Custom KYDEX® Holsters for the FN 509 LS Edge X300U A/B
The FN 509 LS Edge with a Surefire X300 is the full-size statement — five inches of competition slide under the duty-light standard, the configuration for shooters who see no reason to choose between match features and working output. ANR Design molds our KYDEX® holsters over the exact pairing in Manchester, NH, with dedicated fitments for both the X300U-A and X300U-B (X300 Ultra) — housing fully enclosed, the long slide covered to the muzzle, retention locked on the gun, LPOMS optics and tall 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 OWB or IWB.

FN 509 LS Edge + X300 Fitment Details
This holster is molded over the actual pairing — FN 509 LS Edge with the Surefire X300U-A or X300U-B mounted, on the LS Edge’s dedicated long-slide 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, and the flared magwell rides above the shell.
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 LS Edge 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, OWB or IWB. The builder shows your exact lead time before you order.
Will this fit my LS Edge with a red dot and the X300 together?
Yes — the shell clears LPOMS-mounted optics and suppressor-height sights as standard, so the full dot-and-light setup carries without modification.
Will a standard FN 509 X300 holster fit the LS Edge with the same light?
No — the LS Edge wears a longer slide, and the shell molds around both the slide and the light. Each pairing gets its own dedicated fitment; select your exact gun in the builder.
What warranty comes with it?
