Custom KYDEX® Holsters for the FN 509C X300
An FN 509C with a Surefire X300 is the compact wearing the duty standard — carry-frame concealment with no compromise on the light, the configuration for people who train with the X300 and see no reason to switch. ANR Design molds our KYDEX® holsters over the exact pairing in Manchester, NH, with dedicated fitments for both the X300U-A and X300U-B, housing fully enclosed, retention locked on the gun, optics and suppressor-height sights cleared as standard. And this combination qualifies for our fastest Quick Ship tier in both right- and left-handed builds. Configure yours below in IWB or OWB.

FN 509C + X300 Fitment Details
This holster is molded over the actual pairing — FN 509 Compact or 509C Tactical with the Surefire X300U-A or X300U-B mounted, on the 509C shell. The light housing is fully enclosed, the draw stays smooth with no bezel snag, and retention clicks on the trigger guard rather than clamping the light. Mounted optics and suppressor-height sights clear as standard.
Frequently Asked Questions
What’s the difference between the X300U-A and X300U-B — and which do I select?
The A and B differ in how they mount: the U-A uses Surefire’s quick-release rail latch, the U-B a T-slot screw mount. We mold a dedicated fitment for each — select the exact version you run in the builder and retention will lock correctly.
Is the 509C X300 holster Quick Ship eligible?
Yes — both the U-A and U-B combinations qualify for our fastest Quick Ship tier in right- and left-handed builds, IWB or OWB. The builder shows your exact lead time before you order.
Will this fit my 509C Tactical with the threaded barrel and an X300?
Yes — the shell covers both trims, threaded barrel riding through the open muzzle, with tall sights and mounted optics clearing as standard.
Will a full-size FN 509 X300 holster fit the Compact with the same light?
No — the compact frame is its own geometry, and the shell molds around both the gun and the light. Each pairing gets its own dedicated fitment; select your exact gun in the builder.
What warranty comes with it?
