Custom KYDEX® Holsters for the FN 5.7 MK3
The FN Five-seveN Mk3 is the redesign the platform waited twenty years for — the 2022 rebuild with a factory optics-ready slide, modern trigger, and the ergonomics brought into this decade, while keeping the twenty rounds of 5.7×28 that made the original a category of one. ANR Design builds custom KYDEX® FN 5.7 Mk3 holsters precision-formed in Manchester, NH on a dedicated Mk3 shell — because the Mk3 is dimensionally its own gun, and classic Five-seveN holsters won’t retain it. Optics and suppressor-height sights clear as standard, around twenty weapon-light fitments are available, and Mk3 builds Quick Ship in both hands. IWB, standard OWB, or Nidhogg — configure yours below.

FN 5.7 Mk3 Fitment & Compatibility
Our Five-seveN Mk3 holsters are molded on a dedicated shell formed to the 2022 redesign’s actual geometry — FN changed the gun, so we changed the mold. The Mk3’s factory optics-ready slide and a mounted red dot clear as standard, along with suppressor-height sights, and retention clicks on the trigger guard with full authority. (Running a classic Mk1 or Mk2? That generation has its own dedicated fitment — select it in the builder.)
Carry Options for the FN 5.7 Mk3
Inside the Waistband (IWB): The Mk3 kept the platform’s featherweight full-size formula, and our IWB rig completes it — in-house concealment claw, your choice of injection-molded clips, heat-treated DCC Monoblock steel, or the NeoMag Alias system, with ride height and cant adjustment. Both right- and left-handed builds qualify for our fastest Quick Ship tier.
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. Every shell is molded to the exact gun-and-light combination.
OWB — Standard & Nidhogg: The same dedicated Mk3 fitment and light catalog outside the waistband — belt carry on the Standard OWB, range and working configurations on the Nidhogg.
Spare Magazines: Mk3 magazines run their own pattern, distinct from the classic generations — contact us if you need carriers for them; demand decides what we mold next.
Frequently Asked Questions
Will a classic Five-seveN holster fit my Mk3?
No — the Mk3 is a redesigned gun with its own external dimensions, and Mk1/Mk2-molded shells won’t close or retain correctly on it. Our Mk3 fitment is molded on the actual 2022 pistol.
Will the holster clear a red dot on my Mk3?
Yes — the Mk3’s factory optic cut and a mounted red dot clear as standard on every shell, along with suppressor-height sights, at no extra cost.
Is the FN 5.7 Mk3 holster Quick Ship eligible?
Yes — both right- and left-handed builds qualify for our fastest Quick Ship tier. The builder shows your exact lead time before you order.
Can I get a light-bearing Mk3 holster?
Yes — around twenty molded fitments from the TLR-7 through the Surefire X300 series. Select your exact light in the builder and the shell is formed to that combination.
What warranty comes with an FN 5.7 Mk3 holster?
Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell for the original purchaser — automatic on every order, no registration.
