Gun Flower Glock 17/19 Level III OWB Holster — Black

OWB (outside the waistband) polymer holster with Level III retention, designed for the Glock 17 and 19 in duty configuration. Aimed at officers, operators and dynamic shooting competitors who require an active retention system with a dual-release sequence — thumb and index finger — before drawing.

The Level III system requires deactivating two retention devices in sequence before the pistol can be drawn. This increases passive security against weapon snatching, at the cost of a fraction of a second compared to a single-retention holster — a trade-off accepted by operators working in public-contact environments or higher-risk situations. Those who prioritise absolute speed in sport shooting should consider lower-retention options.

The belt attachment platform supports belts from 38 to 60 mm wide and allows a choice between Low Ride and High Ride positions, adapting the carry height to the wearer's build and equipment. Compatibility covers Glock 17 Gen3-5, G19 Gen3-6, G19X, G23 Gen3-4, G22 Gen3-4, G31 Gen3-4, G32 Gen3-4, G44 and G45. MOS versions and subcompact models (G26, G43, G48) are not compatible: always verify fit before operational use.

Key points

• Level III dual-release retention (thumb + index finger) reduces the risk of disarmament in close contact compared to passive or single-retention systems.
• The Low Ride / High Ride adjustment lets you adapt the holster position to your kit and body shape without additional tools.
• Compatibility with belts from 38 to 60 mm makes it suitable for most duty belts and modular belt systems on the market.
• Coverage of ten Glock models across the most common generations means the same holster can be retained when switching pistols, provided the new model appears on the compatibility list.
• The polymer body maintains a stable geometry over time with no specific maintenance, unlike leather holsters that require periodic conditioning.
