Custom KYDEX® Holsters for the Glock 20
The Glock 20 is the 10mm standard — fifteen rounds of full-power 10mm that’s become the woods gun, hog gun, and backcountry-defense pick of a caliber in full renaissance. ANR Design builds custom KYDEX® Glock 20 holsters precision-formed in Manchester, NH with separate dedicated shells for Gen 2–4 and Gen 5, molded to the generation you actually own. Around twenty weapon-light fitments cover the railed frame, from the TLR-1 through the Surefire X300 series. Carry it IWB or in the Nidhogg OWB for field and trail work. Configure yours below — priced and lead-timed live as you build.

Glock 20 Fitment — Gen 2–4 vs Gen 5
We mold the Glock 20 on two dedicated shells: one for Gen 2–4 (covering the 20, 21, and 21SF of those generations) and a separate one for Gen 5, formed on the fifth generation’s revised geometry. Select your generation in the builder and the click lands on your actual pistol — no “close enough” fitment on a full-power 10mm.
Every Glock 20 holster ships optics-ready for slide-mounted red dots and clears suppressor-height sights as standard.
Carry Options for the Glock 20
Nidhogg OWB: The natural carry for a woods and field 10mm — the dedicated fitment outside the waistband, riding secure through brush and long miles. Pair it with a light and the whole backcountry rig carries as one molded unit.
Inside the Waistband (IWB): Plenty of people carry the G20 daily, and our IWB rig makes the full-size frame civilized — 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.
Light-Bearing: Around twenty molded light fitments, including the Streamlight TLR-1, TLR-2, and TLR-7 series, the Surefire X300U-A & B, XC-series, and XVL2, Modlite PL350, Inforce, Olight, and Sig Foxtrot lights. Every shell is molded to the exact gun-and-light combination.
Spare Magazines: The Glock large-frame 10mm magazines have a dedicated fitment in our Pistol Mag builder.
Frequently Asked Questions
Will a Gen 4 Glock 20 holster fit a Gen 5?
No — the Gen 5 large-frame models changed dimensionally, so we mold separate dedicated shells for Gen 2–4 and Gen 5. Select your generation in the builder for the correct fitment.
Will a Glock 21 holster fit my Glock 20?
Within the same generation range, yes — the 20 and 21 share slide and frame geometry, and our Gen 2–4 shell covers both, along with the 21SF.
Can I get a light-bearing Glock 20 holster for the backcountry?
Yes — around twenty molded fitments from the TLR-1 through the Surefire X300 series, each formed to the exact gun-and-light combination so the field rig carries as one unit.
Can I get a left-handed Glock 20 holster?
Yes — left-hand builds are fully supported and made to order. The builder shows the exact lead time before you order.
What warranty comes with a Glock 20 holster?
Every ANR Design holster includes a free Lifetime Warranty on the KYDEX® shell for the original purchaser — automatic on every order, no registration.
