FN Herstal Holsters

FN Herstal — Fabrique Nationale d'Armes de Guerre — is one of the world's oldest and most respected firearms manufacturers, with origins in Liège, Belgium dating to 1889. FN has been a primary supplier to NATO militaries and law enforcement agencies for well over a century, producing everything from the iconic FN FAL and M249 SAW to the Five-seveN pistol and the M1911A1 during World War II. FN's American headquarters in Columbia, South Carolina, is where the FN 509 — their flagship striker-fired service pistol — is manufactured. Adopted by law enforcement agencies and trusted by civilian carriers, the FN 509 brings military-grade engineering to the everyday carry market. The 509 Compact MRD packs a 15-round magazine into a carry-friendly package with an optics-ready slide, while the 509 Tactical adds a threaded barrel and suppressor-height sights for those who run suppressors or accessories.

FN pistols have a specific holster requirement worth understanding: the FN 509's slide is wider and dimensionally different from comparably sized pistols like the Glock 19, meaning cross-compatible holsters don't work reliably. Additionally, the variety of 509 configurations — standard, Compact, Midsize, Tactical — each have a different barrel length. KSG Armory forms every FN holster over the actual firearm, ensuring your specific 509 variant gets a holster built exactly to its geometry, not an approximation based on a similar-sized gun.
