Frequently Asked Questions (FAQs) About FN 509 Magazines
Are FN 509 magazines interchangeable across all models?
Yes. Factory 509 magazines are cross-compatible with every FN 509 variant—including Compact, Midsize, Tactical, LS Edge, and CC Edge—as long as you match capacity and baseplate length to your grip size.
Can I run FN 509 magazines in an older FNS-9?
Generally, no; the latch cut differs. Some users have adapted FNS mags to 509s by swapping baseplates, but the reverse isn’t reliable and is not recommended for defensive use.
