Custom KYDEX® Holsters for the Glock 17 X400
The Surefire X400 Ultra is the full-size duty light with a laser built in — and its owners know the holster problem by heart: everyone molds for the X300 and hopes the X400’s deeper housing squeezes in. It doesn’t, and we don’t ask it to. ANR Design molds our KYDEX® holsters over the actual Glock 17 + X400 Ultra pairing in Manchester, NH — housing fully enclosed, laser window clear on the draw, retention locked on the gun. The fitment covers the full G17 family — Gen 2–6, 17M, 17 MOS, and the Glock 47 — in IWB and Nidhogg OWB configurations, and this combination qualifies for our fastest Quick Ship tier in both hands.

Glock 17 + X400 Ultra Fitment Details
This holster is molded over the actual pairing — Glock 17 (Gen 2–6, 17M, 17 MOS, or Glock 47) with the Surefire X400 Ultra mounted. The X400’s housing runs deeper than an X300’s to carry its laser module, which is exactly why it needs its own mold: our shell encloses the full unit, keeps the emitter window clear on presentation, and clicks retention on the trigger guard rather than clamping the light. The same fitment covers the Glock 31 running the X400.
Optics-ready and suppressor-height sight clearance come standard — the complete duty stack of red dot, tall sights, and light/laser carries as one molded unit.
Frequently Asked Questions
Will an X300 holster fit my X400 Ultra?
No — the X400’s housing is deeper and shaped differently to carry the laser module, so an X300-molded shell won’t close or retain correctly with it mounted. Ours is a dedicated X400 Ultra fitment, molded to the actual unit.
Does the holster block the X400’s laser?
No — the shell is molded with the emitter window clear on presentation. The laser is usable the moment the gun clears the holster.
Is the Glock 17 X400 holster Quick Ship eligible?
Yes — this combination qualifies for our fastest Quick Ship tier in both right- and left-handed builds, IWB or OWB. The builder shows your exact lead time before you order.
Will this fit my Glock 17 MOS with a red dot and the X400?
Yes — the shell clears slide-mounted optics and suppressor-height sights as standard, so the full MOS + red dot + X400 setup carries without modification.
What warranty comes with it?
Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell for the original purchaser — automatic on every order, no registration.
