Custom KYDEX® Holsters for the FN 5.7
The FN Five-seveN is the gun that built its own category — the 5.7×28mm original, twenty rounds of flat-shooting velocity in a pistol that weighs nothing, with a cult following that never needed anyone’s permission. ANR Design builds custom KYDEX® FN 5.7 holsters precision-formed in Manchester, NH — with separate dedicated shells for the classic Mk1/Mk2 and the redesigned Mk3, because FN changed the gun in 2022 and a shell molded for one won’t retain the other. Around twenty weapon-light fitments are available across both generations, in IWB, standard OWB, and Nidhogg configurations — with Mk3 builds Quick Shipping in both hands. Select your generation in the builder below.

FN 5.7 Fitment — Mk1/Mk2 vs Mk3
FN redesigned the Five-seveN in 2022, and the Mk3 is dimensionally its own gun — so we mold it its own shell, separate from the Mk1/Mk2 fitment that covers the classic generations. Select your generation in the builder and retention clicks on your actual pistol, not a close-enough average. Both shells clear suppressor-height sights as standard, with optic accommodation for slide-mounted red dots — including the Mk3’s factory optics-ready slide.
Carry Options for the FN 5.7
Inside the Waistband (IWB): The 5.7’s aluminum-light weight makes it one of the easiest full-size guns to carry all day, 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. Mk3 builds qualify for our fastest Quick Ship tier in both hands; the builder shows the exact lead time for every configuration.
Light-Bearing: Around twenty molded light fitments across both generations, 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 generation-and-light combination.
OWB — Standard & Nidhogg: Both generation fitments and the light catalog outside the waistband — belt carry on the Standard OWB, range and working configurations on the Nidhogg.
Spare Magazines: Classic-generation (Mk1/Mk2) 5.7 magazines have a dedicated fitment in our Pistol Mag builder. Mk3 magazines run their own pattern — contact us if you need carriers for them.
Frequently Asked Questions
Will a Five-seveN Mk2 holster fit the Mk3?
No — the 2022 Mk3 is a redesigned gun with its own external dimensions, which is exactly why we mold it a separate shell. Select your generation in the builder and the fit is correct.
Which generation do I have?
If you bought new from 2022 onward with the flat trigger and factory optics-ready slide, it’s a Mk3. The classic hammerless profile with the ring-style trigger guard is Mk1/Mk2 — both covered on our classic shell.
Can I get a light-bearing FN 5.7 holster?
Yes — both generations support around twenty molded fitments from the TLR-7 through the Surefire X300 series. Select your generation and exact light in the builder.
Is the FN 5.7 holster Quick Ship eligible?
Mk3 builds qualify in both right- and left-handed configurations; classic-generation eligibility varies by platform. The builder shows the exact lead time for your setup before you order.
What warranty comes with an FN 5.7 holster?
Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell for the original purchaser — automatic on every order, no registration.
