Model 6390 Als Mid-ride Level I Retention Duty Holster For Glock 20 Gens 1-4 W/ Light

The Safariland Model 6390 ALS Mid-ride Level I Retention Duty Holster for Glock 20 Gens 1-4 w/ Light is purpose-built for law enforcement and armed professionals who demand reliable, fast-access retention on duty or training operations. Designed to accommodate the full-size Glock 20 with mounted weapon light, this mid-ride holster balances accessibility with security—critical when operating in high-threat environments where reholstering speed and retention integrity determine mission success. The mid-ride cant positions the pistol at an optimal draw angle without excessive offset, enabling consistent presentation across varying body types and duty uniforms.

Level I retention employs Safariland's proprietary friction-based design, locking the firearm into place through molded contact points without external thumb breaks or straps that slow reholstering. The ALS (Automatic Locking System) secures the weapon the instant it enters the holster, providing passive retention that requires only normal trigger-guard contact—no manual engagement needed. Molded specifically for the Glock 20 with light attachment, the holster accommodates aftermarket tactical lights while maintaining the structural integrity and retention geometry that makes Safariland duty gear the standard across federal, state, and local agencies. The mid-ride platform distributes weight evenly along the belt line, reducing fatigue during extended patrol or tactical operations.

This holster serves uniformed officers, plainclothes detectives, and tactical team members who carry the Glock 20—a powerful, magazine-fed platform favored in wilderness law enforcement and specialized units. The compatibility window spans Glock 20 Gens 1 through 4, ensuring backward compatibility with older duty weapons and modern variants. At 0.84 lbs, the holster remains lightweight enough for all-day comfort while providing the structural reinforcement necessary to support the recoil impulse of full-power 10mm ammunition. Installation onto standard duty belts is straightforward; the mid-ride design works seamlessly with traditional leather or modern tactical belt systems.
