The Safariland 537 GLS open top belt slide holster provides a secure and streamlined outside‑the‑waistband carry solution for Glock 19 and Glock 23 pistols. Built from durable leather with a right‑hand orientation, the holster features a belt loop mount that positions the firearm close to the body for stability during movement and comfort during extended wear. The open‑top profile reduces draw resistance, while the molded interior maintains consistent retention and alignment as the firearm is seated.

The integrated Grip Locking System enhances security by automatically engaging when the pistol is holstered, creating a natural retention method that secures the weapon without additional manual steps. The GLS mechanism releases as the firearm is gripped, supporting fast and intuitive access for concealed carry, duty use, or competition settings. Designed specifically around the dimensions of Glock 19 and Glock 23 pistols, the holster balances retention, speed, and comfort in a dependable leather platform suited for both professional and recreational applications.
