ can refer to different things, but if you’re asking about disassembling a 3×3-inch locking block pin setup (common on some compact pistols), the process is similar to the FN 509/510/545. First, ensure the firearm is unloaded and clear. Use the Apex Disassembly Punch 3/32” aligned squarely with the pin face. Press firmly to compress the spring, then release—the punch will drive the pin out. For best results, pair it with the Apex Disassembly Fixture for your specific pistol model.

Will this punch work on other FN models?

Per Apex specs, this punch is designed specifically for the front locking block pin on FN 509, 510, and 545 pistols. It may not fit or function correctly on other models like the FN FNX or FNS series. Always verify compatibility before use.

Do I need a hammer with this tool?

No. The spring-powered mechanism stores energy as you press, then releases it to drive the pin out. A few firm presses are all that’s required—no hammer needed.

Can I use this punch for other pins on the pistol?

We recommend sticking to the front locking block pin. The flat tip and spring power are optimized for that specific pin. Using it on other pins could cause damage or misalignment.
