Custom KYDEX® Holsters for the FN 510
The FN 510 Tactical brought the 509’s DNA to the big-bore world — 10mm, threaded barrel, optics-ready, and 22-round mags, aimed squarely at the backcountry and hard-use crowd. Its .45 ACP twin, the FN 545 Tactical, shares the platform — and both share one precision fitment here. ANR Design builds custom KYDEX® FN 510 holsters in Manchester, NH on a shell covering the 510 Tactical and 545 Tactical together — threaded barrels cleared through the open muzzle, suppressor-height sights and mounted optics cleared as standard, with around twenty molded weapon-light fitments. Carry it IWB, in our standard OWB — where builds Quick Ship in both hands — or in the Nidhogg. And if you want the platform’s full potential, we build more than the holster: the Sharur, our own compensator designed in-house for the 510 and 545, is right below. Configure yours below.

FN 510 & 545 Tactical Fitment
One ANR Design shell covers the FN 510 Tactical and FN 545 Tactical — the 10mm and .45 twins share the large-frame geometry a holster indexes on, and the Tactical features are handled by design: threaded barrels ride through the open muzzle, suppressor-height sights clear the sight channel, and mounted red dots clear as standard. Retention clicks on the trigger guard with full authority on either caliber.
Carry Options for the FN 510 / 545
OWB — Standard & Nidhogg: The natural home for a big-bore Tactical — belt carry on the Standard OWB, where both right- and left-handed builds qualify for our fastest Quick Ship tier, or working configurations on the Nidhogg with the full light catalog.
Inside the Waistband (IWB): For the committed 10mm carrier — our IWB rig pairs the big frame with an in-house concealment claw and your choice of injection-molded clips, heat-treated DCC Monoblock steel, or the NeoMag Alias system. Made to order, with the exact lead time shown live in the builder.
Light-Bearing: Around twenty molded light fitments, including the Streamlight TLR-1 / HL / HL-X, TLR-2, and TLR-7 series, Surefire X300U-A & B and XC-series, Inforce, Olight, and Sig Foxtrot lights — the classic backcountry pairing of big bore and real lumens, molded as one unit.
Spare Magazines: The FN 510’s magazines have a dedicated fitment in our Pistol Mag builder, built to pair with any holster above.
The Sharur — Our Compensator for the FN 510 & 545
We didn’t stop at the holster. The Sharur is ANR Design’s own compensator, engineered in-house specifically for the FN 510 and 545 Tactical’s threaded barrels — designed, machined, and tested by the same shop that molds your holster. That matters for one reason nobody else can offer: the comp and the holster come from the same drawing board. The holster’s open muzzle clears the Sharur by design, so the full setup — comp, dot, and light — carries as a system, not a collection of parts hoping to cooperate.
Frequently Asked Questions
Does one holster fit both the FN 510 and FN 545?
Yes — the 10mm and .45 Tacticals share the frame and slide geometry a holster molds around, and our shell covers both with full retention. Select either in the builder.
Does the holster clear the threaded barrel?
Yes — the muzzle end is open, so the threaded barrel rides through cleanly with or without a thread protector. The holster is molded for the pistol, not for a mounted suppressor.
Does the holster work with the Sharur compensator mounted?
Yes — the open muzzle clears the Sharur by design; comp, holster, and gun come from the same shop. Find the Sharur in the product grid above.
What is the Sharur?
Our in-house compensator for the FN 510 and 545 Tactical — designed and built by ANR Design for the platform’s threaded barrels. It’s the only comp on the market made by the company that also molds your holster around it.
Will the holster clear a red dot on my 510 or 545?
Yes — mounted optics and suppressor-height sights clear as standard on every shell, at no extra cost.
Is the FN 510 holster Quick Ship eligible?
In our standard OWB builder, yes — both right- and left-handed builds. IWB and Nidhogg configurations are made to order, with the exact lead time shown live before you order.
What warranty comes with an FN 510 holster?
Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell for the original purchaser — automatic on every order, no registration.
