FAQ
Will this fit a standard FN 509?
No. This release is specifically for Large Frame FN pistols (FNX-45, FNX-40, FNS-45, FNS-40, FN 545, FN 510). The 509 uses a different frame geometry and release interface.
Do I need to modify the frame to install it?
No. It is a direct drop-in replacement for the factory release. Remove the slide, drift out the retaining pin, swap releases, and reinstall the pin. No filing, sanding, or permanent changes required.
Is this ambidextrous?
No. It is a single-sided release. You select either left-hand or right-hand configuration at time of purchase. If you need ambidextrous operation, this part is not compatible with that setup.
