Custom KYDEX® Holsters for the Glock 45
The Glock 45 took the 19X’s crossover recipe — full-size grip, compact slide — and dressed it for duty: black, front serrations, no lanyard loop, and it’s been earning police contracts ever since. ANR Design builds custom KYDEX® Glock 45 holsters precision-formed in Manchester, NH — the G45 is explicitly covered on our Glock 19 fitment, because a holster wraps the slide, and the G45 carries the compact one. The full G19 catalog is open to it: IWB, Nidhogg OWB, the Daishō AIWB sidecar, and over twenty molded weapon-light fitments. Left-handed and most light-bearing builds qualify for our fastest Quick Ship tier. Configure yours below.

Glock 45 Fitment — The Crossover Question, Answered
Glock 19 holster or Glock 17 holster? For the G45, it’s the Glock 19 — a holster molds around the slide, and the G45 wears the compact G19 slide on its full-size frame. The G45 is explicitly covered on our G19 precision shell, alongside Gen 3–6, the 19 MOS, 19M, and its crossover twin the Glock 19X, with full audible click retention. The longer grip rides above the shell and doesn’t touch the fitment.
Every Glock 45 holster ships optics-ready for slide-mounted red dots — including MOS models — and clears suppressor-height sights as standard.
Carry Options for the Glock 45
Inside the Waistband (IWB): The G45’s carry challenge isn’t the slide — it’s concealing the full-size grip. Our IWB rig attacks it directly with an in-house concealment claw that rotates the grip into the body, plus your choice of injection-molded clips, heat-treated DCC Monoblock steel, or the NeoMag Alias system, with ride height and cant adjustment. Left-handed and most light-bearing builds qualify for our fastest Quick Ship tier.
Light-Bearing: The full Glock 19 light catalog applies — over twenty molded fitments including the Streamlight TLR-1 / HL / HL-X, TLR-2, TLR-7 / 7A / 7X / HL-X, Surefire X300U-A & B, X400 Ultra, XC1, XC2, XC3, and XVL2, Modlite PL350, Inforce APL, APL 3.0, APLc & WILD 1, Olight PL-Mini, PL-Mini 2, PL-2 & PL-Pro, Sig Foxtrot1X & 2R — and the Glock GTL-10. Every shell is molded to the exact gun-and-light combination — duty light included.
Nidhogg OWB: The same fitment and light catalog outside the waistband — range, working carry, or duty-style configurations for a gun that’s increasingly on duty belts.
Daishō AIWB Sidecar: The Daishō’s Glock 19 shell covers the G45 — holster and magazine carrier bridged by a flexible Tegris wing with adjustable cant, and left-handed builds are Quick Ship eligible. Pair it with a spare-mag carrier from our Pistol Mag builder; the G45’s 17-round magazines are covered on the Glock 9/40 series fitment.
Frequently Asked Questions
Does the Glock 45 take a Glock 19 or Glock 17 holster?
Glock 19 — the holster wraps the slide, and the G45 wears the compact G19 slide. Ours covers the G45 explicitly on the G19 fitment; a G17 holster would leave open space at the muzzle and can compromise retention.
Does the full-size grip affect holster fit?
No — the grip rides entirely above the shell. It affects concealment, not fitment, which is why our IWB rig pairs the G45 with a concealment claw that tucks the grip into the body.
Will this holster fit my Glock 19X too?
Yes — the 19X shares the G45’s crossover layout, and both are covered on the same shell along with the standard G19, Gen 3–6.
Can I get a duty light on a Glock 45 holster?
Yes — the full G19 light catalog applies, from compact TLR-7-class lights through full-size duty lights like the Surefire X300 series and X400 Ultra. Select your exact light in the builder.
What warranty comes with a Glock 45 holster?
Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell for the original purchaser — automatic on every order, no registration.
