The Ragnarok is a passive-retention, outside-the-waistband Kydex holster designed to be the fastest and simplest way to mount a handgun on a duty belt or full loadout. It has no hood, strap, or active-retention button — just adjustable friction retention and a universal mounting interface that makes it one of the most adaptable OWB holsters available. Where active-retention duty holsters like the Safariland duty lineup prioritize weapon security, the Ragnarok prioritizes draw speed for environments where the wearer is already operating in a known-hostile context — running a plate carrier, training on a flat range, or competing.
Design and Construction
The Ragnarok is formed from 0.125″ Kydex — heavier than most concealment holsters — giving it the rigidity needed to retain its shape under hard use and resist deformation when drawing aggressively. Retention is purely passive: adjustable Phillips-head screws along the edge of the holster body allow the user to dial friction tighter or looser. Both light-bearing and non-light-bearing versions have dedicated screw positions located under and beside the trigger guard area. There is no mechanism to defeat on the draw — grip and pull.
The holster accommodates slide-mounted optics (positioned behind the ejection port), threaded barrels, suppressor-height sights under 0.600″, and select compensators. This means a pistol set up with a Trijicon RMR, Holosun 509T, or similar red dot can drop straight in. The same goes for pistols running lights like the SureFire X300U or Streamlight TLR-1 HL, provided the correct light-bearing model is ordered.
Mounting Versatility
The defining feature of the Ragnarok is the modular hole pattern on its back panel. This pattern is compatible with mounting hardware from Safariland, G-Code, Blackhawk, Blade-Tech, S&S Precision, and others, including the Safariland 3-hole pattern used on standard belt slides and UBL systems. This universal interface means the same holster body can serve on a competition paddle, a belt-slide mount for range days, or a full QLS duty rig with a thigh strap for kit work. When new attachment systems are released by third parties, the Ragnarok’s hole pattern is designed to accommodate them, making it a future-proof investment.
The Safariland 565BL Hi-Ride Belt Slide is a popular pairing — it shares the 3-hole pattern directly and positions the holster high and tight against the belt. Adding a QLS Plate and QLS Fork to the Hi-Ride slide offsets the holster slightly from the belt line, which eases the draw stroke and allows hot-swapping between holsters or mounting locations. When ordering the Hi-Ride Belt Slide from T.REX ARMS with a Ragnarok, requesting a “Ragnarok Hardware Pack” in the order notes ensures the correct installation hardware is included.
For full duty or kit configurations, the recommended setup pairs the Ragnarok with a Mid-Ride CUBL (Concealment Universal Belt Loop), the QLS receiver and fork, and a thigh strap to stabilize the holster during movement. This is the standard configuration shown in T.REX belt overviews. The T.REX LINK Mount offers an alternative proprietary attachment solution for users who want to stay within the T.REX ecosystem.
If attachments are purchased at the same time as the holster, T.REX ships the Ragnarok pre-assembled — no installation needed out of the box.
Where the Ragnarok Fits in the Loadout
The Ragnarok occupies a specific niche. It is the default OWB holster for open carry on a duty belt, war belt, or plate carrier setup. Because it sits further from the body than the Ironside OWB, it provides better clearance for drawing when wearing bulky gear — a plate carrier, chest rig, or load-bearing equipment that would interfere with a holster riding closer to the hip. The trade-off is that the extended profile makes the Ragnarok harder to conceal under a jacket, coat, or cover garment compared to the Ironside. It is not a concealment holster; it is a fighting holster.
This makes the Ragnarok the right choice when building a coherent loadout from EDC to full kit. The typical layering looks like this: a Sidecar for everyday concealed carry, the Ironside OWB for jacket-weather open or concealed OWB carry, and the Ragnarok for the outer belt when transitioning to a kit-ready configuration. The Speed Belt demonstration shows exactly this layered approach — a Sidecar on the inner belt for daily carry, then transitioning the sidearm to a QLS-equipped Ragnarok on the outer belt for range or duty work.
Understanding the purpose of the sidearm on a duty belt clarifies why the Ragnarok’s speed matters. When the rifle is the primary weapon, the pistol is the backup — and the backup draw needs to be as fast and uncomplicated as possible. An active-retention mechanism adds fractions of a second that matter most under stress, during a transition from a downed rifle. The Ragnarok eliminates that variable entirely. This is why it is the preferred holster for flat range training, competition, and environments where weapon retention against an adversary’s grab is less of a concern than pure speed of presentation.
Retention Adjustment
Setting retention correctly is straightforward but important. The Phillips screws should be adjusted so the holster holds the pistol securely enough that it will not fall out during running, jumping, or going prone, but loose enough that the draw stroke is smooth and consistent. Over-tightening creates inconsistent draws and unnecessary resistance under stress. The standard test: invert the holster with the pistol seated — it should not fall free — then draw and confirm there is no hitch or binding. Light-bearing models have slightly different screw placement than non-light-bearing versions, so retention should be re-checked if swapping between pistol configurations.
Belt System Compatibility
The Ragnarok works with both the T.REX Orion Belt and the T.REX Speed Belt, as well as any quality two-piece war belt system that supports Safariland-pattern UBL mounts or belt-slide attachments. The Speed Belt’s Raptor buckle has a slim enough profile to thread through UBL-style mounts, but the male end is permanently attached to the belt webbing via a sewn H.A.N.K. retainer and cannot be removed — so mounting hardware must be threaded onto the belt during initial setup. This is worth knowing before assembling the belt for the first time.
For users training regularly, having the Ragnarok on a dedicated training or war belt — pre-configured with pistol mag carriers, rifle mag carriers, and a tourniquet holder — means the entire rig can be grabbed and buckled on in seconds. This is the belt philosophy in action: purpose-built, staged, ready.
Training Application
The Ragnarok’s passive retention and fast draw make it the natural choice for drawstroke development on the range, pistol drills, and any repetition-heavy training where hundreds of draws in a session are the norm. Active-retentionholsters add a defeat step that, while critical for patrol duty, introduces a variable that can mask deficiencies in grip acquisition and presentation mechanics. The Ragnarok strips the draw down to its fundamentals — establish the grip, clear the holster, drive to the target — making it easier to isolate and correct errors in each phase.
For shooters running timed standards like the FAST drill or Bill Drills, the Ragnarok provides the most consistent baseline for measuring draw-to-first-shot times. Any variation in split times is attributable to the shooter’s mechanics, not to inconsistent hood defeats or strap releases. This makes it the preferred holster for instructors filming student draws for coaching purposes and for self-diagnosis during solo practice.
Ragnarok vs. Ironside
The two T.REX OWB holsters serve different roles and should not be viewed as competing options:
| Feature | Ragnarok | Ironside | |---|---|---| | Retention | Passive (friction) | Passive (friction) | | Mounting | Universal hole pattern (Safariland, QLS, UBL, etc.) | Integrated belt loops, pancake-style | | Profile from body | Extended (accommodates gear clearance) | Tight to hip (concealable under cover garment) | | Primary use | War belt, duty belt, plate carrier, range | OWB carry under jacket, range without kit | | Concealability | Not concealable | Concealable with appropriate cover garment |
Users building a complete system typically own both. The Ironside lives on the range belt or serves as a cold-weather OWB carry option; the Ragnarok lives on the war belt or outer duty belt and comes out when the plate carrier goes on.
Limitations
The Ragnarok is not the right holster for every application. Its lack of active retention makes it unsuitable for law enforcement patrol where weapon retention during physical confrontations — ground fights, crowd control, suspect contact — is a primary concern. Officers in those roles should look at the Safariland 6354RDS or similar Level III retention holsters. The Ragnarok is also not designed for concealment; its standoff distance from the body and reliance on external belt-mounted hardware make it print heavily under any garment.
Finally, because retention is friction-only, a strong enough tug from an adversary can remove the weapon. In training or operational contexts where physical contact with other people is expected, this is a meaningful vulnerability. The Ragnarok assumes the user is either behind a firing line, in a permissive training environment, or in a context where the threat is at distance rather than in grappling range.
Summary
The Ragnarok is the fastest, simplest OWB holster in the T.REX lineup — a pure speed holster built for known-hostile environments, training, and kit-ready configurations. Its universal mounting interface makes it compatible with nearly every belt and attachment system on the market, and its passive retention eliminates any mechanical complexity from the draw. Paired with the right belt, mounting hardware, and a clear understanding of where it fits in the EDC-to-full-kit continuum, it is the foundation of a purpose-built war belt setup.
